How do vaccinations protect you from future infections?
A
injecting you with antibodies to cause a small immune response
B
injecting you with dead or inactive pathogens to cause a small immune response
C
injecting you with white blood cells to cause a small immune response
D
preventing bacteria from replicating
Explanation: 

Detailed explanation-1: -When you get a vaccine, it sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again. And since vaccines are made of very small amounts of weak or dead germs, they won’t make you sick.

Detailed explanation-2: -Vaccines work by stimulating a response from the immune system to a virus or bacterium. This creates a ‘memory’ in the immune system. This immune memory allows the body to ‘remember’ a specific virus or bacterium, so that it can protect itself against this virus or bacterium and prevent disease that it causes.

Detailed explanation-3: -Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

Detailed explanation-4: -Inactivated vaccines use the killed version of the germ that causes a disease. Inactivated vaccines usually don’t provide immunity (protection) that’s as strong as live vaccines. So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.
