Whenever things get worse they just come out with a quick easy fix called the vaccine..
I would not consider that the creation of mRNA vaccines were a quick fix; The underlying science behind mRNA vaccines goes back decades. We should be thankful that the technology to create mRNA vaccines had matured to a point where it could be useful for this particular situation.
We are ignoring two crucial things : one is declaring the truly preventative measures such as behavior modification and mask wearing including mask education and practical masking strategies
I must agree that wearing masks (and, in this application, N95 or equivalent) has been highly beneficial in limiting the risk of exposure to Covid and other airborne-based viruses. I completely endorse their use beyond our current situation concerning Covid. As our population increases and as our population density increases, we must be mindful that our actions (or lack of actions) have consequences. Mitigating such viruses with masking is a strategy that every population ought to take for a variety of reasons, including social and economic.
I have a pet peeve in that it is admitted vaccines do not prevent the disease so I really get upset at people who take vaccines but don’t mask up .. because contradiction in behavior and willingness to take a vaccine but not wear a mask for a mutating disease, I can’t help but believe vaccines can give a false sense of security for people to go maskless .. if vaccines don’t prevent long covid nor the spread of covid then that’s seriously bad in the long run.
My understanding is that the vaccines were never intent on limiting spread but only reducing the degree of which someone suffers from Covid once they were infected. A combination of masking, vaccination and behavior modification (such as avoiding large crowds when possible) is the best-known strategy for limiting the spread of any airborne-based virus, Covid or otherwise.
What is the likelihood of a new variant coming out just about the time everybody gets the latest booster/vaccine?
No one knows when the next prominent Covid variant will emerge or exactly why. This uncertainty makes taking the precautions that are available to us that much more important. We have seen so far that Covid continues to progress and our vigilance needs to continue until the mortality numbers are so low as to be indistinguishable from random occurrence.
