Question

4. (a) What is vaccine? (b) How does it work? (c) Why are the children vaccinated?​

Answer 1

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins

Your immune system reacts to the vaccine in a similar way that it would if it were being invaded by the disease — by making antibodies. The antibodies destroy the vaccine germs just as they would the disease germs — like a training exercise. Then they stay in your body, giving you immunity.

For best protection against disease, your child should get vaccinated on time, starting at 2 months of age, and follow the recommended schedule as closely as possible.

Infants and young children are at greater risk from vaccine-preventable diseases because their immune systems are less mature and less able to fight off infection. If an infant or young child were to get a vaccine-preventable disease, it could be very serious and life-threatening.

Vaccinating your child on time gives them the best protection as early as possible

Answer 2

Vaccine is the antidote which is given to fight against the specific disease op virus.
Vaccine contain same disease or virus bacteria which acts against disease bacteria.
Children are vaccinated because they should be free from viruses and diseases
