Information on vaccines
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.
There are several safe and effective vaccines that prevent people from getting seriously ill or dying from COVID-19.
