The world is in the midst of a COVID-19 pandemic. As WHO and partners work together on the response -- tracking the pandemic, advising on critical interventions, distributing vital medical supplies to those in need--- they are racing to develop and deploy safe and effective vaccines.
Vaccines save millions of lives each year. Vaccines work by training and preparing the body’s natural defenses – the immune system – to recognize and fight off the viruses and bacteria they target. After vaccination, if the body is later exposed to those disease-causing germs, the body is immediately ready to destroy them, preventing illness.
As of 12 January 2022, WHO has evaluated that the following vaccines against COVID-19 have met the necessary criteria for safety and efficacy.
