Detailed explanation-1: -For some diseases, you need more than one shot to build strong immunity. For others, your protection wears off over time. And some viruses change, or mutate, over time, making your vaccine less effective. For most vaccinations, you need one more jab after the initial series to get more protection.

Detailed explanation-2: -New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months1.

Detailed explanation-3: -Use an ice pack or cool, damp cloth to help reduce redness, soreness and/or swelling at the place where the shot was given. A cool bath can also be soothing. Drink liquids often for 1-2 days after getting the vaccine. Take an over the counter pain reliever unless you have any specific contraindication.

Detailed explanation-4: -Vaccines contain dead or weakened microbes of a particular disease. When a vaccine is introduced into a healthy body, the body fights and kills them by producing suitable antibodies. These antibodies remain in the body and protects it from the microbe when it invades the body again.
