Explanation
•Infants that are not immune to pertussis (Whooping Cough) have a high risk of mortality if they are exposed. Healthy adults and older children are more likely to have a full recovery without complications.
•DTaP is normally given over five doses starting at the age of 2 months.
Incorrect options:
•The thymus begins to atrophy by the early teens, but this is not the reason for administering the DTaP vaccine during infancy.
•The ability to crawl is not a factor in the scheduling of immunizations.
•Allergic reactions are not less common in infants. Allergic reactions, although rare, can happen at any age of administration.
