The virus is now embedded in our world. But there are steps we can take to keep it at bay while we continue to live our lives.'

[What do I wish I had known in early 2020? Other than to buy shares in toilet paper, Zoom and vaccine companies, I wish I had known that a safe and effective vaccine against severe disease and death from Covid-19 would arrive within a year and that reinfection would nevertheless become a major issue in managing the disease. These two facts would have shifted the UK governments response, and allowed for a more unified scientific front in advising them.
At the very beginning of the pandemic, several governments including in Sweden, Netherlands and the UK believed the best path through this crisis was to allow a controlled spread of infections through the population, especially the young and healthy, in order to reach some static state against the virus. The idea was that the herd who got infected would protect a more vulnerable minority.
This concept came from our approach to other vaccines, in which we inoculate the majority of children against, for example, measles, mumps and rubella (MMR) in order to protect those who cannot be vaccinated due to health conditions. If Sars-CoV-2 only infected people once, or vaccinated people couldnt catch Covid (ie if infection or vaccination resulted in lifelong immunity) then herd immunity would be possible. By now, we would have eliminated Covid completely in the richer world where seroprevalence estimates of antibody levels are more than 90%, and in Britain as high as 98%.
However, this is far from the position were in. The rising number of documented reinfections, sometimes occurring relatively quickly after the initial infection, as well as the high number of infections with the Omicron variant among the fully vaccinated, means that herd immunity is likely impossible even if seroprevalence hits 100%. Relying on herd immunity to manage Covid-19 rather than on the strategies of east Asian countries to suppress it until a vaccine was available was a gamble that Britain took early in March and unfortunately lost. Especially given the presence of variants, Sars-CoV-2 will just keep circulating and reinfecting people.]
There's much more text and photos at the link. This is a very long Opinion piece and
while it's focused on The U.K. Experience it is very informative and useful.
My takeaway is: Keep mask and vax mandates in place. Of course, that's my plan.
And don't trust governments, The WHO, The NHS or The CDC. Of course, I've
followed that from the beginning too. Surviving is a lot of work but it's worth it.

Like smallpox, TB, polio, cholera and so many others once were before effective public heath measures were taken to make them rare.
Herd immunity was and always is a myth outside of a small isolated homogenous population or a laboratory setting.

(37,847 posts)The only reason those viruses are less severe is because they have been around for millions of years and a pitched battle has been fought between higher animals and those viruses creating a highly complex immune system via evolution. This protects from those specific and well known pathogens. At one time, the viruses classified as the common cold were extremely lethal. Thus prompting the evolution of a creature that could withstand the onslaught.
Going back to day one of COVID. This is a NOVEL virus. Meaning no animal and particularly human immune systems had ever encountered them before. Coupled with its relatively small genetic structure making it highly susceptible to mutation (much more than even the flu) makes every infection of every cell a variant brewery. Again, via evolution, some variants are robust and most arent. The cycle repeats.
Vaccination is an excellent back-up. However, if the COVID virus remains in general circulation and waved off as endemic it is not a matter of if, instead being when it hits a combination of both transmissibility and lethality to be a species ender. Humans dont have the time to evolve out of it.
For reference see the post European contact era when three waves of various diseases wiped out 90% of the indigenous population and took a big bite out of the newly arrived population.

The cycle with COVID is following many other cycles with similar ACTING viruses.

(37,847 posts)I agree that wouldnt have happened in the 15th century and it took 40 years to depopulate the Americans. Now, a year or less? Certainly not enough time to field an effective response. Those who decide these things have chosen to roll the bones and let her rip. Who am I to get in their way? AIDS was initially spread via air travel, if you would like a more recent example.
The variants of the COVID virus weve seen so far are acting like known viruses.
However, with each new infection that could change.
Like with global warming, FAFO.

The protection is dramatic. You are 4 to 5 times less likely to get Covid if you're boosted. You are 97 time less likely to die of Covid if you're boosted.
