Natural immunity is far superior to vaccine generated immunity...
Good… the FDA is doing its job in this instance. I’m not sure that Prfizer’s vaccine is losing some of its efficacy because of the lapse of time or just because it’s simply not as effective against the Delta variant. The Mayo Clinic study showed that the Pfizer vaccine was 42% effective (compared to unvaccinated individuals) at preventing detectable infections once Delta became dominant while Moderna still retained 76% efficacy in the same time period. That might mean that Pfizer is simply less effective against Delta regardless of the recency of vaccination so a third shot might not offer much improvement.
Fortunately both vaccines continue to offer good protection against Delta when it comes to hospitalization and death.
Didn’t they go forward with unverified data before?]
