But the CDC estimates that whooping cough immunity slowly wanes every year after a child’s final dose, which is given around age 5. If vaccinated children eventually catch the infection, they could not get very unwell, Skoff noted. But they can move it on to young infants, who are at risky of becoming ill severely. Of babies more youthful than 12 months who get whooping cough, half final end up in the hospital, based on the CDC. Newborns’ immune systems are too immature to get the DTaP vaccine immediately, so babies do not get their first dose until the age of 2 months. That’s followed by doses at 4, 6, and 15 to 1. 5 years, with a final one between the age groups of 4 years and 6 years. Skoff said the best way to protect infants is for mothers to possess a whooping cough booster shot – – known as Tdap – – during the third trimester of pregnancy.
