Also, we saw your post earlier, @David in FL, but it's as dumb the second time as it was the first time.
In addition to what Dan said above, here is another article from the WHO:
The effects of virus variants on COVID-19 vaccines
The text in bold is quotes from that article:
The COVID-19 vaccines that are currently in development or have been approved are expected to provide at least some protection against new virus variants because these vaccines elicit a broad immune response involving a range of antibodies and cells.
How can we prevent future new variants of the COVID-19 virus?
Stopping the spread at the source remains key. Current measures to reduce transmission – including frequent hand washing, wearing a mask, physical distancing, good ventilation and avoiding crowded places or closed settings – continue to work against new variants by reducing the amount of viral transmission and therefore also reducing opportunities for the virus to mutate.
Scaling up vaccine manufacturing and rolling out vaccines as quickly and widely as possible will also be critical ways of protecting people before they are exposed to the virus and the risk of new variants.
Why is it important to get vaccinated even if there are new variants of the virus?
Vaccines are a critical tool in the battle against COVID-19, and there are clear public health and lifesaving benefits to using the tools we already have. We must not put off getting vaccinated because of our concerns about new variants, and we must proceed with vaccination even if the vaccines may be somewhat less effective against some of the COVID-19 virus variants.
So the scorecard:
Are nearly 100% protected from the majority of strains/variants of COVID-19.
Are "somewhat" protected against every variant of COVID-19.
Have a very low chance of catching COVID and an even lower chance of passing it on to someone.
Are helping to reduce the creation of new variants.
Aren't protected at all against the majority of strains/variants of COVID-19.
Aren't protected against any variant.
Have only a reduced chance of catching COVID-19 because other people are being good members of society and getting vaccinated.
Are not helping to reduce the creation of new variants.
Your "we don't know how the vaccine handles new variants" is a bullshit excuse not to get vaccinated because every vaccine out there is more effective against every variant than not getting vaccinated at all. You're being selfish while conning yourself into thinking you're being "prudent." Nobody would rationally define "prudent" the way you're choosing to. Nobody who understands the mountains of data out there. What you are calling "prudent" is what most may call "selfish."
