The acellular pertussis vaccine does not prevent colonization of the bacteria. A peer-reviewed consensus paper, signed by 16 of the world's leading pertussis experts, confirmed it. The vaccine does not reduce the circulation of B. pertussis and provides no herd immunity.

What it does do is suppress symptoms. A vaccinated person can carry and transmit the bacteria without knowing they are sick, which turns them into an asymptomatic spreader. The unvaccinated person who gets sick feels sick, stays home, and is known to be contagious.

The vaccinated person feels fine, goes to work, goes to school, and spreads it everywhere.

The entire justification for mandating this vaccine rests on a transmission benefit the science says does not exist.
