Good news and bad news in the COVID articles for today. Cases and deaths continue to lessen. Vaccinations continue to increase, but new variants keep appearing. The one in NY has a mutation in the spike protein that causes the body to have a lessened immune response against it. It is definitely one to watch.


Good News - COVID Cases and Deaths Decreasing

Bad News - New Variant in NY is One to Watch



ETA: Here is an AP article discussing low flu cases. I know we all have discussed this previously.
Flu has Disappeared

Based on the article I posted last week with the interview of Dr. Mina of Harvard, he talked about mutations and how poorly the US doing in testing for mutations/variants across the population. I suspect there are a lot of variants present that we have no idea are present. Some of these variants will be successful and increase in prevalence and others will fail to spread and die out. Who knows what will happen with the new one from NY.

Last year, I do recall reading reports that suggest virus' typically become less virulent over time, so it would be interesting if the coronavirus that causes Covid-19 is becoming more deadly through mutation. I need to do some more research on this area to better understand the mechanisms that would cause them to become more virulent. I am sure it is possible, but I do not understand how this happens.

It is actually in a virus's best interest to become less deadly and to decrease it adverse effects on the human hosts. For example, I have seen some early studies on the UK mutation that suggest that while it was more contagious, it was not more likely to cause you to be hospitalized. Even though the prevalence of it increased in the UK, hospitalization increases could not be correlated to the increase in prevalence. I am sure this is still being studied, along with the South African variety.

The use of narrow spectrum vaccines (the current Pfizer and Moderna vaccines are narrow spectrum) is a limitation when the virus is effectively mutating. All our current vaccines are focused on the spike protein and as such, variations in the spike protein could decrease the vaccines effectiveness. As you pointed out, the current vaccines are still effective against some of these known mutations, but eventually there will be a mutation that can evade the bodies built-up antibodies and T-Cells. Let's all hope this does not happen.

Here's what Dr. Mina said on the vaccines and mutations in the referenced article:

"Another issue: All of the major vaccines that we are building all present the exact same spike protein. They're all clones of each other no difference for the most part. Nobody ever took a step back to say, what if this virus mutates? We are vaccinating with a narrow-spectrum vaccine against one piece of the virus. If that piece mutates, it would be able to escape all of our vaccines. And all it needs to do is mutate once, somewhere in the world. And then all of our major vaccines are moot. Why was that not considered?"

"And we're doing so little genetic surveillance of the disease here in the States, we don't even really know what strains are here. We're flying blind."

"We'd much rather just wait and then blame South America and blame the U.K. Meanwhile, we're probably getting the identical variants here not just because they're being brought in by travelers, but because they are probably being built right here in the U.S. through mutation and viral evolution. But now we can blame it on South America or South Africa and the U.K. instead of blaming it on ourselves."

As to a virus potentially becoming less virulent, here is what Dr. Paul Sax said in the article I linked earlier this week:

"Maybe the virus is doing us a favor and becoming less virulent over time. Perhaps some of these variants if not B.1.1.7 in order to gain the ability to transmit, also cause less severe disease."

"Take the virus's perspective yes, think like a virus and how this would be evolutionarily beneficial. More mild cases, more chance to spread its genetic material to other susceptible hosts. That's all viruses care about, right?"

Why are Covid-19 Case Numbers Dropping?

Great news!! As expected, the J&J vaccine has been approved by the FDA's Vaccines and Related Biological Products Advisory Committee. It is expected that vaccine doses should begin to arrive in NC starting next Wednesday.

Here's a good interview for you to read, rww26

Excellent article. Thanks for posting Mormad. I thought a couple of things she said really registered with me with regards to Covid-19. These were around the importance of being outside and good ventilation, the over-emphasis on variants by the press, and the failure to consider "harm reduction" in applying broader harms to the policies enacted.

Very similar to the article Mormad posted, the following article in The Atlantic takes a similar tone, even discussing the idea of "harm reduction." As I have mentioned in a couple of recent posts, the messaging by Dr. Fauci and others really needs to improve and this article makes a very similar case. I encourage you to read this one, along with the article Mormad posted.
