Excellent news it's so high. For comparison, MMR is 88% effective on Mumps

https://www.cdc.gov/vaccines/vpd/mmr/public/index.html#:~:te...

"One dose of MMR vaccine is 93% effective against measles, 78% effective against mumps, and 97% effective against rubella.

Two doses of MMR vaccine are 97% effective against measles and 88% effective against mumps."

Incidentally, mumps is something that is decreasing in prevalence because of coronavirus precautions. In normal times, 88% isn't quite enough for herd immunity to mumps and there are sporadic outbreaks. I (M35) got it last year even though I was vaccinated along with almost everyone from my age cohort and younger, and everyone significantly older is immune because they contracted it in childhood. But that outbreak which began in late 2018 went away very quickly in April-May 2020 [0]

Yes but those are near lifetime immunities. Not said (that I'm aware of) with these two covid vaccines is how long they protect for. If it is less than a year it will be very hard to get and keep people taking it.

Who cares?

The cost of getting a booster every year is minuscule compared to the number of lives lost, not to mention the hit to the world economy.

A working vaccine is a huge W. If immunity only lasts 12 months instead of 10 years that just decreases the font size down to 64 point from 72 point. I'll take it.

The virus is less than a year old.

The 5 year immunity level is not knowable.

Lifetime immunity doesn't make much economic sense. If you have a vaccine with people and governments from all over the world begging for you to sell it to them, vaccine as a service seems like a more efficient model than a one-time purchase.

I just got a SHRINGRX vaccine which is rated 97% effective. The second dose provoked a much stronger reaction, perhaps because I had some antibodies from the first.

Pope Benedict almost died of shingles in August.
