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 .
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.

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?
Safeguarding the health of refugee and migrant children during COVID-19
, the initiative has supported UNICEF’s efforts to improve the immunization process for refugee children and migrants by strengthening the assessment and monitoring process. As a result of such efforts, refugees and migrants have been included in the national COVID-19 Immunization Plan.
