Some of the hundreds of subvariants being tracked by WHO are already in the U.S. and Canada with BQ.1.1, BQ.1, BA.2.75.2 and XBB increasing in numbers. Those Omicron subvariants are able to sidetrack much of the immune defense that previous vaccines were upholding to a great degree.
"It's like a whole bunch of horses in the race at the moment and they've each gathered these different mutations," said Sally Otto, a University of British Columbia evolutionary biologist and virus modelling expert at the Coronavirus Variants Rapid Response Network. That means it's playing a different game, it's evolving in different ways and that is to masquerade from our immune system."
Everyone needs to get the word out to friends and family AND on social media to get the bivalent vaccine as it has 2 different strains it can help defend against. (as well remind about the flu vaccine! Our diligence with increased cleanliness and personal hygiene, space and masks has kept it at bay, but this year people are letting all of their defenses down, sadly)
I have diligently been reminding my family and friends and they will be totally vaxxed and boosted up by the end of the month. Sure those who tried to pooh pooh needing it find me annoying, but they know I want them around for many more years to come.
