Since humans became humans the best antiviral has been the human immune system. That system has been almost completely ignored during the Covid outbreak in favor of the “wonders” of vaccine-conferred immunity. From Jeffrey A. Tucker at brownstone.org:
Astrange feature of rhetoric during the SARS-CoV-2 pandemic that came to public notice in early 2020 was the odd silence about the immune system. Whereas in the past, vaccines and natural exposure were regarded as partners in disease mitigation, this time they were set up in competition, with all respectable voices pushing vaccines and shouting down anyone who dared break the silence about natural forces.
That propaganda push started 18 months ago but it has now completely unraveled. The largest study yet comparing Covid vaccines to natural infection has produced results that would have surprised no one 50 years ago. “Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections” demonstrates that natural immunity is more powerful and broader in terms of preventing infection – a truism of cell biology known and refined over the ages. This is consistent with many other studies over the past year, as explained by Jay Battacharya, Sunetra Gupta, and Martin Kulldorff.
Experience with Covid-19 is a textbook case of how the immune system scales naturally to take on the newest pathogens that have always and will always vex the world. The vaccine (especially one using a new innovation rather than a traditional inoculation) for this type of virus – respiratory, widespread, and mild for most – will necessarily be more hit-and-miss, simply because of the pace of mutation and the emergence of variants.
The Isreali study is notable only because of the scope of the study and the precision of the results. Reuters summarizes the study in English:
The results are good news for patients who already successfully battled Covid-19, but show the challenge of relying exclusively on immunizations to move past the pandemic. People given both doses of the Pfizer-BioNTech vaccine were almost six-fold more likely to contract a delta infection and seven-fold more likely to have symptomatic disease than those who recovered.
