A peer-reviewed paper published by the Journal of the American Medical Association concluded that immunity against the omicron coronavirus variant fades rapidly after a second and third dose of the Pfizer-BioNTech vaccine.

The research by Danish scientists published in JAMA Network Open on Friday found antibody responses fell within weeks after second and third Pfizer doses, Forbes reported.

A newly published long-term study by the prestigious British journal The Lancet that followed up on participants in the Moderna and Pfizer trials found the vaccines had no effect on overall mortality.

An analysis of CDC data by Dr. Meryl Nass found vaccinated Californians and New Yorkers were three times more likely to develop COVID than those who had prior immunity and were unvaccinated.

Further, vaccinated Californians had a higher rate of hospitalizations than those who were unvaccinated but had prior immunity. New York did not provide hospitalization data.

In April, the Food and Drug Administration released a briefing document that says the composition of the current COVID-19 vaccines might need to be changed to ensure high levels of protection.
