The nurse is preparing to administer a diphtheria, tetanus, and pertussis immunization to a 3-month-old boy. The infant's mother asks why he needs the DTaP immunization at this age. Which of the following information should be given to her?

Infants that contract pertussis have a high mortality rate


•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.
