What you need to know about COVID-19 vaccines
Vaccines work by mimicking an infectious agent – viruses, bacteria or other microorganisms that can cause a disease. This ‘teaches’ our immune system to rapidly and effectively respond against it. Traditionally, vaccines have done this by introducing a weakened form of an infectious agent that allows our immune system to build a memory of it. This way, our immune system can quickly recognize and fight it before it makes us ill. That’s how some of the COVID-19 vaccines have been designed. Other COVID-19 vaccines have been developed using new approaches, which are called messenger RNA, or mRNA, vaccines. Instead of introducing antigens (a substance that causes your immune system to produce antibodies), mRNA vaccines give our body the genetic code it needs to allow our immune system to produce the antigen itself. mRNA vaccine technology has been studied for several decades. They contain no live virus and do not interfere with human DNA. For more information on how vaccines work, please visit WHO .
Moving with the times: 1980–1988
UNICEF launches the Child Survival and Development Revolution, a drive to save the lives of millions of children each year. Special emphasis is placed on four low-cost measures: growth monitoring, oral rehydration therapy, promotion of breastfeeding, and immunization (together they are sometimes referred to by the acronym GOBI) A series of posters introduced in the 1980s features the tagline, “What would you like to be when you grow up? Alive!” UNICEF poster UNICEF На серии плакатов, выпущенных в 1980-х годах, размещен слоган “Что бы ты хотел делать, когда вырастешь? Жить!”
Through pandemics and epidemics, hope stays alive
For more than 70 years, we have been working to improve the lives of children and their families. Our mission is made possible by a strong network of talented and dedicated staff that includes physicians, clinicians, logistics experts and communication specialists. As the global COVID-19 pandemic unfolds, we look back at UNICEF's history of responding to health crises the world over, and look ahead to recovering from this one. Филиппины UNICEF/UN03784 Индия, 1961 год. Медицинский работник делает девочке прививку против оспы. UNICEF/UNI41906 Disease prevention Since its beginnings, UNICEF has been at the forefront of disease prevention and revolutionizing children’s health. Working closely with partners like the World Health Organization (WHO), we have seen the eradication of smallpox and the near eradication of polio. Since 1988, the number of children affected by polio has reduced by 99 per cent. Today, some of the same lessons we’ve learned in contact tracing in communities are being applied to reach vulnerable children and their families in some of the remotest parts of the world. Бангладеш, 1989 год. Посол доброй воли ЮНИСЕФ Одри Хепбёрн делает прививку от полиомиелита ребёнку в клинике. In the 1980s UNICEF led the child survival revolution — a shift from treating health issues to preventing them — helping to reduce child deaths by up to nearly 80 per cent in some countries. Our worldwide distribution of oral rehydration solution has helped reduce the number of deaths from diarrhoea — a leading killer of young children — by 60 per cent between 2000 and 2007. Mass immunization campaigns have also played a huge role in protecting children against preventable diseases. For measles alone, about 20 million young people’s lives were saved between 2000 and 2015 thanks to such efforts by UNICEF and partners. HIV and AIDS In 1987, AIDS became the first disease to be debated on the floor of the UN General Assembly. As Member States convened, UNICEF and WHO were already monitoring possible interactions between the disease and immunization and breastfeeding. As infections spread, UNICEF geared its research, policy, planning and fundraising to better understand how to prevent mother-to-child transmission. To equip the public with facts, we supported health education around the world, particularly in sub-Saharan Africa, working tirelessly to inform, educate and protect against stigma and discrimination around HIV and AIDS. Медицинский работник берёт кровь для исследования на ВИЧ Since 2010, 1.4 million HIV infections among children have been averted. The reduction in mother-to-child transmission is viewed as a public health success story. Jointly with partners, UNICEF has set ambitious targets for ending AIDS by 2030. Малыши обнимаются в приюте Swine flu In 2009, the swine flu pandemic swept across the world primarily affecting children and young adults who were otherwise in good health. UNICEF put measures in place to prepare for possible local outbreaks in 90 countries. These measures remained in place after the pandemic with an eye on future outbreaks. Mедицинские работники посещают дома Ebola Within two and a half years of the 2014 outbreak of Ebola in West Africa, more than 28,616 cases and 11,310 deaths had been recorded. During the crisis, UNICEF helped in providing care for ostracized children suspected of being infected, children who lost parents and guardians to Ebola, and the millions who were out of school. Since 2018, with the start of the second-biggest Ebola epidemic ever recorded, we have been working with partners across the region to prevent transmission and protect affected children. Within a year, UNICEF and partners had trained more than 32,400 teachers on how to teach children about Ebola prevention and how to make schools a protective environment. Медицинский работник измеряет температуру Coronavirus (COVID-19) The ongoing COVID-19 pandemic has upended family life around the world. Economic shutdowns, school closures and confinement measures are all having a heavy impact on children now and the longer-term repercussions risk their safety, their well-being and their future. UNICEF is calling for swift global action without which, this health crisis risks becoming a child-rights crisis. ЮНИСЕФ Южный Судан, 2020 год. ЮНИСЕФ располагает сетью, состоящей из 2500 социальных активистов, работающих в течение года для повышения осведомлённости людей о важности соблюдения правил гигиены, иммунизации, питания, защиты детей и образования. UNICEF is on the ground in more than 190 countries, partnering with governments, health workers and other front-line responders to keep children healthy, safe and learning, no matter who they are or where they live. COVID-19 is one of the biggest fights in our history, yet, it is a fight that together we can win. Are you with us?
Strengthening the implementation of health policies
The initiative also promotes and supports multi-disciplinary approaches and teams to address the complex causes of health problems among refugee and migrant children – from trauma, anxiety and over-crowded conditions, to lack of hygiene facilities and immunization. As a result, support from the ‘RM Child-health’ initiative builds trust between refugee and migrant families and health providers. At the Centre for refugees and migrants near Bela Palanka in south-eastern Serbia, for example, the needs of refugee and migrant women have shaped the development of the Community Centre run by ADRA, with its Mother and Baby Corner for women with infants. Here, women can take part in language classes, sports activities and, crucially, in workshops about their own health and rights. “ The most important thing is that all the advice from our doctor is in line with their economic circumstances and current living situation [in Reception centres],” explains social worker Andja Petrovic. “The advice is tailored to their life and I think they particularly like that, because they can see that their situation is acknowledged. Because when they go to a doctor [in other facilities], they get advice that they can’t follow because they don’t have the living conditions for it.” Also in Serbia, funding from the ‘RM Child-health Initiative’ supports work by UNICEF and the Institute of Mental Health that looks beyond the provision of basic health care to assess the scale and nature of substance abuse among refugee and migrant communities. This cutting-edge field research will guide the development of materials and capacity building specifically for health and community workers who are in regular contact with young refugees and migrants, helping these workers to identify and tackle substance abuse by connecting children and youth to support services. As one researcher involved in the research commented: “Most of those children have spent several years without a home or any sense of stability. They can't make a single plan about the future since everything in their life is so uncertain. I can't begin to imagine how frightening that is.” By building greater rapport between frontline workers and children, and by equipping those workers with the support, skills and resources they need, the ‘RM Child-health’ initiative is helping to transform health policies into health practice. This vital work has been particularly crucial in 2020, as frontline workers have had to confront – and adapt to – the greatest public health crisis in living memory: the COVID-19 pandemic.

Five opportunities for children we must seize now
History and science tell us vaccines are the best hope we have of ending this virus and rebuilding our lives and our livelihoods. Yet, as Ridhi reminds us, there is a real risk the What you need to know about a COVID-19 vaccine COVID-19 vaccines will not reach all who need it. Vaccine hesitancy will have a profound effect on our ability to overcome COVID-19. A study of nearly 20,000 adults from 27 countries found that roughly 1 in 4 of them would decline a COVID-19 vaccine. A similar study of Americans showed that unclear and inconsistent messaging from public health officials and politicians could reduce vaccine use. Meanwhile, vaccine misinformation has become a big and growing business. Anti-vaccination entrepreneurs have increased their online following by at least 20 per cent during the pandemic. According to Avaaz, the top 10 websites identified by researchers as spreading health misinformation had almost four times as many views on Facebook as information from established health sites. In short, we are losing serious ground in the fight for trust. And without trust, any COVID-19 vaccine will be useless. But with the global roll-out of COVID-19 vaccines, we now have the opportunity to truly reach every child with life-saving immunizations. The light at the end of the tunnel needs to shine for all.
