Yale Study: Natural Immunity Protects Against COVID Three Times Longer Than Vaccine

To their dismay, the Yale School of Public Health just concluded that immunity acquired by COVID-19 infection lasts three times longer and is stronger than that provided by vaccination. Naturally, the Yale Daily News downplayed the info under the headline, “COVID-19 reinfection is likely among unvaccinated individuals, Yale study finds.”


The Yale study concluded that the risk of COVID-19 reinfection stands at 5% at three months after recovery and decreases to 50% at 17 months. By contrast, COVID-19 vaccine protection against infection can wane to a mere 20% as early as five months after full vaccination. Now, I may not be a Fauci-approved Scientist, but I’m also not stupid.

The Yale study joins the ever-growing compendium of studies that attest to the superiority of natural immunity over vaccination for protection from COVID infection. It’s worth clicking over to the linked article because you probably had no idea there was already so much Science! proving the point.

Here are a few highlights from the Blaze Media listicle by Daniel Horowitz:

New York University, May 3, 2021

The authors studied the contrast between vaccine immunity and immunity from prior infection as it relates to stimulating the innate T-cell immunity, which is more durable than adaptive immunity through antibodies alone. They concluded, “In COVID-19 patients, immune responses were characterized by a highly augmented interferon response which was largely absent in vaccine recipients.”

Cleveland Clinic, June 19, 2021

In a study of 1,359 previously infected health care workers in the Cleveland Clinic system, not a single one of them was reinfected 10 months into the pandemic, despite some of these individuals being around COVID-positive patients more than the regular population.

Aside from more robust T cell and memory B cell immunity, which is more important than antibody levels, Israeli researchers found that antibodies wane slower among those with prior infection. “In vaccinated subjects, antibody titers decreased by up to 40% each subsequent month while in convalescents they decreased by less than 5% per month.”

Irish researchers, published in Wiley Review, May 18, 2021

Researchers conducted a review of 11 cohort studies with over 600,000 total recovered COVID patients who were followed up with over 10 months. The key finding? Unlike the vaccine, after about four to six months, they found “no study reporting an increase in the risk of reinfection over time.”

I could link these all day, but I’m sure we both have other things to do. The point is that the Science! is more consensus-y every day: those who have already recovered from a COVID infection—even a mild or asymptomatic one—have naturally superior protection from future infection to those who are merely vaccinated, and are also safer to be around than people who have been vaccinated but never had an infection.

I’m not saying you shouldn’t get vaccinated if you already had COVID, especially if you are tolerant of the vaccine’s side effects. According to the experts, you would be even better protected than people who are either only naturally immune or only vaccinated. But if you have recovered from an infection, you’re manifestly as safe as if you were only vaccinated.


Clearly, it’s time for public safety policy to recognize natural immunity as equal to vaccination.

Of course, the government-pharma complex isn’t going to give up its advantage without a fight. Big Pharma has a lock on all that sweet vaccine cash, and our leaders simply love their hot new emergency powers. But cracks are finally appearing in the “crisis” power apparatus. The more Americans insist we Follow the Science™ and grant equal rights to the naturally immune, the faster this much-needed transformation can occur.
