In today's hearing @US_FDA on @pfizer request for approval of 3rd #COVID19 #booster #vaccine the company presented data on its original 2020 study volunteers, many of whom originally got placebos. All those people were eventually given 2 doses of vax, but months after the..

2/...matched study pool that was vaxed from the start. This created a staggered time set for looking at duration of immunity, and then comparing impact of giving all of them a 3rd dose. They looked at protection against original (WT) form of #SARSCoV2 & beta (SoAfrica) type.
MORE
3/ The @pfizer conclusion is that #vaccine efficacy definitely wanes over time, a 3rd dose works to boost it, said dose is safe and powerful. Company said 1.8 million more cases of severe #COVID19 wld occur in USA this year w/out 3rd dosing.
MORE
4/ The @US_FDA scientists reviewed all @pfizer data & presented their analysis to expert panel, generally agreeing with the company's study results. But it's noteworthy that the FDA's JooHee Lee never said anything about needs assessment -- Does America NEED a 3rd dose?
MORE
5/ This afternoon there will be public responses and then tough questions from the expert panel. Sometime around 4:30-5pm the @US_FDA advisors will take a formal vote. Next week the ACIP @CDCgov will also review 3rd dose issues. And then a formal FDA decision will be issued.

Big news from Laos @PasteurVirology relevant to the origins of #SARSCoV2:
"our results pinpoint the presence of new bat sarbecoviruses that seem to have the same
potential for infecting humans as early strains of SARS-CoV-2."

collectors, or certain ascetic religious communities who spend time in or very close to caves, as well as

Hearings today @US_FDA on @pfizer application to give 3rd doses of #COID19 #vaccines . Much rests on the Israeli findings. Two reps of their MOH presented details, which are significant because Israel's mass vax is abt 3 months ahead of Europe & UK & USA.
MORE
2/ Israel 1st rolled out mass vax in December, and the impact against routine forms of #COVID19 was excellent. It seemed that a standard @pfizer #vaccine protocol worked beautifully.
BUT, MORE
3/ But then, Israelis told @US_FDA , the #DeltaVariant slammed Israel and #COVID19 incidence in all age groups, including among fully vaccinated, soared. The question was why.

Scientific advisors @US_FDA are meeting today to decide whether @pfizer 3rd dose #COVID19 #vaccine booster should be approved. Sarah Oliver started, from @CDCgov , laying out grim current epidemic situation in USA.
MORE
2/
 the @CDCgov Oliver showed that there was a tremendous uptake of #COVID19 #Vaccination in the USA in April, which plummeted by June and is crawling back now. Overall, vaccine uptake is the paramount problem.
MORE
3/ Because #COVID19 #vaccination rates in America remain disappointing, COVID hospitalizations are soaring. And unvax'ed people under 65 are 22 to 23 TIMES more likely to be hospitalized versus those who have received vaccines. The difference is astonishingly huge.

OK, ENOUGH ALREADY.
Here's the #Ivermectin saga, people.
1.) In the 1960s Japan's Satoshi Omura did chemistry work, trying to find a medicine to kill helminth worms in livestock.

4.) Omura discovered a bacterium that emitted a powerful anti-helminth chemical.
5.) William Campbell @Merck tested it. Using synthetic chemistry, they made "ivermectin" -- 25Xs stronger than the bacterial chemical.

5.) The @Merck & Kitasato companies were thrilled to discover it cured a long list of livestock worm & parasitic diseases & a huge veterinary market opened.

ICYMI 3 excellent graphics from @TheEconomist comparing immune responses with & w/out #vaccines to alpha vs #DeltaVariant #SARSCoV2.
First, efficacy dropped in UK for both @AstraZeneca & @pfizer vaxes against Delta, once it took over the #COVID19 landscape.
MORE
2/ When the UK switched from alpha #SARSCoV2 to the #DeltaVariant dominating the #COVID19 landscape, the key change was in the ability of @AstraZeneca or @pfizer vaccines to prevent infection.
MORE
3/ Curiously, in the UK when UNvaccinated folks got re-infected with alpha #SARSCoV2 they mustered weak antibody responses, despite prior exposure. But with #DeltaVariant a 2nd infection in unvax'ed people elicited a BIG antibody response. Why? Who knows? Merits study.

Many #COVID19 #vaccine refusers say there's "something" in there -- a transmitter @BillGates uses to monitor us, magnets, 5G signalers.
Let's take a look:
1.) Whatever "it" is must be small enough to pass thru a 0.152 mm (aka 0.0035 inch) wide hole at the tip of vax needle.
MORE
2.) It must be powered somehow.
3.) and it should last a long time to be worth the cost & trouble.
So, how does that stack up with reality?
World's smallest battery is 150 nanometers, but doesn't last long -- minutes. Tiny 3.5 mm lithium batteries work, but that FAR too big.
MORE
World's smallest transmitter is 5 by 9 by 4.8 mm in size, transmits up to 120 meters, requires a 1.5V battery.
Too big.
Smallest Bluetooth transmitter runs on 0.6 milliwatt battery but needs a 14 mm antenna.
Too big.
And any transmitter needs a microphone --
