CONCLUSIONS of these world experts:
- The vaccines in use “cannot avoid infection and transmission.”
- Pertussis vaccines “do not prevent colonization. Consequently, they do not reduce the circulation of B Pertussis and do not exert any herd immunity effect.”
NOTE: The vaccine may provide some personal protection against symptoms, but it makes you an asymptomatic spreader.
NOTE: How much personal protection do you get? According to two studies reported on the CDC website, the vaccine was 73% and 68.8% effective at reducing symptoms within one year of vaccination, but after 2 to 4 years, the post-vaccination effectiveness decreased to 34% and then after 4 years, it decreased to 8.9%.

NOTE: Today Pertussis can be treated with the antibiotic Azithromycin (the z-pak)
