So far we have had between 4 and 6 waves a year, each of which is from a different variant. A variant breaks out and within 2 months its infected almost everyone at which point it dies down to become part of the background infections and a new variant takes over. There just isn’t enough time to make a vaccine and roll it out to deal with any of that problem. The vaccines that are getting rolled out now are for variant that disappeared 6 months ago. Nothing we do is going to be very effective against this until the vaccines are a lot more effective against potential future variants or we drastically reduce the number of hosts it gets to replicate in.
