Once you've gotten vaccinated it takes several weeks for the body to develop immunity, so you'll need to continue taking precautions like social distancing and wearing masks to reduce your risk of infection during that time.

Over time, as more people get vaccinated and infection rates decline, it may become safe to ease up.
