Default Mutations Not Enhancing COVID Spread

At least not so far.

Makes sense, because the original version spreads pretty well, it doesn't actually need to mutate to thrive.

Vaccines might change that, since it will experience evolutionary pressure to work around vaccines (which it may or may not be able to do, to a greater or lesser degree).

resurrecting a thread to demo how quick things are changing:


Fears that the vaccines would be powerless against new variants intensified at a scientific conference held online on Saturday, when South African scientists reported that in laboratory tests, serum samples from 21 of a group of 44 Covid-19 survivors did not destroy the variant circulating in that country.

The samples that were successful against the variant were taken from patients who had been hospitalized. These patients had higher blood levels of so-called neutralizing antibodies — the subset of antibodies needed to disarm the virus and prevent infection — than those who were only mildly ill.

The results “strongly, strongly suggest that several mutations that we see in the South Africa variant are going to have a significant effect on the sensitivity of that virus to neutralization,” said Penny Moore, a virologist at the National Institute for Communicable Diseases in South Africa who led the study

it’s only been a year or so and so much of what we ‘know’ about this organism is still sort of tentative. And what was entirely correct not too long ago is only MOSTLY correct today.

Vaccinations do appear to give more infection against the mutant strains than mild asymptomatic infections though.

So far at least.

Phheewww. Good to hear. I was scared this pandemic was going to get worse. I heard we are at an all time high for covid deaths. That number from April just keeps going up.....slowly.

I will make a bold prediction that next month we will be at an all time high for COVID-19 deaths also. and the month after that, there will be even more!

Eventually all pandemics end. If only because you run out of 80 year olds with comorbidities...

This one is not going to end for another few years.

And the vaccines and those who have already had it reduces the transmission rate. As an example if the average person contacts and transmits to 2 people, they give it to 4, then to 8 by the third generation.

With 70% vaccine and already have it (caution, math ahead), 1 gives it to 2 x (1-.70) = 0.6 persons, it starts declining pretty rapidly.

The new UK variant of COVID-19 - which is up to 70% more transmissible - could be more deadly than the original virus, the prime minister has warned.

From CNBC....

Dr. Fauci says new data shows Covid vaccines appear to be less effective against some new strains

KEY POINTS
  • Early data shows that the Covid-19 vaccines on the market may not be as effective in guarding against more contagious strains of the coronavirus, Dr. Anthony Fauci said Thursday.
  • Even if the drugs are less effective, they will still likely provide enough protection to make the vaccines worth getting, he said

cases are coming down, and restricting travel from South Africa while cases of B.1.351 are coming down too - I still feel optimistic about 2H21. Although not if the MSM wants to keep the fear mongering though.
