The difference is in the dosage, with the upper case letters meaning higher quantity. The acellular vaccine uses selected antigens of the pertussis pathogen to induce immunity. Because it uses fewer antigens than the whole cell vaccines, it is considered safer, but it is also more expensive. Recent research suggests that the DTP vaccine is more effective than DTaP in conferring immunity; this is because DTaP's narrower antigen base is less effective against current pathogen strains. Two Tdap vaccines are available in the U. Adacel, manufactured by Sanofi Pasteur , is licensed for use in adults ages 11 to

One of the booster doses should contain the pertussis antigen Tdap. A single dose of Tdap is recommended to be given in pregnancy, ideally in the third trimester, between pregnancy weeks 28 and Before the vaccination was available, diphtheria was a major cause of death in children.
