Pfizer, Moderna COVID Vaccines May Increase Risk of Infection, Study Shows, by Megan Redshaw

So, you’re likely to Covid if you have had a Pfizer or Moderna vaccine than if you haven’t. Quite an endorsement for those vaccines. From Megan Redshaw at childrenshealthdefense.org:

A peer-reviewed study in the New England Journal of Medicine shows two doses of an mRNA COVID-19 vaccine yield negative protection against symptomatic SARS-CoV-2 infection, while previous infection without vaccination offers about 50% immunity.

A new peer-reviewed study shows two doses of an mRNA COVID-19 vaccine yield negative protection against symptomatic SARS-CoV-2 infection, while previous infection without vaccination offers about 50% immunity.

The findings, published June 15 in the New England Journal of Medicine (NEJM) analyzed information from more than 100,000 Omicron-infected and non-infected residents in Qatar from Dec. 23, 2021, through Feb. 21, 2022.

The authors compared the effectiveness of the Pfizer and Moderna COVID-19 vaccines, natural immunity from previous infection with other variants and hybrid immunity (a combination of infection and vaccination) against symptomatic Omicron infection and severe, critical and fatal disease.

Researchers found those who had a prior infection but had not been vaccinated had 46.1% and 50% immunity against the BA.1 and BA.2 Omicron subvariants more than 300 days after the previous infection.

However, individuals who received two doses of the Pfizer and Moderna vaccines, but had not been previously infected, had negative immunity against the BA.1 and BA.2 Omicron subvariants — indicating an increased risk of infection compared to someone without prior infection and vaccination.
