The “HOLY MOTHER OF GOD” tweet was exactly 1 year ago today. For those who have been with me this past year, I hope and pray your families are safe. Let’s work together to end this pandemic. #COVID19 https://t.co/I5G7PL6boG

12) “No one B.1 variant carries all these mutations, but each must confer some selective advantage to the A lineage variant.” Translation: Tanzania variant (from A lineage) somehow has converged somehow with the bad mutations from B. Convergent evolution usually bad.

11) “Of the 13 mutations that distinguish the spike protein of the Tanzanian variant from the original Wuhan strain, eight are found in the B.1 family of variants. This is a remarkable illustration of convergent evolution.”

10) “Nonetheless, the new variant is of interest and of possible concern as it carries a number of mutations in the spike protein characteristic of other bonafide variants of concern from the B.1 lineage.

9) “The Tanzanian variant (which is how I will denote it as it lacks official designation) teaches us that variants of interest and concern may lack all three defining mutations of the B.1 strain.

8) “It evolved from an entirely different source, the A lineage, a finding that substantially expands our understanding of the repertoire of mutants we must be prepared to contend with in the months and years ahead.”

7) Back to Tanzania variant—“Up until the discovery of the new variant, all other variants of interest or concern derive from a common ancestral virus, the B.1 strain that first made its appearance in early 2020. This is not so for the newly described variant...”

5) “The appearance of a new variant of interest & possibly of concern detected in travelers from that country highlights the need for transparency, both for control of Covid-19 within the country and for the dangers viruses emanating from Tanzania may pose for rest of the world.”

4) “That is partly due to the new total blackout of information during the pandemic from that country. Official data would have that no infections have occurred in Tanzania since May 2020, which is clearly not the case.

3) “It also represents why we need more comprehensive variant surveillance around the world. Were this not detected in the Angolan airport, it may have caused havoc in the country and elsewhere.  We do not yet know exactly how dangerous the Tanzanian variant may be.

2) “This is another variant we have to be especially vigilant towards. It may be as infectious and immune evasive as the widespread B.1.1.7 and B.1.351 variants, in addition to potential reinfection capabilities, as they carry similar mutations”

⚠️TANZANIA VARIANT—One of the most preeminent Harvard virology professors is trying to warn—Tanzanian variant branched off Wuhan 1.0 strain but acquired all the bad mutations of #B117 & #B1351 independently—convergent evolution.

3) India is now home to the world’s fastest-growing Covid-19 crisis, reporting 294,000 new infections on Wednesday and more than 2,000 deaths. As supplies of hospital beds, oxygen and vaccines run low, criticism of the government is building.

2) “All week, hospitals across India have been warning about an acute oxygen shortage. Many hospital officials said they were just a few hours away from running out. “Nobody imagined this would happen,” said Subhash Salunke, a medical adviser to the Maharashtra government.

OXYGEN CRISIS again. More than 20 #COVID19 patients suddenly died after a leak in an Indian hospital oxygen tank stopped the flow of oxygen to dozens of critically ill people. Televised images showed family members wailing & nurses frantically doing CPR.😢 https://t.co/wMYDJskcKz

Important: The rate of blood clots with low platelets reported with Pfizer and Moderna are LOWER than expected for general population. These vaccines are safe and don't carry excess risk. https://t.co/Np5wKgy7pP

Finally got some data from EMA to put numbers of thromboses with thrombocytopenia after #covid19 vaccines in perspective (this is only for European Economic Area): AstraZeneca - 142 in 16 million Pfizer/Biontech - 11 in 59 million Moderna - 2 in 5.2 million

3) “About 80 people at a clinic in Mexico received a fake vaccine going for about $1,000 a dose, though they don’t appear to have been physically harmed. The vials, found in beach-style beer coolers, had different lot numbers than those sent to the state, & wrong expiration date
