What Would a COVID-19 Vaccine Do?
When you come into contact with viruses or bacteria, your body’s immune system makes antibodies to fight them off.
A vaccine forces your immune system to make antibodies against a specific disease, usually with a dead or weakened form of the germs.
Then, if you come into contact with them again, your immune system knows what to do. The vaccine gives you immunity, so you don’t get sick or so your illness is much milder than it otherwise would have been.
A vaccine against COVID-19 would slow its spread around the world. Fewer people would get sick, and more lives could be saved.
