IMMUNOLOGY

Detailed explanation-1: -Vaccination is the safest and most common way to gain immunity against a bacteria or virus that your body has yet to encounter. Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against.

Detailed explanation-2: -The vaccine triggers the body’s immune system to produce antibodies against the killed or weakened pathogens introduced inside the body. This way, a memory immune response is created, just like a training exercise.

Detailed explanation-3: -Vaccinations prevent diseases that can be dangerous or even deadly. They reduce the risk of infection by working with the body’s natural defenses to develop immunity safely. Vaccinations can benefit both the people who get them and vulnerable, unvaccinated people around them.
