Immunization is a proven and cost-effective public health intervention, saving the lives of millions of children and protecting millions more from illness and disability. Immunization is also a wise financial investment - with every $1 invested in immunization returning an estimated $16 in health-care savings and increased economic productivity. Most countries in Europe and Central Asia have immunization coverage of 95 percent or more for three doses of diphtheria, tetanus and pertussis (DTP), often seen as the measure of national performance on immunization. However, while most national averages for DTP vaccination may be adequate, the regional average is hovering at around 92 percent, a slight decrease from the previous year, which is not high enough to ensure immunity for everyone. Over 70 percent of the region’s unvaccinated infants are from middle income countries, with Ukraine presenting the lowest coverage rate and the greatest challenge. National averages also mask disparities, with Roma children and those from other ethnic and vulnerable groups, including refugee and migrant children, all lagging behind. Measles outbreaks are a growing problem. Last year there were over 10,000 cases of measles in the region. Despite increased coverage of the first dose of the measles vaccine among children (up from 63 percent in 2000 to 93 percent in 2016) more work is urgently needed, as children are not fully protected against measles unless they receive two doses. Currently, second dose coverage is at 88 percent, which does not provide adequate protection. In total, over 500,000 children in the region are still not protected against measles - a life-threatening, but easily preventable disease. There are also concerns about ‘vaccine hesitancy’ – a growing mistrust of immunization among some parents, fuelled by myths and misinformation. Such hesitancy may stem from negative media stories linking a child’s death to immunization without the full facts. It may be influenced by the region’s anti-vaccine movements, which spread anti-immunization messages. Meanwhile, measures to counter vaccine hesitancy and build parental trust in immunization are hampered by a lack of discussion with parents about its importance and the minimal risks. A baby girl receives her vaccination at a clinic in Serbia. A baby girl receives her vaccination at a clinic in Serbia. Donor support for immunization is falling in some countries that still require such support. Elsewhere, the concern is to ensure financial sustainability for immunization programmes once countries ‘graduate’ from the support provided by Gavi (The Vaccine Alliance). Ongoing reforms in some countries are affecting both the structure and financing of immunization programmes. Some countries, challenged by competing priorities at home and inaccessibly priced vaccines on the global market, experienced several vaccine shortages in 2015–2016, sometimes causing critical disruptions of services. These issues are particularly acute in middle-income countries, many of which self-procure vaccines and continue to face significant challenges in achieving financial sustainability of their immunization programmes. Some countries also lack adequate monitoring of vaccine coverage, which is critical to understand and address any gaps. As a result of such challenges, the region faces outbreaks of vaccine-preventable disease, such as a polio outbreak in 2015 and an ongoing measles outbreak in Ukraine – a country where conflict and economic recession have depleted stocks of vaccines and vaccine hesitancy is reducing immunization coverage. There is also an ongoing large measles outbreak in Romania, with over 10,000 cases of the diseases and 38 deaths. During the last five years, measles outbreaks have been registered in Georgia (2013), Kazakhstan (2014), Kyrgyzstan (2015), and Tajikistan (2017). Outbreaks in one country can spread rapidly to others, signalling the interdependence and vulnerability of all countries, whatever their stage of economic development.
In Focus: Immunization
Immunization is one of the world’s most cost-effective public health interventions, saving millions of lives each year, and protecting children from illness and disability. Vaccines have helped to halve the number of child deaths worldwide since 1990 and represent a sound financial investment: every $1 spent on childhood immunizations returns an estimated $44 in economic and social benefits. Despite the achievements of immunization programmes in the Europe and Central Asia Region in recent decades, reported immunization rates are uneven across countries — from as high as 98 percent in Albania to as low as 19 percent in Ukraine. The regional average for Eastern Europe and Central Asia stands at 92 percent, still not high enough to protect all children from preventable diseases. What’s more, there was no improvement in coverage between 2014 and 2016. At national levels, disparities can be shocking, with the most vulnerable children often missing out on immunization. Across the Region, more than half a million children have missed out on their routine measles vaccination, and many countries continue to face outbreaks of vaccine-preventable diseases that threaten the lives and well-being of children. Challenges to immunization include weak political commitment and health systems, ‘vaccine hesitancy,’ and concerns about the financial sustainability of national immunization programmes in middle-income countries. UNICEF knows that the whole Region benefits when ALL countries achieve and maintain high vaccine coverage at both national and sub-national levels. Download file (PDF, 981,23 KB) July 2018
World Immunization Week 2019
Vaccines act as a shield, protecting children and newborn babies from dangerous diseases and saving up to 3 million lives each year. Yet, there are still nearly 20 million unvaccinated and under-vaccinated children in the world today. These children are at risk of serious illness, complications, and even death. Many parents want to vaccinate their children, but can’t because they don’t have access to healthcare. But increasingly, some parents are choosing not to. This reluctance often stems from misconceptions about vaccines, or complacency about the likelihood of getting infected. That’s why staying informed about the benefits of vaccines – and the risks of not getting vaccinated – is more important than ever. This World Immunization Week, UNICEF is launching a global campaign to emphasize the power and safety of vaccines among parents and social media users. From 24-30 April, the Bill & Melinda Gates Foundation will contribute US$1 to UNICEF for every like or share of social media posts using the hashtag #VaccinesWork, up to US$1 million, to ensure all children get the life-saving vaccines they need. Help protect children from deadly diseases by telling parents around the world, #VaccinesWork !
Saving lives one dose at a time - Immunization across Europe and Central Asia
Vaccines protect children against disease and death, saving up to 3 million lives globally every year, and are one of the most cost-effective child survival interventions. In short, #VaccinesWork. The Europe and Central Asia Region continues to enjoy overall high childhood immunization coverage and is polio-free. The benefits of vaccines, however, are spread unevenly. Too many children are still missing the protection they deserve. A mother in Serbia holds her baby during her free vaccination as part of the Serbia's national immunization plan.

Of particular concern is a rebounding of measles in the region, despite a record-low of new cases in 2016, causing over 33,000 cases and 79 deaths. The largest current outbreaks have been in Romania (12,368 cases and 49 deaths including 46 children), Ukraine (16,500 cases, 13 deaths including nine children) and Serbia. Although Serbia has a long and successful tradition in child-health protection, it is currently facing a measles outbreak with nearly 5,000 cases (as of 24 April 2018) which have resulted in 15 fatalities. UNICEF is working with the Ministry of Health to support its response and to improve records of immunization in the future.

Ensuring vaccination levels are high in every country across the region is essential. UNICEF is working to ensure all children are protected against the spread of vaccine-preventable childhood diseases and the best defence is a vaccine-protected population and a strong and responsive health system. The whole region benefits when ALL countries achieve and maintain high vaccine coverage at both national and subnational levels.
What you need to know about COVID-19 vaccines
Vaccines save millions of lives each year and a COVID-19 vaccine could save yours. The COVID-19 vaccines are safe and effective, providing strong protection against serious illness and death. WHO reports that unvaccinated people have at least 10 times higher risk of death from COVID-19 than someone who has been vaccinated. There is also evidence that being vaccinated can help prevent you from spreading the virus, so it protects people around you. It is important to be vaccinated as soon as it’s your turn, even if you already had COVID-19. Vaccines offer more reliable protection than natural immunity. Getting vaccinated is a safer way for you to develop immunity from COVID-19 than getting infected. The COVID-19 vaccines are highly effective, but no vaccine provides 100 per cent protection. Some people will still get ill from COVID-19 after vaccination or pass the virus onto someone else. Therefore, it is important to continue practicing safety precautions to protect yourself and others, including avoiding crowded spaces, physical distancing, hand washing and wearing a mask.
Increasing immunization coverage is priority for Ukrainian Government – Vice Prime Minister of Ukraine
– Ukrainian Vice Prime Minister Pavlo Rozenko, representatives of the Ukrainian Government and the Presidential Administration have expressed their commitment to restore the routine immunization programme in Ukraine. Speaking at a high-level roundtable on immunization, organized by the Ministry of Health of Ukraine and UNICEF on the occasion of World Polio Day, Vice Prime Minister Rozenko said: “Evidence-based medicine confirms the effectiveness of vaccines to prevent diseases such as polio, tetanus or whooping cough. Increasing the rates of immunization coverage is an important task and a priority of the government and a matter of national security.” Ukraine currently has the lowest routine immunization rates in the world. According to the Ministry of Health data, only 30 percent of children in Ukraine were fully immunized against measles, only 10 percent against hepatitis B, and only 3 percent against diphtheria, pertussis and tetanus, as of August 2016. Moreover, only 44 percent of children under 18 months of age were fully immunized against polio. Shortage of vaccine supplies has been one of the main reasons behind the critically low immunization rates in the past years. To address this, at the request of the Ministry of Health of Ukraine, UNICEF has procured a number of high quality certified vaccines to protect children against dangerous vaccine-preventable diseases, namely tuberculosis (BCG), measles, mumps and rubella (MMR), hepatitis B, diphtheria, tetanus and pertussis (DTP), tetanus and diphtheria vaccine for adults (Td), paediatric diphtheria and tetanus (DT), rabies, and bivalent oral polio vaccine (bOPV). The vaccines are now available in health facilities across the country. “This time last year, Ukraine was dealing with a polio outbreak. The comprehensive outbreak response was successfully implemented with the help of international partners, but this success is still fragile”, said Marie-Pierre Poirier, UNICEF Regional Director for Europe and Central Asia. “With such low routine immunization coverage, Ukraine is still at risk of outbreaks of long-forgotten diseases. Today, with millions of doses of vaccines available across the country, there is no reason to delay vaccination. Being vaccinated is fundamental to guarantee child’s right to health and now more than ever, it is important for Ukraine to put in place a strong and effective immunization programme,” she added. Speaking at the event, Professor David Salisbury, Chairman of the European Regional Certification Commission for Poliomyelitis Eradication said: “The polio cases in 2015 in Ukraine happened as a direct consequence of failings in the provision of vaccines for children. Efforts have been made to redress these problems but there is still more that needs to be done to give the children of Ukraine protection from vaccine preventable diseases. I am greatly encouraged by the commitments that have been made today and I look forward to being able to remove Ukraine from our list of polio high-risk countries.” Representatives of the Governments of Canada and the United States of America, who provided funding for the polio outbreak response last year, reaffirmed their support for restoring the routine immunization programme in Ukraine. “Canada worked hard last year with Ukraine’s Health Ministry to get nationwide polio vaccination restarted. We are grateful to the thousands of doctors who helped vaccinate millions of children. This year, we are happy to see that the UN has made more vaccines available. But still, far too many children are not routinely fully vaccinated. I urge Ukrainian parents to take advantage of these free vaccines and protect their children from completely unnecessary illnesses,” said H.E. Roman Waschuk, Ambassador of Canada to Ukraine, speaking at the Roundtable today. "Ukraine must continue to build on the great progress that has been made globally to eradicate polio," explained USAID Ukraine Director Susan Fritz. "These positive developments will only have the necessary impact if there is strong and visible political support from leadership at all levels of the Ukrainian Government." “Myths about vaccination that have been spread in recent years are not rooted in evidence-based medicine. As a result, Ukraine has been dealing with cases of diseases that have been long-forgotten in the rest of the world. It is important that the Vice Prime Minister of Ukraine, the Government and our international partners recognize the problem and are willing to work together with the Ministry of Health of Ukraine to resolve it. Increasing vaccination coverage rates in the country is our priority. This is not only a question of health and life of the citizens of Ukraine. This is a national security issue,” said Dr Ulana Suprun, Acting Minister of Health of Ukraine. “Necessary vaccines are available in all regions of the country. I appeal to all citizens who care about their life and health: get vaccinated and vaccinate your children,” added Dr Suprun.

Immunization services begin slow recovery from COVID-19 disruptions, though millions of children remain at risk from deadly diseases – WHO, UNICEF, Gavi
--- While immunization services have started to recover from disruptions caused by COVID-19, millions of children remain vulnerable to deadly diseases, the World Health Organization (WHO), UNICEF and Gavi, the Vaccine Alliance warned today during World Immunization Week , highlighting the urgent need for a renewed global commitment to improve vaccination access and uptake. “Vaccines will help us end the COVID-19 pandemic but only if we ensure fair access for all countries, and build strong systems to deliver them,” said
Vaccinations with a smile in Uzbekistan
Baby Imona is visiting the clinic, but there is no fear or tension, because Nurse Aziza Abduazimova knows how to put her and her parents at ease. Aziza’s open face and sweet, cheerful manner make all of the children she meets comfortable. “I always meet babies with a smile. Then I answer all of the parents’ questions about vaccinations so that they feel they can trust me with their child’s health. I make the child comfortable, and chat and play with them. I use toys to create a relationship before vaccinating them.” Aziza has been immunising children at Polyclinic #47 in Tashkent, Uzbekistan for six years now. She says that she loves her job. “I’m a mother myself. I have three sons aged 15, 12 and 10 years old who are all vaccinated and growing up healthy. I didn’t have a moment’s hesitation in getting my children vaccinated, and I am happy to help other mothers raise strong and healthy kids.” Aziza believes that it’s much better to vaccinate a child and prevent a disease than treat the sometimes-serious consequences of an illness. “Polio can cause permanent paralysis. Mumps, a common childhood disease, can make boys infertile, and measles can be fatal. It’s not just the consequences for the individual, either. A child who hasn’t been vaccinated is putting everyone else at risk, including babies and unvaccinated adults.” Nurse Aziza Abduazimova administers the polio vaccine to baby Imona. Nurse Aziza Abduazimova administers the polio vaccine to baby Imona. However, despite all the evidence about the safety of vaccines to prevent serious disease, some parents are still hesitant. “It’s a natural urge for a mother to protect her baby, and some mothers are scared to cause their baby the pain of an injection,” Aziza says. “Believe me, when I first started this job, I used to cry along with the babies, but then I realised that by causing this brief moment of pain, I’m preventing a lot of future suffering.” Some parents read things on the internet that scare them. Aziza says, “I follow a lot of discussions on the web and I often post evidence to prove that they needn’t worry. All the vaccines used in Uzbekistan meet international standards.” Aziza recalls a young mother who didn’t vaccinate her first son. “He got every childhood disease, one after the other, including Hepatitis A. With my encouragement she decided to vaccinate her younger son. He has grown up very healthy. Now when people see them together, they assume the younger one is older because he wasn’t sick as often, he’s so much taller and stronger than his brother. His mother tells everyone her story. She says, ‘If I’d had my older son vaccinated, I wouldn’t have gone through all these troubles.’” Aziza helps parents who have concerns about vaccinations to meet mothers and fathers with children who have been fully immunised. “Peer to peer conversations are really helpful because parents trust fellow parents and they can see the results.” She believes being a good vaccinator isn’t just about following procedures but having the right attitude: “There was one lady who came from outside our clinic’s catchment area. She was surprised to find me so cheerful and friendly. In her previous experiences staff had been professional, but she told me my friendliness has made such a difference to her children; now they feel at ease during and after vaccinations. It makes such a difference how you treat people." "Children pick up a lot from how you deal with them—they connect with a smile.” - adds Aziza. Nurse Aziza puts baby Imona at ease with a toy after administering a vaccine. With toys and smiles, baby Imona is at ease after receiving a vaccine. “My main message to parents would be to follow the vaccination calendar. Don’t wait or delay; it has been developed to protect against the most common diseases in this country and vaccinating on time gives your child the best protection.” Aziza gives baby Imona a last cuddle. She smiles, “Parents share the hope that their child will grow up healthy. In my work as a vaccinator, I can help make that happen.” UNICEF in Uzbekistan trains health professionals across the country to vaccinate children and works closely with the Government to ensure the vaccine system is safe and can reach all children with life-saving immunizations.
UNICEF reaches almost half of the world’s children with life-saving vaccines
– UNICEF procured 2.5 billion doses of vaccines to children in nearly 100 countries in 2016, reaching almost half of the world’s children under the age of five. The figures, released during World Immunization Week, make UNICEF the largest buyer of vaccines for children in the world. Nigeria, Pakistan and Afghanistan, the three remaining polio-endemic countries, each received more doses of vaccines than any other country, with almost 450 million doses of vaccines procured to children in Nigeria, 395 million in Pakistan and over 150 million in Afghanistan. UNICEF is the lead procurement agency for the Global Polio Eradication Initiative. Access to immunization has led to a dramatic decrease in deaths of children under five from vaccine-preventable diseases, and has brought the world closer to eradicating polio. Between 2000 and 2015, under five deaths due to measles declined by 85 per cent and those due to neonatal tetanus by 83 per cent. A proportion of the 47 per cent reduction in pneumonia deaths and 57 per cent reduction in diarrhea deaths in this time is also attributed to vaccines. Yet an estimated 19.4 million children around the world still miss out on full vaccinations every year. Around two thirds of all unvaccinated children live in conflict-affected countries. Weak health systems, poverty and social inequities also mean that 1 in 5 children under five is still not reached with life-saving vaccines. “All children, no matter where they live or what their circumstances are, have the right to survive and thrive, safe from deadly diseases,” said Dr. Robin Nandy, Chief of Immunization at UNICEF. “Since 1990, immunization has been a major reason for the substantial drop in child mortality, but despite this progress, 1.5 million children still die from vaccine preventable diseases every year.” Inequalities persist between rich and poor children. In countries where 80 per cent of the world’s under-five child deaths occur, over half of the poorest children are not fully vaccinated. Globally, the poorest children are nearly twice as likely to die before the age of five as the richest. “In addition to children living in rural communities where access to services is limited, more and more children living in overcrowded cities and slum dwellings are also missing out on vital vaccinations,” said Nandy. “Overcrowding, poverty, poor hygiene and sanitation as well as inadequate nutrition and health care increase the risk of diseases such as pneumonia, diarrhea and measles in these communities; diseases that are easily preventable with vaccines.” By 2030, an estimated 1 in 4 people will live in urban poor communities, mainly in Africa and Asia, meaning the focus and investment of immunization services must be tailored to the specific needs of these communities and children, UNICEF said.
Governments must invest in immunizing the most vulnerable children and addressing vaccine hesitancy
- “UNICEF is urging governments in Europe and Central Asia to invest in health systems that prioritize reaching the most vulnerable children with life-saving immunizations alongside national campaigns to address the concerning trend of growing vaccine hesitancy.” “Immunization is one of the most significant and cost-effective public health achievements in modern times. Vaccines save children’s lives and stop the spread of diseases. “Sustainable immunization coverage is only possible through well-functioning health systems that reach all children, including children from minority communities, those living in poverty or children uprooted from their homes. Coverage must be monitored so breakdowns in availability and services are rapidly identified and addressed. “Demand from caregivers and communities equipped with the knowledge to overcome misconceptions and protect their children is equally critical. Misinformation on vaccines has grave implications. Governments must closely monitor public perceptions, counteract misinformation and promote the benefits of immunization. “Measles outbreaks and pockets of unacceptably low vaccination rates are stark reminders that achieving universal routine immunization coverage must be a priority for governments, communities and caregivers.
What are vaccines? Vaccines are products that are usually given in childhood to protect against serious, often deadly diseases. By stimulating your body’s natural defenses, they prepare your body to fight the disease faster and more effectively. How do vaccines work? Vaccines help your immune system fight infections more efficiently by sparking your immune response to specific diseases. Then, if the virus or bacteria ever invades your body in the future, your immune system will already know how to fight it. Are vaccines safe? Vaccines are very safe. Your child is far more likely to be hurt by a vaccine-preventable disease than by a vaccine. All vaccines go through rigorous safety testing, including clinical trials, before they are approved for the public. Countries will only register and distribute vaccines that meet rigorous quality and safety standards. Why should I vaccinate my child? Vaccines save lives. Measles vaccines alone are estimated to have prevented over 21 million deaths between 2000 and 2017. Vaccines will help protect your child against diseases that can cause serious harm or death, especially in people with developing immune systems like infants. It’s important to vaccinate your child. If not, highly contagious diseases such as measles, diphtheria and polio, which were once wiped out in many countries, will come back. Can my baby handle all of these vaccines? Yes. Many parents worry that multiple vaccines will overload their child’s immune system. But children are exposed to hundreds of germs every day. In fact, a common cold or sore throat will put a greater burden on your child’s immune system than vaccines. But these diseases are not present in my community. Do I still need to vaccinate my child? Yes. Although the diseases may be eliminated in your country or region, our increasingly interconnected world means that these diseases could spread from areas where they are still present. What is herd immunity? If enough people in your community are immunized against a certain disease, you can reach something called herd immunity. When this happens, diseases can’t spread easily from person to person because most people are immune. This provides a layer of protection against the disease even for those who cannot be vaccinated, such as infants. Herd immunity also prevents outbreaks by making it difficult for the disease to spread. The disease will become more and more rare, sometimes even disappearing entirely from the community. Can a vaccine cause my baby to get sick? Vaccines are extremely safe and serious side effects are rare. Almost all sickness or discomfort after vaccination is minor and temporary, such as a soreness at the injection site or mild fever. These can often be controlled by taking over-the-counter pain medication as advised by a doctor, or applying a cold cloth to the injection site. If parents are concerned, they should contact their doctor or health care provider. Extensive studies and research show that there is no evidence of a link between vaccines and autism. What diseases do vaccines prevent? Vaccines protect your child against serious illnesses like polio, which can cause paralysis; measles, which can cause brain swelling and blindness; and tetanus, which can cause painful muscle contractions and difficulty eating and breathing, especially in newborns. For a list of the most common vaccines and the diseases they prevent, see this list of the most common vaccines and the diseases they prevent . Can I delay the vaccine schedule? One of the best ways you can protect your child is to follow the recommended vaccine schedule in your country. Any time you delay a vaccine, you’re increasing your child’s vulnerability to disease. Can I let my child get the chickenpox instead of getting the vaccine? Although chickenpox is a mild disease that many parents will remember from childhood (the vaccine was introduced in 1995), some children will develop serious cases with complications that can be fatal or cause permanent disabilities. The vaccine eliminates the risk of complications from the disease, and prevents children from infecting their siblings, friends and classmates. What is the recommended vaccine schedule? Immunization schedules vary by country depending on which diseases are most prevalent. You can find an overview of the recommended vaccines and approximate dates from your local health centre, doctor or your government’s Ministry of Health. >> Learn more about immunization >> World Immunization Week
Over 20 million children worldwide missed out on measles vaccine annually in past 8 years, creating a pathway to current global outbreaks - UNICEF
– An estimated 169 million children missed out on the first dose of the measles vaccine between 2010 and 2017, or 21.1 million children a year on average, UNICEF said today. Widening pockets of unvaccinated children have created a pathway to the measles outbreaks hitting several countries around the world today. “The ground for the global measles outbreaks we are witnessing today was laid years ago,” said Henrietta Fore, UNICEF Executive Director. “The measles virus will always find unvaccinated children. If we are serious about averting the spread of this dangerous but preventable disease, we need to vaccinate every child, in rich and poor countries alike.” In the first three months of 2019, more than 110,000 measles cases were reported worldwide – up nearly 300 per cent from the same period last year. An estimated 110,000 people, most of them children, died from measles in 2017, a 22 per cent increase from the year before. Two doses of the measles vaccine are essential to protect children from the disease. However, due to lack of access, poor health systems, complacency, and in some cases fear or skepticism about vaccines, the global coverage of the first dose of the measles vaccine was reported at 85 per cent in 2017, a figure that has remained relatively constant over the last decade despite population growth. Global coverage for the second dose is much lower, at 67 per cent. The World Health Organization recommends a threshold of 95 per cent immunization coverage to achieve so-called ‘herd immunity’.
