Back to the real world in NYC; time to get a real therapeutic against Covid going:
The study, published in the "Nature" journal on Tuesday, says BA.5 and BA.4 (15.2% of NYS cases on top of the estimated 40% associated with BA.5), are 4.2 times more vaccine-resistant than BA.2. Researchers said subvariant BA.2.12.1, which fueled the May case and hospitalization surge that sent 87% of all New York state counties into COVID high risk, according to the CDC, was found to be only 1.8 times more resistant.
According to the study, mutation at a key protein spike residue found in BA.5, BA.4 and BA.2.12.1 facilitates escape from some antibodies. The first two subvariants do have a mutation that compromises that ability to escape, but a reversion mutation "restores receptor affinity and consequently the fitness of BA.4/5," it says. Just one therapeutic antibody authorized for clinical use retains full potency against them, it adds.
We start the deaths again soon.
