That’s easy! 🙂
Any vaccine who’s efficacy is less than 100%
Really? One example, I've never heard anyone tell someone to get a tetanus/pertussis shot to protect others who've received the same vaccine, have you?
This is too easy...I bet you think Biden is doing a good job too. Keep drinking that corn pop, chump.
https://www.cdc.gov/pertussis/about/faqs.html#preventedIn general, DTaP vaccines are 80% to 90% effective. Among kids who get all 5 doses of DTaP on schedule, effectiveness is very high within the year following the 5th dose – at least 9 out of 10 kids are fully protected. There is a modest decrease in effectiveness in each following year. About 7 out of 10 kids are fully protected 5 years after getting their last dose of DTaP and the other 3 out of 10 kids are partially protected – protecting against serious disease
Q: I’ve heard about parents refusing to get their children vaccinated and travelers to the United States spreading disease; are they to blame for pertussis outbreaks?
A: Even though children who haven’t received DTaP vaccines are at least 8 times more likely to get pertussis than children who received all 5 recommended doses of DTaP, they are not the driving force behind the large-scale outbreaks or epidemics. However, their parents are putting them at greater risk of getting a serious pertussis infection and then possibly spreading it to other family or community members.
We often see people blaming pertussis outbreaks on people coming to the United States from other countries. This is not the case. The United States never eliminated pertussis like polio, so there’s always the chance for it to get into a community. Plus, every country vaccinates against pertussis.
