The bottom line on vaccine efficacy against #COVID19 variants, as well as comparing one vax to another:
ALL of the vaccines are still more effective vs all strains of covid than the flu shot is vs flu strains in many years.
And 50% more likely to live still better than 0%!

We can’t allow our collective judgements to be clouded by the amazingly high (and to be frank unexpected) 90% plus efficacy of the mRNA #COVID19 vaccines against the original viral variants.
The original bar for most scientists as well as @US_FDA was > 50- 60%.
The original bar for most scientists as well as @US_FDA was > 50- 60%.
In other words, judged by original/ pre- mRNA standards, the current efficacy of all the current vaccines against all the current strains would’ve been widely touted and welcome news if they’d been the first across the finish line/ to get authorization.
As to should you wait for the “best vaccine,” my answer is “ABSOLUTELY NOT!” Herd or community immunity (which is how we ultimately stop the pandemic) is additive. The longer we wait to get you & everyone else some protection, the longer this all longer on. So get your vax ASAP!
And finally, no vaccine was ever going to be 100% effective against any variant. We can still stop the pandemic with a ~60% effective vaccine- IF enough get it. But the longer we wait to give everyone SOME protections the more time the virus has to mutate and escape completely.
