I am saying that - as we look at the history of vaccines - we can see that they are only really needed in areas where there are outbreaks of a virus. Thus in just a few years, a wealthy country like the US could eradicate most outbreaks, if not all of them, if more people would take the shot, keep the virus from spreading, and the political propaganda were not so powerful among the less educated. Outbreaks can still be introduced in the US by those from - say - India, who bring the Delta variant with them. There will be other variants of the virus, and likely new vaccines to address them. The COVID19 virus may only last in 1st world countries for a few more years, with minor outbreaks, but that's not known at this point. One can look to the history of vaccines in order to see how long they've lasted. We might worry, for example, about the next SARS outbreak, rather than COVID19. I would agree with any conspiracy theory that locates the intentional spread of the virus to a COVID lab in Wuhan. In my view it's biological warfare that serves China's government and the .01%, hence the US would never admit this. But I could be wrong. My view is that we should follow the money.
