The correct answer is A. Diphtheria.
Triple antigen, also known as DTP or DPT, is a vaccine that protects against three diseases: diphtheria, tetanus, and pertussis (whooping cough). It is given to children as a series of shots, usually at 2 months, 4 months, 6 months, and 15-18 months of age.
Diphtheria is a serious bacterial infection that can cause the throat to become inflamed and blocked. It can also cause the heart, kidneys, and nervous system to become damaged.
Tetanus is a bacterial infection that causes painful muscle contractions. It can be fatal if not treated.
Pertussis is a bacterial infection that causes severe coughing. It can be especially dangerous for infants, who can die from it.
The triple antigen vaccine is very effective at preventing these diseases. It is important to make sure your child gets all of the recommended shots.
