A recent study funded by Pfizer has found that only the company's most recent Comirnaty mRNA COVID shot is effective in preventing symptoms of COVID-19. The study, which has not been peer reviewed, revealed that people who received any previous version of Comirnaty had similar outcomes as unvaccinated individuals.
Published on December 28, 2023, the study found no benefit for recipients of past Comirnaty shots. The updated Comirnaty booster specifically targets the Omicron XBB 1.5 strain of the SARS-CoV-2 virus, which is already on the decline in the United States. However, the researchers determined that previous Comirnaty doses do not protect against hospital admission, emergency room or urgent care visits, or outpatient visits in any meaningful way. In fact, certain individuals who received the older Comirnaty doses even had a higher risk of hospital admission.
Infectious disease epidemiologist Sara Tartof, PhD, MPH, and co-authors of the study noted that compared to the unvaccinated, those who had received only older versions of COVID-19 vaccines did not show a significantly reduced risk of COVID-19 outcomes, including hospital admission.
Interestingly, marketing campaigns for the initial deployment of the experimental Comirnaty shot heavily emphasized that getting vaccinated would reduce one's risk of hospitalization from COVID-19. However, the latest study does not confirm the accuracy of that message. In fact, people who received at least two doses of older Comirnaty shots actually had a higher risk of outpatient visits and were more likely to be hospitalized with acute respiratory illness, particularly in certain age groups.
Some doctors speculate that Pfizer's goal in funding this study with negative findings for older Comirnaty shots is to encourage increased uptake of the newest Comirnaty shot. Currently, only 14 percent of Americans have received a COVID booster shot. Israeli immunologist Ehud Qimron, MD, believes conflicts of interest may be present, stating that the study reveals a strong bias that could potentially influence the reported results.
The mRNA COVID shots are not the only public health measure that has proven to be ineffective and even harmful to the public. The conclusions of the Pfizer-funded Comirnaty study revealing that the vaccinated had similar outcomes to the unvaccinated come shortly after former director of the National Institute of Allergy and Infectious Diseases, Anthony Fauci, MD, testified in Congress that the six-feet social distancing guidelines had no scientific basis.
Despite the study's findings, World Health Organization (WHO) officials continue to urge people to get COVID shots, claiming that it will lessen the pressure on healthcare systems dealing with rising hospitalizations for respiratory infections. Maria Van Kerkhove, PhD, the WHO's interim director of epidemic and pandemic preparedness, expressed concern over the “incredibly low” flu and COVID vaccination rates in many countries this season.
