It has been revealed the fact that the 4th vaccine dose shows negative efficiency against COVID death. Check out the following reports about this below.
4th vaccine dose has no efficiency against COVID death
According to a recent peer-reviewed study, a fourth dose of the COVID-19 vaccine may not be as effective as anticipated.
The study was a retrospective population-based observational study published in the European Journal of Clinical Investigation. It utilized national health data from the Austrian epidemiological reporting system, individual all-cause mortality data from Statistics Austria, and the national COVID-19 vaccine registry.
Researchers analyzed COVID-19 deaths and SARS-CoV-2 infections in 3,986,312 individuals between Nov. 1 and Dec. 31, 2022. They compared the outcomes of 281,291 individuals who received four vaccine doses with 1,545,242 individuals who received three vaccine doses to determine relative efficacy.
The CDC measures the relative effectiveness of different COVID-19 vaccines by comparing people who received one vaccine to those who received a different one. In a recent study, researchers found that during the initial study period, there were 69 COVID-19 deaths and 89,056 SARS-CoV-2 infections. The overall case fatality rate was 0.08 percent.
However, when comparing those who received four vaccine doses to those who received three, researchers found that the relative vaccine efficacy was negative 24 percent.
Furthermore, the study found that there were more COVID-19 deaths among individuals who received four vaccine doses than among those who received fewer doses or no vaccinations at all.
“Negative efficacy basically means [there were] more deaths (or illnesses) in the vaccinated group compared to the unvaccinated group. Efficacy is a “delta” of unvaccinated deaths minus vaccinated deaths. Once vaccinated deaths exceed unvaccinated deaths, the delta becomes negative, and that yields a negative efficacy,” Brian Hooker, chief scientific officer at Children’s Health Defense, who holds a doctorate in biochemical engineering, told The Epoch Times in an email.
During the initial study period, over 80 percent of vaccinated Austrians had received Pfizer’s COVID-19 vaccine.
Individuals who received four vaccine doses had a 17 percent reduced risk of infection; however, this decreased risk rapidly diminished and reversed itself during a six-month extended follow-up.
As a result, people who received four doses had a higher risk of infection than those who received fewer doses. Interestingly, those with repeated previous and recent infections experienced significantly reduced reinfections, regardless of the vaccine dose.
In the extended observation, 97.4 percent of individuals who had received four vaccine doses had received Pfizer’s vaccine.
