5) we don’t think it’s more severe or lethal of a variant. But a more contagious one will harm more people than one that is only more severe. Nature of exponential growth.

Breaking—India approves its first 2 #COVID19 vaccines—Oxford/AstraZeneca vaccine and a locally developed vaccine by Bharat Biotech, called Covaxin, still in Phase 3 and not published efficacy data yet, but “the vaccine has been found to be safe.” nytimes.com/2021/01/03/wor…
2) approvals were announced at a news conference in New Delhi on Sunday—the decision to approve both vaccines came after “careful examination” of both by the Central Drugs Standard Control Organization, India’s pharmaceutical regulator.
3) “Indian regulators are still considering approvals for other vaccines. One, made by Pfizer and BioNTech, has already been approved in the United States and Europe. Another, Russia’s Sputnik V, appears to be less far along.”

Huge—the #SARSCoV2 coronavirus was identified in a 4 year old in Milan 🇮🇹 in November 2019, and had *no travel history*. They retested it again and again to make sure. This moves back the date of first 🇮🇹 case by ~3 months, and corroborates wastewater positive tests too. #COVID19
2) In December 2019, Milan and Turin 🇮🇹 both found #SARSCoV2 in their wastewater. This earlier study from June. People weren’t sure what to make of it, and there was no proof of human infection that long ago. But now there is proof^
3) This also corroborates the coronavirus was in the US 🇺🇸 blood supply in mid Dec 2019, according to CDC analysis.

📍Worrisome new data—new B117 variant is not only more infectious, it’s potentially more infectious in children 0-9 (+24%) and 10-19 (+14%), and less among 60-79, compared to common strains. More sobering—the R estimate is much higher.

THREAD🧵 #COVID19 imperial.ac.uk/media/imperial…
2) For R, various estimates range from 0.36 to 0.68 (higher R via more accurate sequenced virus samples, lower R estimate via shortcut PCR test w/ more data). This means every person infected w/ B.1.1.7 variant **infects additional +0.36 to +0.68 persons** than old strain. Wow.
3) To be clear, the graph shows the relative proportion of each age group for the B117 strain versus the *same age group* of the other strain, adjusted for geography & week. Thus its not just “school open” effect. It’s versus the common strain’s same age group, adjusted for time.
