“This is not a major threat that the people of the United States should be worried about.” Dr. Anthony Fauci, January 21, 2020.
“I think you are going to see a dampening down of U.S. cases.” Dr. Anthony Fauci, February 3, 2020.
“In order to get a vaccine that’s practically deployable for people to use, it’s going to be at least a year to a year and a half at best.” Dr. Anthony Fauci, February 26, 2020
“There’s no reason to be walking around with a mask.” Dr. Anthony Fauci, March 8, 2020
Dr. Fauci was informed as early as February 2020 that Covid-19 exhibited unusual viral characteristics that suggested it could have potentially been engineered in a lab, according to emails recently obtained by the Washington Post and BuzzFeed.
Some Republican lawmakers have used the emails to accuse Dr. Fauci of having played down the lab-leak theory.
“Most of the people thought what all of us were thinking at the time—that it was very likely a natural evolution. But we never ruled out the possibility. We were very open about it. It wasn’t like we were trying to hide anything,” he said.
Dr. Fauci said misinformation that has been circulated about the virus, particularly around it being a hoax, has ultimately cost lives, because some people didn’t wear masks or social-distance as a result.
Many of the fundamental features of life don’t necessarily have to be the way they are. Chance plays a major role in evolution, and there are always alternate paths that were never explored, simply because whatever evolved previously happened to be good enough. One instance of this idea is the genetic code, which converts the information carried by our DNA into the specific sequence of amino acids that form proteins. There are scores of potential amino acids, many of which can form spontaneously, but most life uses a genetic code that relies on just 20 of them.
Over the past couple of decades, scientists have shown that it doesn’t have to be that way. If you supply bacteria with the right enzyme and an alternative amino acid, they can use it. But bacteria won’t use the enzyme and amino acid very efficiently, as all the existing genetic code slots are already in use.
In a new work, researchers have managed to edit bacteria’s genetic code to free up a few new slots. They then filled those slots with unnatural amino acids, allowing the bacteria to produce proteins that would never be found in nature. One side effect of the reprogramming? No viruses could replicate in the modified bacteria.
The dramatic ramp up comes at an awkward time, however. Early adopters of China’s vaccines have seen dramatic surges in COVID-19 cases—despite high vaccination rates—and are now backing away from the country’s offerings.
In Bahrain, for instance, officials are now offering high-risk people who have already received two doses of China’s Sinopharm vaccine a third vaccine dose—but one made by Pfizer-BioNTech. The apparent vote of no confidence by officials is striking: Bahrain was one of the first countries to back and rollout Sinopharm’s vaccine, and it has had a highly successful vaccination campaign. Nearly 58 percent of the Persian Gulf country has received at least one dose of a vaccine, and most of the vaccines given in Bahrain are from Sinopharm. But the country is now seeing its worst wave of COVID-19 yet and the government has recently issued a two-week lockdown to try to get transmission under control.
The Seychelles went through a similar struggle. The archipelago saw a dramatic spike in cases in mid-May, despite having around 70 percent of its population vaccinated with at least one dose. Like Bahrain, the Seychelles had largely relied on the Sinopharm vaccine.
Dubai, which has also relied on Sinopharm’s vaccine, is now quietly offering residents who have been fully vaccinated with the Sinopharm vaccine the opportunity to get re-vaccinated with the Pfizer-BioNTech vaccine, according to The Wall Street Journal.
