“Booster shots of the Pfizer-BioNTech and Moderna vaccines lose substantial effectiveness after about four months.”
QUICK FACTS:
- The effectiveness of Pfizer’s and Moderna’s mRNA gene therapy drug declines substantially after four months, according to a study published Friday by the Centers for Disease Control and Prevention (CDC).
- The CDC authors said the vaccine was 91% effective in preventing a vaccinated person from being hospitalized during the two months after a booster shot, but after four months, protection fell to 78%.
- Protection faded more in preventing trips to urgent care and emergency departments, falling from 87% in the first two months to 66% after four months, WaPo notes.
- After more than five months, vaccine effectiveness fell to roughly 31%.
- Researchers noted that their numbers are “imprecise because few data were available.”
FAUCI SAYS THE VACCINE’S WANING EFFICACY MEANS WE NEED TO TAKE MORE OF IT:
- “There may be the need for yet again another boost — in this case, a fourth-dose boost for an individual receiving the mRNA — that could be based on age, as well as underlying conditions,” Fauci said.
- The National Institutes of Health, comprised in part of the National Institute of Allergy and Infectious Diseases (NIAID), whose director is Dr. Fauci, owns part of the patent for the Moderna vaccine.
BACKGROUND:
- Waning immunity after a third shot of mRNA vaccine during omicron has been observed in Israel and in preliminary reports from CDC, WaPo notes.
- The European Union’s health agency on Feb 11 said is it investigating reports of certain COVID-19 vaccines being linked to menstrual cycle changes, The Epoch Times reports, as several recent studies have found women who got vaccinated experienced menstrual cycle disruptions.
- The safety committee of the European Medicines Agency (EMA) has launched “an in-depth evaluation of all available data, including reports from spontaneous reporting systems, clinical trials and the published literature.”
