pertussis

Run a test for pertussis even though your child didn't have the symptoms for the disease?

Found the a cellular pertussis VAX to be 53-64% effective.

The same thing you tell a parent of a child that dies of pertussis caught from an unvaccinated schoolmate.

My understanding is that the pertussis vaccine, by its nature, does not prevent infection at all.

It inures you to the pertussis toxin, causing you to experience milder or no symptoms when you do get infected.

People had really really bad reactions to the regular pertussis to the point that people routinely advised new parents not to get it for their children.

For pertussis the threshold is over 90% for prevention assuming that 100% of the population is immunized.

It is clear that the current acellular vaccines were adopted because of safety concerns about former cellular pertussis vaccines.

> Similar irrational fears prompted the development of the "acellular" version of the pertussisThose fears were not in the slightest irrational.

"Estimates of true allergic, or immediate hypersensitivity, reactions to routine vaccines range from 1 per 50000 doses for diphtheria-tetanus-pertussis to approximately 1 per 500000 to 1000000 doses for most other vaccines.

Pertussis is a serious illness, and now that many people refuse to use the vaccine, and even the people who use it can only get a type of vaccine that is less effective than the first vaccine,[1] the whole population is needlessly at risk for pertussis outbreaks.
