This article discussed the study published by Lancet two days ago that showed that previous SARS-CoV-2 infection protects against re-infection. It is a large study considering it included 65 studies from 19 countries. The result showed that previous infection is highly protective against the Wuhan type, which they called ancestral, and the alpha, beta, and…
This article talks about a new preprint study from Oxford University showing that a COVID-19 breakthrough infection provides better and longer protection than a booster shot. A breakthrough infection is a COVID-19 infection in those with COVID-19 jabs. In the investigation, the authors compared whether a third or booster shot or a breakthrough infection following…
The study, Comparison of the immunogenicity of BNT162b2 and CoronaVac COVID-19 vaccines in Hong Kong, was published in the peer-reviewed journal Respirology. The two injections are different. The Pfizer BNT162b2 uses the modified RNA technology enclosed in a lipid nanoparticle. In contrast, the Coronavac uses an old vaccine technology using inactivated viruses that cannot replicate…

The media and health agencies have conditioned the population that variants are dangerous. The discovery of the Delta and omicron variant has led governments to push for more vaccinations, whether first, second dose, booster, or further boosters. They also use it as an excuse to vaccinate children who don’t need it. The paper, Intra-host variation and…
A FaceBook friend asked me what is the chance of reinfection if you recovered from COVID-19. A quick search revealed many studies that show a low risk of infection. I answered her and made this article. The studies are listed in no particular order. Emphasis added. 1. Re-infection Rates among Patients who Previously Tested Positive…
Dr. Angelique Coetzee of South Africa is credited with discovering the omicron variant among her patients. ABC Radio National interviewed Dr. Coetzee about the omicron cases that she has seen. She said most have mild symptoms like fever, fatigue, headaches, body aches, and nausea. No one showed symptoms commonly seen with the Delta variant: “No…
