Thanks for the link backing up your bullshit, pussyfart. 
81 Percent of Whooping Cough Cases Occurred in People Who Were Fully Vaccinated CDC data shows 84 percent of children under the age of 3 have received at least FOUR DTaP shots—which is the acellular pertussis vaccine that was approved in the United States in 1996—yet, despite this high vaccination rate, whooping cough still keeps circulating among both the vaccinated and unvaccinated.
More likely than not, the vaccine provides very little if any protection, and this was evidenced very clearly in a study published in Clinical Infectious Diseases.i
Researchers reviewed data on every patient who tested positive for pertussis between March and October 2010 at the Kaiser Permanente Medical Center in San Rafael, California.
Out of these 132 patients:
81 percent were fully up to date on the whooping cough vaccine
8 percent had never been vaccinated
11 percent had received at least one shot, but not the entire recommended series
