Vaccine ‘passports’ must give credit for natural immunity

By Joel S. Hirschhorn

Anyone truly committed to following science should enthusiastically demand that any mandates for COVID vaccination give credit for natural immunity resulting from a prior infection. Indisputably, all medical research shows that natural immunity is even better than vaccine immunity.

Before reading some of the relevant medical data, consider that some countries are acting in a far better way than U.S. federal agencies like FDA, CDC and NIH.

Israel has a Green Pass program that provides access to public venues like museums, restaurants and gyms. It officially recognizes immunity from either vaccination or recovery from COVID infection – meaning natural immunity.

Similar to this wise government policy is that France, Germany and Italy advise just one dose of a COVID vaccine for those with prior infection. This is a clear recognition by these governments that natural immunity really has scientific merit.

In May, MedPage Today published an editorial titled “Quit Ignoring Natural COVID Immunity,” by two physicians. Here are some highlights from it.

“Those who have recovered have an astonishingly low frequency of repeat infection, disease, or death.”

NIH reported this: “The immune response of more than 95% of people who recovered from COVID-19 had durable memories of the virus up to eight months after infection.” This is quite impressive considering that most data on breakthrough infections in vaccinated people indicate a loss of effective immunity after about six months.

“The range of reduction of re-infection from COVID-19 was between 82% to 95% among six studies that encompassed nearly 1 million people conducted in the U.S., the U.K.DenmarkAustriaQatar and among U.S. Marines. The study in Austria also found that the frequency of reinfection from COVID-19 caused hospitalization in only five out of 14,840 (0.03%) people and death in one out of 14,840 (0.01%). In addition, newer U.S. data, released after the January NIH announcement, found protective antibodies lasting up to 10 months following infection.”

“There are multiple highly encouraging research reports showing that blood cells in our body, so called ‘B cells and T cells,’ contribute to the cellular immunity after COVID-19. If SARS-CoV-2 immunity is similar to other severe coronavirus infections like SARS-CoV-1 immunity, that protection could last at least 17 years. However, tests to measure cellular immunity are complex and expensive, making them hard to get and preventing their use in routine medical practice or in public health surveys of the population.”

“Given that 90% to 99% of people who recover from COVID-19 develop detectable neutralizing antibodies, doctors can use the correct test to inform people of their risk. We can counsel patients that those who have recovered from COVID-19 have a strong protective immunity, protecting them from repeat infection, disease, hospitalization, and death. In fact, that protection is similar to or better than vaccine-induced immunity. Putting that together, people who have recovered from prior infection or those with detectable antibodies should be considered protected, similarly to someone who is vaccinated.”

  1. Give em an inch and they’ll take a mile. No, your idea excludes many healthy, vigorous individuals who may not yet have gotten CV19, but would not be in danger of it (like children, duh!). Passports are the proverbial line in the sand which must be fought against with every fiber of our being, no matter what we think of vaccines.
