Detailed explanation-1: -Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.

Detailed explanation-3: -For all vaccine-preventable diseases, timely and complete vaccination is the best way to prevent infection.

Detailed explanation-4: -Vaccines contain dead or weakened microbes of a particular disease.
