Vaccines are one of the most effective ways we can stay healthy and prevent ourselves from getting sick.
A vaccine that prevents COVID-19 would teach our immune system to recognize the SARS-CoV-2 virus. Then, whenever we are exposed to the virus, our immune system would be ready to leap into action, fight off the virus, and keep us healthy.
Why do we need COVID-19 vaccines?
Making safe and effective vaccines available and accessible so that people can get vaccinated to protect against COVID-19 has the potential to save millions of lives globally.
