a couple caveats on the promising pzifer vaccine:

above all, it's clearly very encouraging news, even if the testing isn't complete. better efficacy than we would have happily settled for in such a short time frame (even though it feels like it's dragging on forever, this is lightning speed for vaccine development).

first, it requires two doses, three weeks apart. so, not an instant fix.

second, it needs to be kept cold constantly from manufacturing until injection. manageable for developed countries like america, but not so good for many countries across the world, which in turn means the virus will be around for a while even if once it's under control here at home.

third, it will take months to complete the testing and ramp up manufacturing and distribution, and get people to take the doses, and then for the actual number of active cases to drop to safer levels. part of the protection of a vaccine is that the person who gets it is protected (but only 90% in this case) and part of the protection is lower exposure risk because other people are less likely to have it as they get the vaccine as well (herd immunity). it will take more time even after you get your shots for the herd immunity part to kick in.

They could run some tests at -5 and I imagine they would get months. In the US at least we can ship down to -20 easily (UPS, Fedex).

pharmacies, and doctor's offices. That was an original concern for the varicella vaccine, which fortunately turned out to be more in line with storage issues for other routine vaccines. But, the mRNA vaccines are going to be extremely termperature sensitive.


Not to mention we know way too little about longevity of protective antibody. So, yes, it is a positive report, but PH officials are correct in saying a mask with distancing still remains one's best protection and will for a long time to come.

Regarding our best protection for now, I would say it the other way around: Social distancing, with masks. An unfortunate effect of the big push for mask usage is that people get the impression is that is all it takes. Masks help, but social distancing is the key.

We have to get through the winter and spring of '21 by continuing social distancing and public hygiene measures.

We also have to pass economic support measures for the unemployed and to continue keeping businesses out of bankruptcy. But we now have a good handle on how large those have to be and how long they must continue.

We also need to think about what the "new normal" economy looks like once Covid is suppressed. It won't be like the economy of 2019, since many changes are irreversible.

they looked at
a) the total number of cases among the people who got the vaccine and compared it to
b) the total number of cases among the people who got the saline injection (placebo).

and i'm guessing a) was 90% less than b)


no idea if it's more sophisticated than that, e.g., do they try to control for level of interaction with strangers, hours outside the house, hours in enclosed areas with strangers, whether they wear a mask appropriately, etc.

there's always some uncertainty in these tests as you never know exactly how the individual subjects behaved "in the wild".

There's some confounding factors here. Such as, the group chosen as subjects from the pool of applicants as a whole were all probably already extremely COVID proactive and therefore more likely to follow the existing protocols 'in-the-wild'.

I'm sure the disclaimer to continue the existing protocols will be added in the fine print, if and when, this vaccine is finally distributed. Oh, well... At least half of the population will potentially be better off, excluding the Trumpanzees and Loser45 himself. A bright spot!

there's no way by just looking to tell if somebody has been vaccinated. Less mask-wearing means more risk of getting the virus for the non-vaccinated.

and masks are reportedly about 75% effective. so if people get an 80-90% effective vaccine but then stop using the 75% effective mask, the improvement isn't nearly as much as it would be if people continued (or started ffs) wearing masks until the number of active cases dropped to very low levels.

The goal of operation "Warp Speed" did was to cut out the ramp up for manufacturing.

38. Pfizer "warp speed" agreement with US gov occurred on July 22.
Mon Nov 9, 2020, 11:20 AM
Nov 2020
NEW YORK & MAINZ, Germany--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced the execution of an agreement with the U.S. Department of Health and Human Services and the Department of Defense to meet the U.S. government’s Operation Warp Speed program goal to begin delivering 300 million doses of a vaccine for COVID-19 in 2021. Under the agreement, the U.S. government will receive 100 million doses of BNT162, the COVID-19 vaccine candidate jointly developed by Pfizer and BioNTech, after Pfizer successfully manufactures and obtains approval or emergency use authorization from U.S. Food and Drug Administration (FDA).

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20200722005438/en/

The U.S. government will pay the companies $1.95 billion upon the receipt of the first 100 million doses, following FDA authorization or approval. The U.S. government also can acquire up to an additional 500 million doses.

Americans will receive the vaccine for free consistent with U.S. government’s commitment for free access for COVID-19 vaccines.

Mon Nov 9, 2020, 11:39 AM
Nov 2020

At the time of the agreement, Pfizer and BioNTech were gung-ho.

We are pleased to have signed this important agreement with the U.S. government to supply the initial 100 million doses upon approval as part of our commitment to address the global health threat. This agreement is one of many steps towards providing global access to a safe and efficacious vaccines for COVID-19. We are also in advanced discussions with multiple other government bodies and we hope to announce additional supply agreements soon. Our goal remains to bring a safe and effective COVID-19 vaccine to many people around the world, as quickly as we can,” said Ugur Sahin, M.D., CEO and Co-founder of BioNTech.


I expect that Pfizer would not lock themselves into such an agreement, and at some point, might have determined they would be better off by selling on the free market.

Pfizer would do themselves no favors by discrediting the US governments efforts to accelerate vaccine development. I expect we will hear more about this.

EDIT TO ADD: Looking at the words of the announcement, this might be a key phrase:

The U.S. government will pay the companies $1.95 billion upon the receipt of the first 100 million doses, following FDA authorization or approval. The U.S. government also can acquire up to an additional 500 million doses.


So the agreement might be a guaranteed purchases at some agreed-upon price. This would help Pfizer in financing for the manufacturing ramp-up, but technically they would have received no money. I certainly hope Pfizer would not make this claim.
