Q- How long will the COVID-19 vaccine protect me? Will I have to get the COVID-19 shot every year?

A few people who have had COVID-19 have apparently had a second, often milder case of the disease, and researchers are exploring what this means in terms of how long immunity from the coronavirus lasts. Vaccine developers are looking at ways to boost the effectiveness of a vaccine so that it provides longer immune protection than a natural infection with the coronavirus.
