Will the vaccine make me sick with Covid-19?

No, the Covid-19 vaccines will not make you sick with the virus. None of the Covid-19 vaccines authorized by the Food and Drug Administration (FDA) or currently under consideration for approval contain the live virus. Instead, these vaccines teach our immune systems how to identify and fight off the virus.

Vaccine Side Effects

Some people report sore arms, slight fevers, headaches, and other minor symptoms after being vaccinated. But that's normal -- so there's no need to worry. In fact, these symptoms are a sign that the vaccine is working and triggering an immune response that protects you from the virus. Any routine symptoms should go away in one or two days.

It Takes Time

It can take a few weeks for the vaccine to do its job and build up protection. During that time, it is still possible to contract and test positive for Covid-19, even though the vaccine itself will not give you the virus.
