Sub-variants BQ.1.1 and BQ.1 account for near 70% of the variants and BA.5 has declined to 11%. XBB is at 4.7% (CDC data); how then, would the bi-valent booster work? Rochelle, here's your answer!
by Paul Alexander
The bi-valent booster will be a mismatch (and is a mismatch) for BQ.1.1 and BQ.1 and XBB etc. I think this was done to sell Wuhan vaccine etc. CDC & NIH & FDA & Pfizer know booster will drive variants
See the Variant Proportions as of today as reported by CDC. We see that BQ.1.1 and BQ.1 account for near 70% of the variants and BA.5 has declined to 11%. XBB is at 4.7%.
