THURSDAY, March 25, 2021 (HealthDay News) — Following a sharp rebuke from an independent oversight board over potentially misleading information on the effectiveness of its COVID-19 vaccine, AstraZeneca released new data late Wednesday that showed the vaccine is slightly less effective than the company claimed on Monday.<\/p>\n
The pharmaceutical giant stressed that its vaccine is still very powerful at preventing infection with COVID-19, based on more recent data than were used when the company first announced the interim results of its U.S. clinical trial.<\/p>\n
After saying that the vaccine was 79 percent effective on Monday, the company said Wednesday that the vaccine was 76 percent effective at preventing COVID-19.<\/p>\n
“The [latest] primary analysis is consistent with our previously released interim analysis, and confirms that our COVID-19 vaccine is highly effective in adults, including those aged 65 years and over,” Mene Pangalos, Ph.D., executive vice president of BioPharmaceuticals R&D at AstraZeneca, said in a company news release. “We look forward to filing our regulatory submission for Emergency Use Authorization in the U.S. and preparing for the rollout of millions of doses across America.”<\/p>\n
