South Africa strain is beginning to get around the vaccine

Walt said:
If it is evolving around vaccines and natural immunity fast enough to become seasonal, then herd immunity will never be achieved. Or more accurately, herd immunity to one strain will be achieved, but it will move on to another strain every time.

Even there, it has been proven that immunity to Covid-19 fades relatively quickly, so we could even get the same strain multiple times.



Influenza would be a good example. We have never achieved immunity to influenza, but rather to each successive strain. Of course Covid-19 would be worse as immunity to previous strains faded, whereas influenza immunity is for life.

No it isn’t lol.

If that were true there would be no need for flu vaccines. Likely what goes on is novel viruses cease to be ‘novel’ with respect to the human immune system as time goes on.

Even though the virus may tweak itself through evolution over time, it retains enough of the C-19 protein structures that these are then recognized by the immune system—it’s no longer a novel virus. Fewer people get deathly sick with it as a consequence and the result is a less virulent virus.

See Alter, it doesn’t always have to be death and misery.

If we could achieve immunity to all influenza, we would only need one influenza vaccine. The best we can hope for is immunity to each new strain that comes out, with multiple new strains coming out every year. That is why it is seasonal.

If Covid-19 becomes seasonal, we will be looking at the same.

And...since it will have been around for awhile, our collective immune systems won’t be caught ‘flat-footed’ so to speak.

It’s still early but when we get sufficient data from people who have been infected by both strains don’t be surprised if the second go round produces milder symptoms—because that is the most likely outcome.

Why only South Africa? It also mutated in the UK. And it has already spread out of both countries, and both strains are already in the USA. Not to mention there is very little cross border movement anyway.

The South African strain has not been detected in the US, yet, the British mutant has been and the vaccine works fine with it. Just the facts....

About 2 to 3 percent of people who get Covid-19 get long covid, which can spend months ravishing the body. Even those who get the shorter version often have lifelong damage from it. Almost certainly, this lifelong damage would be cumulative over repeated infections.

You are correct. South African strain has not been detected in the USA. The UK strain is definitely in the USA, and will be hitting us hard in March-ish. The UK strain is far more transmissible, but not better at getting around the vaccine.

There is a California strain that appears to be similar to the South Africa strain. The California strain might be able to get around the vaccine, much like the South African strain might. The key word throughout here is "might". There is nothing definite yet. The California strain is definitely in the USA, having been first detected in California.

The South African strain of Covid-19 has a lower response to the vaccines. Hopefully, it is not enough to make the vaccines ineffective, but because we have no idea how effective they are in preventing transmission, we can not be sure.

The UK strain is not causing a problem with the vaccines, but is twice as transmissible as the original Covid-19.

At some point the two are probably going to intermix. If two different strains of a virus infect the same cell, at the same time, the viruses that come from that will share traits of both strains.

So lots of bad news. This is quickly moving towards being seasonal, which might mean we will be dealing with this for decades.

As with any problem, giving up hope does nothing. But, false hope also does nothing good. We have to keep working hard to defeat this.

nah.

the vaccine is murder. reject it.

The survival rate is close to 99.8%. I think we'll all be fine.

The South African strain ignored if you had it before so you can get it repeatedly. The antibodies do not stop it.
Survival rates differ by age of people who get it. Older people are much worse in survival. There are many who get lingering symptoms that have left them debilitated.
Shrug it off at your own risk and your families.
