Covid Variant Omicron (B.1.1.529)

In summary: There's an "extremely high number" of mutations in this variant, some of which could make it more transmissible or undermine the effectiveness of vaccines. UK Health Secretary Sajid Javid has announced that six African countries will be added to the UK's red list from tomorrow at noon local time. Flights from South Africa, Namibia, Lesotho, Botswana, Eswatini and Zimbabwe will be temporarily banned and UK travellers will be required to quarantine.This variant stands out because it contains more than 30 changes to the spike protein - the SARS-CoV-2 protein that recognizes host cells and is the main target of the body's immune responses....

Thanks. I don't see it there. Probably I'm a little too early. The numbers here in the Midwest are still pretty good. I've several friends who got a few bad days from the second booster so I think I'll make it count... will post if I find out

From last week -

Moderna (June 22) - "Moderna released study results today showing its new Omicron-specific booster increased antibodies against the coronavirus by a factor of 5, even against some of the newer and more worrisome variants."
The company also today said it will soon ask the FDA to authorize the use of the vaccine. The company said shipments of this vaccine could begin as early as this summer.

June 25 - Pfizer says its tweaked COVID-19 shots boost protection against the omicron variant​

My understanding is that the new boosters (2nd booster tweaked for Omicron variants) would be available by August/September. The FDA recent approved vaccines for children under 5, and the government has been pushing out vaccines for children 5 to 11, and now for under 5 population.

In mid-June, the Food and Drug Administration (FDA) granted emergency use authorization (EUA) to Pfizer's COVID-19 vaccine for children ages 6 months to 5 years, as well as to Moderna's vaccine for kids ages 6 months to 6 years.Jun 19, 2022

The Food and Drug Administration is expected to authorize new COVID-19 booster shots this week that target the latest versions of the omicron variant but will do so without data from a study showing the shots were safe and worked in humans.

Clearance of the doses, without data from human testing known as clinical trials, is similar to the approach the FDA takes with flu shots, which are updated annually to keep up with mutating flu viruses, as the Wall Street Journal reported.

“Real-world evidence from the current mRNA COVID-19 vaccines, which have been administered to millions of individuals, show us that the vaccines are safe,” FDA Commissioner Robert Califf said in a recent tweet.
