There are numerous theories about why there has been recent pertussis outbreaks.
One theory on why there are more outbreaks now than in the past is because the acellular component of the vaccine is less effective than whole cell.
Here is an article:
Whole cell pertussis vaccine causes more reactions than acellular.
Here is quote from an op ed after the article:
What are the solutions to this problem? Can we give repeated doses of acellular pertussis vaccine to bolster immunity throughout adolescence and adulthood? How often do the boosters need to be repeated? Or do we need to reconsider going back to the old whole-cell vaccine? For those of us who are old enough to remember the whole-cell pertussis vaccine, we recall that it was associated with a high rate of local and systemic reactions….
I am most interested in hearing from vaxxers, as they are the ones who will be getting the vax.
Until such time as a better vax come along - do you prefer the more effective, but more reactive whole cell? Or do you prefer the less effective, but less reactive DTaP?
