Cách sử dụng
A vaccine is a medicine that helps to protect you from getting sick. It works by tricking your body into thinking that it has already fought off a disease, so that it is better prepared to fight it off for real if you are exposed to it in the future. Vaccines are usually given as injections or as drops or sprays that you put in your mouth, and they are most often used to prevent diseases like measles, chickenpox, or the flu. It's important to get vaccinated to stay healthy and avoid getting sick.
