Thoughts on economics and liberty

Having had covid reduces further hospitalisation risk 8 times compared with vaccines. BUT vaccines FURTHER enhance immunity of those previously infected.

This is a placeholder post – will add when time permits.

The title of the post reflects my current understanding of the facts. The main paper is still under peer-reviewed so some of it might change. I believe that the much feared ADE has NOT happened. Therefore there is an argument to be made that those who have been vaccinated and get a “breakthrough” reinfection, are likely to end up with even stronger immunity at the end of the process, if they survive.

Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections

The natural immune protection that develops after a SARS-CoV-2 infection offers considerably more of a shield against the Delta variant of the pandemic coronavirus than two doses of the Pfizer-BioNTech vaccine, according to a large Israeli study.

people who once had a SARS-CoV-2 infection were much less likely than never-infected, vaccinated people to get Delta, develop symptoms from it, or become hospitalized with serious COVID-19. The study demonstrates the power of the human immune system.

The study, conducted in one of the most highly COVID-19–vaccinated countries in the world, examined medical records of tens of thousands of Israelis, charting their infections, symptoms, and hospitalizations between 1 June and 14 August, when the Delta variant predominated in Israel. It’s the largest real-world observational study so far to compare natural and vaccine-induced immunity to SARS-CoV-2, according to its leaders.

It’s a textbook example of how natural immunity is really better than vaccination,” says Charlotte Thålin, a physician and immunology researcher at Danderyd Hospital and the Karolinska Institute who studies the immune responses to SARS-CoV-2. “To my knowledge, it’s the first time [this] has really been shown in the context of COVID-19.”

The new analysis relies on the database of Maccabi Healthcare Services, which enrolls about 2.5 million Israelis. The study, led by Tal Patalon and Sivan Gazit at KSM, the system’s research and innovation arm, found in two analyses that never-infected people who were vaccinated in January and February were, in June, July, and the first half of August, six to 13 times more likely to get infected than unvaccinated people who were previously infected with the coronavirus. In one analysis, comparing more than 32,000 people in the health system, the risk of developing symptomatic COVID-19 was 27 times higher among the vaccinated, and the risk of hospitalization eight times higher.

people who had SARS-CoV-2 previously and received one dose of the Pfizer-BioNTech messenger RNA (mRNA) vaccine were more highly protected against reinfection than those who once had the virus and were still unvaccinated. [Source:]

In other words, taking a vaccine AFTER having first being infected further strengthens the immune response. The vaccine therefore seems to act as a booster for natural immunity.

High genetic barrier to escape from human polyclonal SARS-CoV-2 neutralizing antibodies

the immune systems of people who develop natural immunity to SARS-CoV-2 and then get vaccinated produce exceptionally broad and potent antibodies against the coronavirus. The preprint, for example, reported that people who were previously infected and then vaccinated with an mRNA vaccine had antibodies in their blood that neutralized the infectivity of another virus, harmless to humans, that was engineered to express a version of the coronavirus spike protein that contains 20 concerning mutations. Sera from vaccinated and naturally infected people could not do so. [Source:]


PEER-REVIEWED: 14 June 2021

Naturally enhanced neutralizing breadth against SARS-CoV-2 one year after infection

people who recover from a SARS-CoV-2 infection continue to develop increasing numbers and types of coronavirus-targeting antibodies for up to 1 year. By contrast, he says, twice-vaccinated people stop seeing increases “in the potency or breadth of the overall memory antibody compartment” a few months after their second dose. For many infectious diseases, naturally acquired immunity is known to be more powerful than vaccine-induced immunity and it often lasts a lifetime. [Source:]

    How does that fit with data coming out of NSW and Victoria showing the Jabbed are ending up in hospital?

    In Victoria only 5% of those in hospital are unjabbed. Of the rest, 78% are fully jabbed and the rest, partially jabbed. Surely the Jab must play a part?

    In the UK similar things are happening with more people sick and dying as Jab rates get higher. Also Singapore. Who would know if it is ADE?

    You’re reading data incorrectly. It is the other way around. Sometimes an official or two mis-speak on TV and the such errors go viral. You’ve got to do your research – there are enemies of the truth on all sides.
