My wife and I will receive our 2nd Pfizer vaccine next week

It's a little nerve racking for someone my age because a friend who got his second shot of MRNA which is the new fangled way to defeat the original strain of covid that hit the U.S. last year in Pfizer and Moderna vaccines (the Astrazeneca and Johnson and Johnson are the more traditional way older vaccines function).

The friend I'm talking about who got I think Moderna (similar to Pfizer) got flu symptoms that we knocking him out the day we were talking to him on the phone. He had already gotten covid but he didn't have bad symptoms but his 40 year relationship partner passed away in Mexico when she went there for a visit in the last few months from Covid so this is terrible for him to deal with too.

However, we had to go several counties to the north beyond the Golden Gate Bridge to the north in order to arrange these two vaccines each. Also, we have learned that whatever vaccine you get you need to stick with that vaccine maker when you get boosters to address the variants in the future as well. Because each manufacturer is somewhat different in how they address all this because in some ways all the vaccines are NOT all the same either.

However, the most people that are NOT dying from covid are getting either the Pfizer and the Moderna vaccines at present (although all these variables could change at some point in the future). The point is you want to be one of the living and not one of the dead who don't get any vaccine simply because you have a 2.5% chance (every year) of dying from the covid or it's variants if you are not vaccinated.

And the way things presently look, this 2.5%  death rate from Covid is every year from now on because the variants just seem to be getting worse and worse, especially in places like Brazil now. But, here in the U.S. we also have the California Variant and the New York Variant and all kinds of other sub-variants starting as well now as well. 

So, the future is a complete unknown at this point and we are in a war for the survival of civilization I believe in the short and long haul of all of this because it appears we are going to lose more people than are being born worldwide ongoing for possibly now the rest of this century to coronavirus and to global Warming. This is what appears to be happening (at least for now). However, the future for mankind is an unknown at present whether any of us can fully survive this century here on earth. 

This is also true of all species on earth with us at this point too.

The point is that I believe now that my estimate of 1 billion people or less by 2100 AD here on earth  is accurate when I received this information shortly after 9-11 in the early 2000s.
