SARS-CoV-2 Variant HV.1; Obsolete Boosters

 As previously covered, the currently available FDA emergency use authorized "Booster vaccines" were designed based on recommendations developed at the FDA VRPBAC, which predicted that the dominant SARS-CoV-2 variant this fall would be the "Kraken" viral variant of Omicron.

Which brings us to the present, and the new SARS-CoV-2 variant with the "Pango" designation of HV.1.

Getting back to HV.1, what are the new mutations and why should you care? Are we all going to die, as a certain veterinarian scientist keeps predicting? Well, yes, that is generally how things work, but most likely not from this or any other variant.

As we move into the thick of respiratory virus season, there's a new COVID-19 variant to keep your eye on: HV.1.

Now, the variant causes nearly 20% of all COVID-19 cases in the country.

"HV.1 is another Omicron XBB variant that has descended from EG.5," he says.

HV.1 shares almost all spike mutations that EG.5 carries, including F456L. However, HV.1 has one surprising additional mutation: L452R. The L452R mutation, which increases infectivity, is one of the key mutations of the delta variant in 2021 but is absent in the Omicron variant.
