Ditto - what is "slight" or "very slight". Unless it's significant, and then "statistically significant", it doesn't amount to a lot.There is very low statistical confidence in the six week observation, so I think its best not to draw any conclusions until more data has emerged. So far the 1st and 2nd dose data it looking to be better than earlier data.
The initial news centered around "people don't have detectible antibodies after ____" without addressing whether or not there was an observation in significant levels of community sickness (as in an uptick in symptomatic covid cases, or even more important, moderate and severe).
Too little has been made of the fact that vaccinated folks and those who had covid already don't generally have symptomatic reinfection even when they no longer have detectible antibodies.
Reference back to the WA study which is likely at least 1.2MM person-months of exposure, and probably more than that. 100 proven cases, 10 hospitalizations, 2 deaths with a positive PCR, and hard to know if the deaths were with covid present or because of it. I'd bet much of that cohort was vaccinated earlier and toward the end of that, doesn't have detectible antibodies. Given that much of the cohort will be a very vulnerable segment of the population, I can't imagine how many complete basket cases would be in that group to begin with.
Just taking a whack at some statistics using the excel files from WA state, confirmed cases of covid (i'm guesstimating some) - 40k (vaccinated group is about 1/6th of the population), so normalizing the rest of the group and ignoring everything else (which isn't wholesome, but it's better than nothing), figure 100 vaccinated cases vs. 8000 per 1/6th slice of unvaccinated population)
deaths - 185 total (2 from vaccinated, or was it 3? assume 2). about 37 per slice (and on average, those slices are less vunlerable than the vaccinated slices - but who knows, maybe the vulnerable did more to avoid covid - too many variables to tell for sure, but 5 slices averaging 37 against 2 is stark)
hospitalizations - 10 for the vaccinated slice, 2678 for all others, or 536 per equivalent population slice vs. the 10.
If the data could be any better, I can't reasonably see how. Given the case load outside of the vaccinated population, it would be interesting to guess what the number of vaccinated cases would be if those folks didn't have to live among the unvaccinated. It would likely be very tiny.
