The problem is you can try and pinpoint flaws with a lot of the current recommendations with any small spike and say--oh well its all "useless" not seeing the forest for the trees.
We already have data for what happens when you don't do any social distancing or masks--Sweden vs the rest of Scandanavia.
Even a crude mask study in bangladesh
We can easily compare countries on vaccination rates.
We have data on millions in unvaccinated vs vaccinated, hospitalization/death rates, in several countries.
Yes you can still go to the hospital or die of COVID if you get vaccinated--it is not 100% effective. However the alternative odds are much much worse.
What is happening--is the anti-vax/any health recommendations crowd are either misusing or making up data where there is not the detail they are claiming (Wales)
Confabulating completely where there is bad/anecdotal data (india)
Pointing out small spikes to say it isn't working (Israel--but that was a vaccine immunity fading issue with Pfizer--which they reversed)
And pointing out the small spike in Israel vs Sweden- which on the whole is still doing loads worse per capita deaths/hospitalizations, etc on every measure than Israel, despite being richer.
So yes the Pfizer, and to a lesser extent Moderna fade--but we knew this going in as we made the choice to go with shorter dosing intervals rather than 4-5 mo between doses. While this for sure saved lives and hospital visits--it will also mean people will have to come back for boosters.
There is no conspiracy to any of it--several vaccine experts said at the time this is sub-optimal dosing schedule and we will have to see how long immunity lasts.
I am willing to bet almost anything we will see pockets of spikes in highly vaccinated areas. More likely than not it will be the vaccine immunity fading for vulnerable groups who also got shots first. Nowhere in the US has 100% vaccinated - so we could see a spike--and it could be the small percentage of unvaxxed driving a large part of the spike. Our data collection is not as good as centralized heath providers but we can assume similar things will happen as we see elsewhere.
We see unvaccinated driving new deaths and hospitilzations in Israel who keeps good data 17% of unvaxxed driving 50% of new deaths and 66% of serious cases.
https://www.haaretz.com/israel-news/covid-israel-unvaccinated-17-nearly-half-deaths-booster-pfizer-1.10216067 They have age cohort and vaccine status--its pretty telling:

This doesn't mean something doesn't work or we were lied to. We did sub-optimnal time between doses to stop deaths and hospitalizations and it worked. Again take the behavior and stats as a whole--those areas are doing much better than less vaccinated areas. And Israel has great data and fast recovery showing what a booster campaign can do (for those that take it).
