How do COVID-19 vaccines work?

Pfizer/BioNTech, Moderna, AstraZeneca, Johnson & Johnson, Sinovac and Sputnik V are just a few of the COVID-19 vaccines already developed and approved for use. This is why the InterAcademy Partnership (IAP) decided to celebrate World Immunization Week 2021 by releasing a new infographic and shed some light on the different types of COVID-19 vaccines, how they are developed, and how they work.

Vaccines will play a major role in ending the COVID-19 pandemic. COVID-19 vaccines have already been proven highly effective at preventing severe illness, hospitalisation and death.
