COVID-19 vaccines can prevent diseases for up to 3 years, Operation Warp Speed ​​official said

With the first coronavirus vaccine recently approved for emergency use and currently being rolled out to the country’s medical workers, Dr. Moncef Slaoui said the injections could provide protection against COVID-19 disease for up to three years.

Operation Warp Speed’s chief medical advisor Slaoui told MSNBC’s Andrea Mitchell on Tuesday that vaccines will provide long-term protection.

“My expectation is that the prevention of disease through these vaccines will take quite a long time, maybe the prevention of infection at the level we see, maybe shorter, maybe three, four, six months,” Slaoui said of “Andrea Mitchell Reports. . “” When prevention of disease, in my humble opinion as an expert, is likely to take a year or two, three years. “

Meanwhile, the Food and Drug Administration Committee of Pfizer and Moderna jabs, the latter of which is pending regulatory approval, says it is unclear what impact the vaccines will have on SARS-CoV-2 transmission, among other unknown factors, due to limited data.


The FDA has also noted that “the available data on the Pfizer-BioNTech COVID-19 vaccine administered to pregnant women is insufficient to inform the risks associated with the vaccine during pregnancy.” The same goes for children under the age of 16.

“We know that there is a clear benefit expected to immunize pregnant women,” Slaoui continued. “In all fairness, the expectation is that it should be okay, but it’s important to document and study it before labeling.”

The Operation Warp Speed ​​official added that Johnson & Johnson plans to limit recruitment on Thursday, with an expected readout of the efficacy data in early January.

“We expect an application, if everything goes according to plan and if the vaccine is effective, sometime very late in January 2021, and an approval in February, with FDA approval,” Slaoui continued.
