disease, by inducing or increasing the natural immunity
mechanisms. Prior to 1995, such preparations usually
contained killed organisms of the type for which immunity

  • Vaccines and immunization: What is vaccination?
    Vaccine ingredients can look unfamiliar when they are listed on a label However, many of the components used in vaccines occur naturally in the body, in the environment, and in the foods we eat All of the ingredients in vaccines – as well as the vaccines themselves - are thoroughly tested and monitored to ensure they are safe
  • COVID-19 vaccines - World Health Organization (WHO)
    WHO’s COVID-19 dashboard also features the number of vaccine doses administered globally, with more detail provided on the dedicated COVID-19 vaccination dashboard At a regional level, there is an AFRO COVID-19 vaccines dashboard and a PAHO COVID-19 vaccines deliveries dashboard
  • Vaccines and immunization - World Health Organization (WHO)
    When you get a vaccine, your immune system responds We now have vaccines to prevent more than 20 life-threatening diseases, helping people of all ages live longer, healthier lives Immunization currently prevents 3 5 million to 5 million deaths every year from diseases like diphtheria, tetanus, pertussis, influenza and measles
  • How do vaccines work? - World Health Organization (WHO)
    Before the measles vaccine was introduced in 1963, major epidemics occurred every few years, causing an estimated 2 6 million deaths annually, mostly among young children Between 2000 and 2023, measles vaccination prevented an estimated 60 million deaths
  • COVID-19 Vaccines Advice - World Health Organization (WHO)
    Unprecedented scientific collaborations, extensive prior research and substantial public funding enabled swift COVID-19 vaccine development to be completed in record time – while maintaining high safety standards New versions of the vaccine are being developed as the COVID-19 virus continues to circulate and change
  • A Brief History of Vaccination - World Health Organization (WHO)
    A plasma-derived inactivated vaccine is approved for commercial use from 1981 to 1990, and a genetically engineered (or DNA recombinant) vaccine, developed in 1986, is still in use today The measles vaccine (1963) is combined with the recently developed vaccines against mumps (1967) and rubella (1969) into a single vaccination (MMR)
  • Vaccine efficacy, effectiveness and protection
    Vaccine efficacy tells us how much the vaccine lowers the risk of the outcome (e g , getting sick) in a trial setting For example, if a vaccine has an efficacy rate of 80%, it means that the vaccinated group had an 80% lower risk of developing disease than the unvaccinated group (those who received the placebo)
  • Know the facts - World Health Organization (WHO)
    When you get a vaccine, your immune system responds We now have vaccines to prevent more than 30 life-threatening diseases and infections, helping people of all ages live longer, healthier lives Immunization currently prevents 3 5 million to 5 million deaths every year from diseases like diphtheria, tetanus, pertussis (whooping cough

  • Vaccines and immunization: Dengue - World Health Organization (WHO)
    TAK-003 is a live-attenuated vaccine containing weakened versions of dengue virus serotypes 1, 2, 3 and 4 developed by Takeda TAK-003 uses the DENV2 strain as the genomic backbone The vaccine schedule is a 2-dose series three months apart, given to specific age groups and in specific circumstances according to WHO recommendations
