Study finds that vaccine booster doses increase the chances of getting COVID-19

The Cleveland Clinic was surprised by the results of its own research: "increased risk of COVID-19" with more vaccine doses "was unexpected."

The Cleveland Clinic published a revealing and troubling study on the efficacy of the COVID-19 vaccine and booster doses. According to the research, antibody boosters may increase the likelihood of contracting coronavirus.

The health center screened more than 50,000 of its employees to test the "bivalent" vaccine, which is supposed to protect people from the original COVID-19 strain and Omicron variant. However, after evaluation, it was found that these vaccines were only 30% effective in preventing infection against the different variants of the virus.

The effectiveness of booster doses, which are meant to increase the duration of antibodies, was also analyzed. The Cleveland Clinic paper exposed that there may actually be an increased risk of contracting coronavirus depending on the number of vaccinations received.

"The association of increased risk of COVID-19 with higher numbers of prior vaccine doses in our study, was unexpected," the research indicates.

Experts at the health say data shows that those who received more doses are more likely to contract the disease.

Some 45% of people in the study opted to receive fewer than three vaccines despite recommendations about keeping up to date with boosters, and it was precisely that group who was at the lowest risk, according to the study.

"One could reasonably expect these individuals to have been more likely to have exhibited higher risk-taking behavior. Despite this, their risk of acquiring COVID-19 was lower than those who received a larger number of prior vaccine dose", the research notes.

Adverse effects of the Pfizer vaccine

In addition to the possibility of boosters' ineffectiveness, another recent study reported that Pfizer's coronavirus vaccine may be causing adverse effects, especially in people over the age of 65.

Researchers at the Food and Drug Administration (FDA) revealed that the vaccine appears to be linked to blood clotting.

Pfizer's vaccine could cause pulmonary embolism, lack of oxygen to the heart, intravascular coagulation and a blood platelet disorder known as immune thrombocytopenia.

While both studies appear to need further investigation, the findings are not only surprising but also of great concern to the world's population.
