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
4) Here are the official eligibility criteria for boosters. Note that Moderna as a booster is a modified 50 mcg. Normal first 2 shots of Moderna is 100 mcg.
5) that said, if you have a cancer or immunocompromised like #MultipleMyeloma, then you should go with the Moderna full dose 100 mcg two shots. Ask your doctor if still possible.
6) Moderna 2 shots (2x 100 mcg) yielded 6x greater antibody response than 2 shots of Pfizer. Might be too late to change; but just FYI for those not vaccinated yet.
7) This booster study (top post) is funded by the NIH. Though keep in mind the Moderna “booster” they tested was the 100 mcg full dose, and not the 50 mcg currently FDA authorized Moderna booster. So while Moderna looks strongest, keep in mind it’s 2x the current booster dose. Image
8) The study hold a wealth of data on boosters. Really key is that J&J seems to lag all the other boosters in terms of antibody response. medrxiv.org/content/10.110…
9) What does booster offer) more than 90% risk reduction in SEVERE DISEASE in Israel 🇮🇱 for those who got 3 Pfizer doses versus 2 doses after 6 months!!! And it benefits both elderly and younger adults!!! Middle age should definitely take booster! Image
10) This is what happens when nationwide boosters were rolled out in Israel 🇮🇱. Its Delta variant wave stopped soon after. Image
11) good morning - 100 million at risk Americans can likely get boosters starting today.
12) Forgot to mention - it seems having initial Pfizer doses then switching to Moderna has slightly less severe headache, fatigue, nausea, and myalgia than a 3rd Pfizer dose.
medrxiv.org/content/10.110… Image
13) Unpopular thing to utter aloud — but many scientists think 1 dose J&J is way too weak. It should never have been a one dose vaccine in the first place. 2 dose should have been minimum.
14) Even 2 doses of J&J is much weaker for T cell stimulation versus 2 Pfizers.
15) What is better than figuring out which booster to get? GOING OUT TO GET ONE! see thread 🧵 of evidence 👇

🛑CANCELLED—“Research on Women’s Health” funding website of the NIH. Image
2) here is the page that is now deleted. Funding opportunities in women’s health research of ORWH site. Didn’t Trump say they at least recognize women as a gender? Weird.

3) It’s a bloodbath today for CDC websites too…

🪓DELETION UPDATE—More than 1,000 pages are now deleted from websites of CDC, National Institutes of Health, and other sites of the Department of Health and Human Services, according to a new WSJ analysis—including many **vaccine recommendation** scientific pages! Image
2) CDC’s vaccine advisory committee webpage… now ❌ DELETED ❌ Image
3) To be clear, while the main ACIP website is still up (generic committee info), the “VACCINE SPECIFIC RECOMMENDATIONS” website of ACIP has been **deleted**. That key page is the one with the actual public health info for vaccines. Feel free to verify:

⚠️CDC WEBSITES DELETED—Multiple CDC websites and datasets related to HIV, LGBTQ people, youth health behaviors and more have been removed after the agency was directed to comply with an executive order from President Trump by 5pm deadline. Wildest is taking down even HIV pages! Image
Image
2) Like, why then hell did the “CAUSES” of HIV even get deleted??? Makes zero sense. Why is Trump WH wanting to block how to stop HIV???
cdc.gov/hiv/causes/ind…Image
3) also deleted: CDC’s Youth Risk Behavior Surveillance System, which includes data from a national survey, has disappeared. so have parts of the Agency for Toxic Substances and Disease Registry’s Social Vulnerability Index and the Environmental Justice Index.

⚠️Do you wonder why you haven’t heard much about this massive TB outbreak recently? Cuz the CDC can’t hold any press conferences or issue public statements of any kind.

➡️Most of the world 🌎 has been vaccinated against TB… but the US has not, which is now extra vulnerable. Image
Image
2) For those asking, the majority of the world has used the BCG vaccine against TB… the BCG vaccine also protects against many other bacterial infections too. Up until now, CDC skipped it because US was low risk, and the BCG vaccine leaves a small scar & BCG messes up TB tests. Image
3) What about drugs for TB? Yes they exist but the problem is that TB often develops drug resistance (the bacteria evolves to evade neutralization). And thus, multi drug resistant TB has become a worldwide issue. That’s why childhood vaccination better.

⚠️PFAS IS BACK—recall the EPA plan to ban dangerous forever chemicals from drinking water ➡️Well, Trump WH just cancelled it… once again allowing big corporations to discharge PFAS into rivers. PFAS cause cancers & many diseases. Does this make American healthy again? Image
2) “There really isn’t a system within the human body that isn’t affected by PFAS. They are toxic in many ways, but they’re also very long-lived. They’re designed not to break down in the environment or not to break down to heat and chemical stress.”
michiganpublic.org/politics-gover…
3) CDC also just got banned from seeking any advice or input from the WHO — CDC can’t communicate or even enter any WHO building anymore. Perfect way to politically isolate CDC from outside science.

3) It also says @CDCgov staff are not allowed to visit @WHO offices.
