Pfizer Inc. said that data from the U.S. and Israel suggest that the efficacy of its Covid-19 vaccine wanes over time, and that a booster dose was safe and effective at warding off the virus and new variants.
The company detailed the data in a presentation it will deliver to a meeting of outside advisers to the Food and Drug Administration on Friday.
The panel is expected to make recommendations for whether more Americans should receive booster shots.
“Real-world data from Israel and the United States suggest that rates of breakthrough infections are rising faster in individuals who were vaccinated earlier,” Pfizer said in its presentation, which was posted on the FDA website. The drug giant is partnering with Germany’s BioNTech SE to make the shots.
