The following article was written by Eric Levenson for CNN. It was published last January 8, 2021.
In this article, Levenson explores the various reasons why a COVID-19 vaccine is not a guarantee that a person will no longer be infected when they have been vaccinated. Some of the reasons Levenson explored included the following: (1) Immunity takes time, (2) Vaccines do not provide perfect protection, and (3) Immunity wanes over time. Levenson also repeats statements from Dr. Anthony Fauci and other experts that vaccines may not prevent transmission [see Fauci: Early COVID-19 vaccines will only prevent symptoms, not block infection, Operation Warp Speed chief adviser: We don’t know if people can spread COVID after vaccination, Moderna chief medical officer: No hard evidence showing vaccine can stop spread of virus].
Editor’s Note: Based on the reasons explored by Levenson in this article, we can say with great confidence that herd immunity offers greater protection from COVID-19 compared to vaccine-derived herd immunity.
For one, it is a known fact that humans who have not yet been exposed to SARS-CoV-2 have inherent immunity due to their exposure to other coronaviruses, such as those that causes the common flu [see New study found pre-existing SARS-CoV-2 immunity in general population and Herd immunity may still be the key to fighting COVID-19]. Moreover, immunity built from natural exposure to the virus last for months, if not years [Immune memory offers hope for collective immunity, CNN Report: Immunity to SARS-CoV-2 last for months, Swiss immunologist explains existing immunity to SARS-CoV-2 and the myth of asymptomatic carriers].
Lastly, natural immunity does not wane over time. Instead, it teaches a healthy human body to adopt to new threats [see Our complicated relationship with viruses, Prof. Sunetra Gupta: Let children be exposed to viruses, Understanding the immune system of children may be the key to understanding susceptibility to SARS-COV-2].
Even with the new mRNA technology, vaccines can ever replace the human immune system [not to mention the fact that the new COVID vaccines are causing numerous side effects, see COVID vaccinations causing 50x the adverse effects of flu vaccines, Perfectly healthy doctor dies weeks after getting Pfizer COVID vaccine, Health workers got emergency treatment after Pfizer vaccine shot].
