The NYT’s map of hotspots illustrates that areas that saw lots of Covid cases in the spring or summer (NYC, NJ, Boston, much of the South) are seeing relatively fewer new cases now. This presumably reflects the fact that these areas have fewer people susceptible to the virus.
“All six previously known coronaviruses spark production of both antibodies and memory T cells. In addition, studies of immunity to SARS-CoV-1 have shown that T cells stick around for many years longer than acquired antibodies…. It’s still not clear if this [SARS-2] acquired immunity stems from previous infection with coronaviruses that cause the common cold or perhaps from exposure to other as-yet unknown coronaviruses.”
I’m suggesting that although there are probably few areas of the US with sufficient levels of immunity to stop all transmission, there is sufficient “herd” immunity now to keep cases from exploding in areas that previously exploded. Time will tell if I am correct.
Strangely, the media are pretty quiet about the case numbers today, with many more cases and hospitalizations than there were in the summer, when the media discussion was deafening.
Could it be that all these cases are at odds with the plan to vaccinate everyone with novel vaccines? If we achieve high levels of immunity due to disease exposure, the experimental vaccines may look a lot less inviting.
The WHO suggested that 20x as many cases have probably occurred as those we know about, worldwide. The US has had over 10 million known cases, and cases are rising rapidly. If the US had had ten times as many cases as were diagnosed, there would be 100 million Americans with partial or complete immunity from exposure. If an additional 20% of us had pre-existing immunity, then half of the country would already be immune.
If my odds are 50% that I am already immune to Covid-19, why would I accept a vaccine that is known to make me feel like I had a bad hangover, and might cause other side effects longterm? I am not impressed that the vaccines are only being asked to demonstrate efficacy against mild disease in the clinical trials, and it is still uncertain whether a vaccinated, exposed person is prevented from spreading the infection.
We have been told that even after being vaccinated, we will still have to wear masks. I think I’d prefer to take my chances with the disease, knowing that zinc, vitamin D, vitamin C and early hydroxychloroquine/azithromycin almost guarantee me a mild case.
Not to mention that there continues to be concern that novel vaccines might prime us in such a way that makes a case of Covid worse, causing even more autoimmunity. This happen with a measles vaccine and an RSV vaccine back in the 1960s. Neither vaccine gave recipients immunity; instead each caused severe disease when recipients were exposed to the virus the vaccines were intended to protect against. This happened more recently when experimental coronavirus vaccines were used in animal experiments.
When millions of people are vaccinated close together, as soon as a vaccine is given regulatory approval, they don’t benefit from seeing how earlier recipients fared. Even though there have been many thousands of experimental subjects in vaccine trials, there have been only a few weeks or months in which to observe them for adverse effects. And because the vaccine manufacturers are not liable for damages, unless they conceal evidence of side effects, the manufacturers are incentivized to speed the vaccines’ evaluation, and learn as little as possible about their side effects.
The media were surprisingly willing to discuss possible vaccine side effects, as long as the Warp Speed vaccines were Trump’s project. I expect to see a 180 degree shift in their approach, as soon as the election is definitively called. Watch for it.
