Key Things to Know About COVID-19 Vaccines

What we are still learning

Scientists are still learning how well vaccines prevent you from spreading the virus. We’re also still learning how long COVID-19 vaccines protect people.

Although COVID-19 vaccines are effective at keeping you from getting sick, scientists are still learning how well vaccines prevent you from spreading the virus that causes COVID-19 to others, even if you do not have symptoms. Early data show that vaccines help keep people with no symptoms from spreading COVID-19, but we are learning more as more people get vaccinated.

We’re also still learning how long COVID-19 vaccines protect people.

For these reasons, people who have been fully vaccinated against COVID-19 should keep taking precautions until we know more, like wearing a mask in indoor public places, avoiding large indoor gatherings, and washing your hands often. Vaccinated people do not need to wear masks outside except in crowds.
