I'm not an anti vaxxer. I've had my vaccine and the booster and I encourage everyone to do so... But as you say... It only slows the speed... Us that have been vaxxed can still catch it and spread it and as long as that's true it's only going to continue to mutate. Sometimes I think us vaxxers may be helping it spread... While we can still catch it, we don't get as sick and die and sometimes show no symptoms at all.... We can walk around spreading it without even knowing we have it... The next few years will be interesting....
