The COVID-19 pandemic, caused by SARS-CoV-2, continues to rage in many countries, straining health systems and economies. Vaccines protect against severe disease and death and are considered central to ending the pandemic. COVID-19 vaccines (and SARS-CoV-2 infection) elicit antibodies that are directed against the viral spike (S) protein and neutralize the virus. However, the emergence of SARS-CoV-2 variants with S protein mutations that confer resistance to neutralization might compromise vaccine efficacy…
In summary, A.30 exhibits a cell line preference not observed for other viral variants and efficiently evades neutralization by antibodies elicited by ChAdOx1 nCoV-19 or BNT162b2 vaccination.
Another Medical Web Site Warns of the Possibility of the Mu Variant of the Virus Evading Neutralization by Antibodies Elicited by Vaccination
Preliminary data indicate that the Mu variant may confer immune escape similar to the Beta variant. Immune escape is the ability of the virus to evade the body’s immune protection or the protection that vaccines provide.
The moral message to deduce from this, is that medical solutions for Covid are not enough. At the same time that we look for medical solutions, we have to look for the spiritual flaws that allowed the virus to become such a menace and correct those flaws. If we don’t correct the flaws that started the problems G-d can make them surface again in a way that neutralizes our current solutions.
We should not sin like Asa as it is stated in II Chronicles 16:12 (as translated by Sefaria.org except for one word in the sentence): In the thirty-ninth year of his reign, Asa suffered from an acute foot ailment; but ill as he was, he still did not turn to Hashem but to physicians.
