Meanwhile, in Brazil
-
Gov. Andrew Cuomo said on Saturday that a more contagious Covid-19 variant, originally identified in Brazilian travelers, has now reached New York.
The strain was detected by scientists at Mount Sinai hospital in New York City and verified by the Department of Health’s Wadsworth Center Laboratories. The center collects about 90 random samples each day for genomic sequencing and has sequenced more than 8,200 samples statewide.
The patient with the Brazil variant is a Brooklyn resident in their 90s with no travel history, according to a press release.
“The detection of the Brazilian variant here in New York further underscores the importance of taking all the appropriate steps to continue to protect your health,” Cuomo said. The governor urged New Yorkers to continue wearing masks, avoid crowds and get a vaccine when eligible.
The Brazil strain, called P.1, was first identified in four travelers from Brazil who were tested during a screening in Tokyo, Japan, according to the Centers for Disease Control and Prevention.
The P.1 variant was discovered in the U.S. at the end of January. The CDC has since reported 48 cases nationwide. The strain has a set of additional mutations that could impact its ability to be recognized by antibodies.
There’s evidence the variant is more contagious and has the potential to reduce vaccine effectiveness. Researchers at the University of Oxford recently released non-peer reviewed data suggesting it could be less resistant to vaccines. However, additional research is needed.
Have a nice day.

The hope is enough of the truly vulnerable in the US have been vaccinated such that any rise in cases won’t lead to a rise in hospitalizations and deaths.

The worry is that the large chunk of the world that isn’t close to vaccinated will eventually be the source of a mutation for which the current t vaccines aren’t at all effective. Then we’re back to scratch.
Only non-witches get due process.

Is that logical? Wouldn't a country with high levels of vaccination would be more likely to "breed" a new vaccination-resistent variant, since there the mutation has a competitive advantage?

I dont think it would be quite that bad. I was read something that said that the number of mutations that could form that could still attach to the spike of the COVID virus is not unlimited.

Well, the population with few vaccines wouldn’t select for a vaccine resistant strain, it would select for high transmissibility. The population with lots of vaccines would select for vaccine resistance. But the former would have many times more successful mutations.

Agreed, but you said the worry is that mutations would develop in the low-vaccine countries for which the vaccine is not effective. I agree with your last sentence about the number of mutations, but it is not obvious that this is sufficient to "beat" the selection effect of the high-vaccine countries.

I know some have said that we're going to have to deal with Covid for years, possibly decades.
Anyway, happy Monday.

Yeah, it's like "you will get the REAL DEAL someday, a variant."
Swell, huh.

I think the logic goes like this: more transmission leads to more mutations lead to higher probability to produce a vaccine-resistant mutation. Big number without vaccine-resistant selection beats small number with vaccine-resistant selection.

I have read that as well. There are actually relatively few ways the spike can mutate.

In addition, I read that while some future mutations may be more resistant to the vaccines, they won't be completely impervious... The spike protein is the spike protein. It's endemic to this virus and its what each of the vaccines are targeting.

I've read a lot of things in the last year that have been shown to be complete bollocks.
I suspect this will continue.

Hospitalization rates per day compared to % vaccinated per day will give us a decent enough picture, I think.

Update:
https://www.nytimes.com/2021/03/27/world/americas/virus-brazil-bolsonaro.html
More than a year into the pandemic, deaths in Brazil are at their peak and highly contagious variants of the coronavirus are sweeping the nation, enabled by political dysfunction, widespread complacency and conspiracy theories. The country, whose leader, President Jair Bolsonaro, has played down the threat of the virus, is now reporting more new cases and deaths per day than any other country in the world.
“We have never seen a failure of the health system of this magnitude,” said Ana de Lemos, the executive director of Doctors Without Borders in Brazil. “And we don’t see a light at the end of the tunnel.”
On Wednesday, the country surpassed 300,000 Covid-19 deaths, with roughly 125 Brazilians succumbing to the disease every hour. Health officials in public and private hospitals were scrambling to expand critical care units, stock up on dwindling supplies of oxygen and procure scarce intubation sedatives that are being sold at an exponential markup.Intensive care units in Brasília, the capital, and 16 of Brazil’s 26 states report dire shortages of available beds, with capacity below 10 percent, and many are experiencing rising contagion (when 90 percent of such beds are full the situation is considered dire.)
In Rio Grande do Sul, the state that includes Porto Alegre, the waiting list for intensive care unit beds doubled over the past two weeks, to 240 critically ill patients.
