Natural COVID-19 immunity is powerful -- but kind of irrelevant

Good piece for the vaccine hesitant and those who wonder why they should get vaccinated even if they've had COVID, and for Republicans who keep complaining about why natural immunity doesn't get credit.


"Over 43 million Americans have reported cases of COVID-19. Many of them likely have some amount of natural immunity, and this kind of immunity can be quite protective, even without vaccination. Why does it seem that scientists are ignoring natural immunity in the national discussion of vaccine mandates and vaccine passports?

Natural immunity can, indeed, be powerful. Even before vaccines were available, individuals who recovered from COVID-19 had detectable T-cell responses, and reinfections were rare, at least prior to the emergence of the aggressive Delta variant.

However, the scientific community strongly recommends vaccination even in people who had COVID-19 infection. There are very good reasons for this. Every component of the immune response to the SARS-CoV-2 virus improves after vaccination, including antibodies and T-cells. In those with prior COVID-19 infection, vaccination can elicit important cross-variant neutralizing antibodies. And clinical protection improves after vaccination in people who had prior infection: In a recent study, people with prior COVID-19 who received even one vaccine dose had half the risk of a breakthrough infection than unvaccinated people with prior COVID-19. So, vaccination even helps those with prior COVID-19 (and everyone they interact with). "


"Not everyone who has a case of COVID-19 will have natural immunity. In a recent Centers for Disease Control and Prevention (CDC) study of those with prior COVID-19 infection, 36 percent did not form any antibodies against the virus. This is in stark contrast to antibody formation in 100 percent of (non-immunocompromised) people who receive even one dose of an mRNA vaccine (Pfizer or Moderna), as impressively reported in the large vaccine trials. So, from a practical perspective, if a business or school is trying to figure out if someone is safe to be around, they can rest quite assured that someone who shows them vaccine proof is safe, but it would be nearly impossible to determine if someone with prior COVID-19 is safe. Beyond the logistical issues of proving that a person had prior COVID-19, how can they prove they're in the 64 percent who have some natural immunity?"

Do we have any answers after all these years why so many 9/11 forewarnings were ignored?

Not just the famous Aug 6th PDB, but there were at least 2 high profile FBI whistleblowers saying that their warnings were being ignored, including Colleen Rowley, who was in charge of the case of the 20th hijacker who was arrested before the attacks, Zacarias Moussaoui.



Also keep in mind that the great Robert Mueller was in charge of the FBI at that time.

Never forget how Bush ignored, dismissed, downplayed multiple warnings of an Al Qaeda attack

prior to 9/11. Mehdi Hasan reminds us.
