One big reason is that even though they receive the diphtheria, tetanus, and acellular pertussis vaccine (DTaP), it isn't until they get the 3rd dose when they are six months old that they are
protected against whooping cough as infants.
Childhood Vaccines • In San Francisco's Bay Area schools at least 40 % of kids are not vaccinated, leaving them
unprotected against whooping cough, measles and other preventable disease — part of a nationwide trend toward parents withholding vaccinations.
A new study from Kaiser Permanente's Vaccine Study Center found that the Tdap booster vaccine provides moderate protection
against whooping cough during the first year after vaccination, but its effectiveness wanes to less than 9 percent after four years among teenagers who have received only a newer form of the whooping cough vaccine (acellular pertussis vaccine) as infants and children.
Certain vaccines are actually recommended during pregnancy: the Tdap vaccine (tetanus, diphtheria, and pertussis), which helps
protect against whooping cough, as well as the flu shot.
Because babies can not be
vaccinated against whooping cough (also called pertussis) until they are two months old, it's important that you pass the antibodies to your baby before birth by getting the Tdap yourself.
ORLANDO, FLORIDA — A vaccine
against whooping cough has lost its edge because new, slightly different strains of the bacterium have emerged, researchers say.
Vaccination is still the only way to protect
against whooping cough, especially for the youngest babies who are most at risk of severe illness,» stressed Associate Professor Lan.
'' [Pertusis toxin] is really quite an amazing molecule, and it's been highly essential in the vaccine
against whooping cough,» said Dene Littler, the research fellow who led the work.
