MONDAY, Sept. 7, 2015 (HealthDay News) -- When babies come down with whooping cough, the odds are good that a sibling is the source, new research reveals.
That's a change from years past, when mothers were most often the source. But the shift is not surprising, said study author Tami Skoff, an investigator with the U.S. Centers for Disease Control and Prevention.
It's been clear for years that cases of whooping cough, or pertussis, are rising in the United States. In 2012, more than 48,000 cases were reported nationwide -- the highest number since 1955, the CDC said.
And older children and teenagers are accounting for a growing proportion of cases.
A major reason for this is that throughout the 1990s, U.S. health officials switched from the traditional whooping cough vaccine to a newer one known as DTaP, out of concerns about rare neurological problems linked to the older vaccine, Skoff said.
The downside is that DTaP's effects don't last as long.
"The vaccine is very effective in the short term," Skoff stressed. But the CDC estimates that whooping cough immunity slowly wanes each year after a child's final dose, which is given around age 5.
If vaccinated children eventually catch the infection, they might not get very sick, Skoff noted.
But they can pass it on to young infants, who are at high risk of becoming severely ill. Of babies younger than 1 year who get whooping cough, half end up in the hospital, according to the CDC.
Newborns' immune systems are too immature to receive the DTaP vaccine right away, 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 18 months, with a final one between the ages of 4 years and 6 years.
Skoff said the best way to protect infants is for mothers to have a whooping cough booster shot -- known as Tdap -- during the third trimester of pregnancy.
That way, she explained, infants are born with some of mom's immune system antibodies against the infection, which offers short-term protection.
