Originally posted by lesmore49 Thing I'm struck by is insofar as Covid, vaccination, do we need to, do we not need to take measures, how long do the vaccines last (6 months I heard today), do we need the booster within 3 weeks (Pfizer)...etc. or not. For all our science, specialists, the fact that covid is relatively new....there doesn't seem to be a lot of definite, 'for sure' knowledge about the ramifications, herd immunity, etc.
Nothing seems sure in life, and well being a septuagenarian, one lesson I've learned in this life of ours, on this planet of ours....is there is nothing guaranteed in life.
In my everyday life, I do proceed cautiously, use a mask, carry hand sanitizer, don't go to crowded venues, mostly stay in, with exceptions of daily walks in uncrowded areas. I'm retired, live in an uncrowded suburb, have the means to order groceries, etc. online and have all this delivered to my door....so have the luxury of maintaining a cloistered life, but my observation is that many do not not. Many are out there working, shopping in stores, while trying to keep appropriate distance, etc.
Looking at numbers, Covid seems to mostly affect those who are older, the probability seems to be that they live in seniors' homes and not that well, mostly from other conditions. The way many countries in the G7 deal with Covid, is lets be safe rather than sorry, and I don't have any issue with that, except is there a light in the covid tunnel, a light where we will eventually live, a 'normal' life, a life without masks, social distances, etc.
So, I remain,
One confused fellow.
I think the data is becoming clearer over time.
How long do vaccines last? As you say, this isn't totally clear. Based on antibody levels we would say at least two year, maybe longer. The issue really isn't the antibody levels though, it is variants. So, something like the UK strain (B.1.1.7) or Brazil strain (P.1) are not dealt with as easily by antibodies to the original strain and could require a tweaked vaccine. Vaccine protocols are probably not a huge deal -- that is it probably isn't really that important if you put 3 or 4 weeks or 12 weeks between doses of the vaccine. If you are seeing big spikes in cases, it probably makes sense to get as many people a first dose and space out the second dose a bit.
The places in the United States that are seeing growing numbers are places where the B.1.1.7 has arrived. Those would be Michigan and Florida, followed by other states.
As others have mentioned, the data out of Israel looks wonderful. They are down to 400-ish new cases a day and only 8 deaths a day. This in a country that is similar in size to Michigan (Michigan is averaging 7000 new cases a day and 45 deaths a day) -- the big difference being that Israel has been able to vaccinate a high percentage of their populace.
