When a disease-carrying microbe enters our body, the body produces antibodies to fight the invader. The antibodies remain in the body and we are protected from the disease-causing microbes. This is how a vaccine works.
Vaccines can sometimes cause a mild reaction, such as soreness at the injection site or a slight fever. However, there are usually no serious adverse events associated with immunisation. Severe allergic reactions or serious side effects very rarely occur. But people with weakened immune systems and pregnant women are vulnerable to the disease and should consult their doctor before being vaccinated.
