Hi Lauren,
Thank you for sharing your question with the EmpowHER community.
Vaccines protect you by preparing your immune system to recognize and fight serious, and sometimes deadly, diseases. A vaccine contains a specific part of a germ (bacteria or virus), called an antigen. The antigen is killed or disabled before it's used to make the vaccine, so it can't make you sick.

I hope this helps.
Be well,
