FDA says that two doses of Mederna vaccine are adequate for protection and may not require the third dose.
The Food and Drug Administration issued a document on October 12 stating that after analyzing the data submitted by Mederna, it was found that two doses of the vaccine still provided protection against severe illness and death.
The document pointed out that although the third dose of the vaccine can induce sufficient antibody response, the number of antibodies produced before and after the injection is not much different, and it does not meet all the conditions for approval of the booster.
The Food and Drug Administration’s committee will discuss on the 14th whether to approve Mederna’s application for the third injection. The committee generally follows the recommendations of the expert group.
For example, the committee has rejected Pfizer’s third shot vaccine plan, but in the end the FDA still recommends the third shot, and expands to include people who are exposed to work or life in high-risk environments , Such as medical staff and grocery store employees.
Mederna applied to the FDA to increase the authorization of the booster on September 1. Mederna said that clinical studies have shown that using half the dose as the third booster is safe and has a stronger immune response than the second injection in its phase III clinical trial.
Moderna warns: Canadians need to get the third shot before Christmas
According to Canadian Global News, Stephen Hoge, President of Moderna, warned that during this Christmas period, Canada’s fully vaccinated people will have more “breakthrough” infections, which means that more adults need to be vaccinated before the end of the year. The third shot of vaccine.
Like the Pfizer vaccine, a study by Mederna showed that over time, the antibodies in the vaccinated person’s body will begin to gradually weaken about 6 months after the second injection. In addition, the fourth wave of the epidemic caused by the Delta variant led to a surge in cases, among which many fully vaccinated patients had breakthrough infections.
This prompted Mederna to call for booster shots for adults who have been fully vaccinated.
