washingtonpost.com/health/2021/10…
3) And someone who has been fully vaccinated with Moderna could get a booster with Johnson & Johnson or Pfizer, if they are older than 65 or older, or at high risk.
4) The booster shots could start to be given by the end of the week, pending a meeting of CDC advisers and a decision by the agency’s director, Rochelle Walensky.
5) The CDC’s Advisory Committee on Immunization Practices is likely to provide more detailed guidance and recommend that individuals try to get a booster of the same vaccine as their initial series, but allow for mixing and matching, according to federal health officials.
6) Get the booster… here is how to pick.

📍BAD SIGN—Something really bad happening in UK 🇬🇧—especially notable in Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿— where hospitalization for #COVID19 resurging—but for first time since vaccine mass rollout—deaths newly spiking now as well ⚠️. Possibly new Delta sub variant. Watching. bbc.com/news/uk-wales-… ImageImageImage
2) in the UK, there has been a sudden rise in a Delta subtype AY.4.2, which some are calling "Delta Plus", contains mutations that might give the virus survival advantages. It’s about 10% now. bbc.com/news/health-58…
3) this new surge seems unique to UK and Eastern Europe at the moment. Russia is now in a one week semi lockdown, as is Latvia. UK may need fast action to avoid that fate.

BEST BOOSTER? Mix it up — but depends which you had first. Switching vaccine for the booster seems to be the best—Pfizer to Moderna booster, Moderna to Pfizer for booster, and J&J should switch to Moderna / Pfizer booster. HT to @ScientistSwanda. #COVID19 #BoosterShots #vaccinate Image
2) Vaccine efficacy and booster eligibility summarized here by @MedicalLetter. secure.medicalletter.org/downloads/1621… Image

ERADICATION?—oh hey… Historically low global flu rates during the pandemic may have eradicated one flu type—1 of 4 flu viruses that infect humans each year hasn't been detected anywhere in the world since April 2020➡️ zero worldwide in 18 months! Hopeful.

Explosion of new #COVID19 cases across Eastern Europe & UK. Surge so high that Latvia is forced into lockdown, and Latvia health minister blames “disinformation” about vaccines in Russian-language media for vaccine skepticism. New wave possibly restarting.
theguardian.com/world/2021/oct… Image
2) Last week, Latvian president tested positive, forcing Finland’s president, who had met Levits a day earlier, to self-isolate. Latvia was for a long time viewed as one of Europe’s few COVID success stories—fewer than 3,000 Covid deaths since the start of the pandemic.
3) Latvia health minister Pavluts said there was "disinformation" about vaccines in Russian-language media.
"To address the disinformation in Russian, we are doubling our efforts on the information campaign, everything will also be translated in Russian,"
