DELAYING 2nd DOSE RISKY—

🇬🇧 SAGE warning:

Delaying doses of coronavirus inoculations will increase the chances of a vaccine-resistant strain of #COVID19 emerging, government scientists warn. 🧵
independent.co.uk/news/health/co…

2) Sage scientists there was an “increased risk of virus replication under partial immunity after one dose than after two doses, so in the short term, delaying the second dose would be expected to somewhat increase the probability of emergence of vaccine resistance”

3) Is such an increase material? It is not currently possible to quantify the probability of emergence of vaccine resistance as a result of the delayed second dose, but it is likely to be *small*. The UK currently has limited supplies of vaccine.

BREAKING—Trump FDA just left final kick in the teeth—Pfizer will now ship fewer #COVID19 vaccine vials after it lobbied to count & **pay for** “extra” doses found in vials. Now Pfizer can count 6 per vial to meet dose orders—ie shipping less vials. When FDA approved? Jan 6th! 🧵

2) “For weeks, Pfizer execs pushed officials at Trump FDA to change the wording of vaccine’s emergency use authorization so it formally acknowledged that vials contained 6 doses, not 5. Distinction critical: Pfizer’s contract requires paid by the dose.”
nytimes.com/2021/01/22/hea…

3) “Now, it appears, the bill is due. Pfizer plans to count the surprise sixth dose toward its previous commitment of 200 million doses of Covid vaccine by the end of July and therefore will be providing fewer vials than once expected for the US.

BREAKING—UK 🇬🇧 Prime Minister Boris Johnson says: Early evidence suggests the #b117 variant of #covid19 that emerged in the UK may be more deadly. (data assessed by scientists on New and Emerging Respiratory Virus Threats Advisory Group). TO BE UPDATED. bbc.co.uk/news/health-55…

2) Early estimate: 30% more deadly.

Johnson said: "In addition to spreading more quickly, it also now appears that there is some evidence that the new variant—the variant that was 1st identified in London and the south east - may be associated with a higher degree of mortality.

3) "It's largely the impact of this new variant that means the NHS is under such intense pressure."
The evidence comes from mathematicians analysing trends in the numbers of people dying with the new and the old variants.
