Vaccines
Vaccines — including COVID-19 vaccines — work to protect the people who get the vaccine, as well as the people around them.
Vaccines help our bodies fight infections faster and more effectively. A vaccine is a substance that teaches your body to recognize and get rid of viruses or bacteria by triggering a response from your immune system. Vaccines help your body stand ready to protect you from getting sick if you run into the virus or bacteria in the future, even if you’ve already had COVID-19.

Decades of existing research on coronaviruses and vaccines gave scientists a head start on understanding COVID-19 and how to prevent it.

There is no evidence that any vaccines, including COVID-19 vaccines, cause female or male fertility problems.

Current data show that the antibodies you make after a COVID-19 vaccine may recognize and protect against virus variants like Delta and Gamma.
