And Another Hope Bites The Dust: Coronavirus immunity can start to fade away within weeks ….

[YippeeKi YOW !!]

It seems like the good news just wont stop rolling in .... here's a little more of the uncertainty/contradictions whirling around the ever widening vortex of COVID and COVID research....

Coronavirus immunity can start to fade away within weeks, according to a new study which puts a 'nail in the coffin' in the idea of herd immunity

We'll find out pretty soon how long the antibodies last, at least with this vaccine-

Moderna COVID-19 vaccine enters final stage trial this month

Washington (AFP) - US biotech firm Moderna said Tuesday it would enter the final stage of human trials for its COVID-19 vaccine on July 27, to test how well it protects people in the real world.

I found the same thing with my EBV antibody test (immunity). I think it may be due to high nagalase inhibiting the immune system. In 2007 I had a positive test then after getting HSV6 all my subsequent EBV tests were negative. This was after I had confirmed mononucleosis. I think ME patients could be in trouble here Yippeeki. They would definitely get re-infected if they don't have a high enough antibody load and have to deal with repeating covid infections. Even if one is normal they have to get two covid infections to build up enough antibody for immunity, just like vaccine booster shots.

Of all the vaccine possibilities I'm least enthusiastic about the Moderna one. I have a hard time trusting this venture capital backed new-fangled method one. I hope one of the others makes good progress, though being VC silicon-valley style company Moderna will likely get all the press and thus be allowed to make the big splash.

A vaccine won't help ME patients if they can't produce the antibodies.

I agree ..... there's something aout the speed with which it was put together that smacks of, as the old Greeks used to say, " .... a sop to Cerberus ...".

I'm not holding my breath .....

I actually have no idea what the old Greeks used to say, but since none of them are around anymore to correct me ......

The drop in antibody levels is only part of the story. What might be more important is how good B memory cells are at recognising covid. Those memory cells might last years. So cant say I am worried about antibody levels dropping.

This means that testing, contact tracing and quarantine will be the new norm. Joe Biden and China were right.

To contain local outbreaks it will be.

@andyguitar
They mentioned cell memory potential in the article, so it's clearly a positive.

At this point, I'm almost as afraid of any potential vaccine, whipped up in the frantic whirlpool of Fear Of Missing Out on this lucrative and fear-driven enterprize, as I am of COVID ....

This virus, and the human body it invades, are both complex, difficult to decode, systems. A speedily produced vaccine is almost a shoo-in for The Law of Unintended Consequences....

And then there's the fact that the vaccine's protection, at least as it seems now, will have to be repeated annually, possible more often for the greatly-at-risk.

It just makes me ..... nervous.

DAMN ..... I wrote this at least 3 hors ago and found it still in Reply box .... just DAMN !!!!

But on the other hand........ Covid might not mutate in the way that flu virus does so the vaccine wont need to be changed, AND B cell memory might last a lifetime. That is what I think will happen.

Covid might not mutate in the way that flu virus does so the vaccine wont need to be changed, AND B cell memory might last a lifetime.

The need for frequent vaccinations has nothing to do with viral mutating or B Cell memory, which has little effect on direct immunity, but with the fact that the antibody protection noted to date tends to apparently fade pretty quickly.

Hence the need to re-esdtablish antibodies at a fairly frequent rate ...
