I know only one vaccine that might have 100% efficacy after 4 shots. It is polio vaccine.
COVID-19 has been so far a scourge - when we get enough people vaccinated in developed countries, another variant appears from developing countries. The vaccine deployments has been just too slow around the world.
My hope is that the developing world has seen now enough of the virus and is mainly immune or will be after Omicron has swept over (being hopefully milder than previous variants).
- logic_beats_pro 5y agoHighly unlikely that your 100% statistic is true. Polio rages on today in Africa because of one reason: the oral polio vaccine. Wild type polio has actually been eliminated but sixteen African nations are battling outbreaks of what's called "vaccine-derived polio." https://www.npr.org/sections/goatsandsoda/2020/08/25/905884740/africa-declares-wild-polio-is-wiped-out-yet-it-persists-in-vaccine-derived-cases https://www.npr.org/sections/goatsandsoda/2020/08/25/9058847...
- nojokes 5y agoWell, this is what CDC claims https://www.cdc.gov/vaccines/vpd/polio/hcp/effectiveness-duration-protection.html https://www.cdc.gov/vaccines/vpd/polio/hcp/effectiveness-dur... Yes, I know about this mutated live vaccine. It for sure looked like a great idea on paper.
