鲍威尔患有其他疾病, including Parkinson’s and the blood cancer multiple myeloma, which could hamper 恢复 from COVID-19 infection, 根据 报告. His family didn’t specify when Powell received vaccine, or whether he had taken a booster shot.
“The vaccines that we have, 和他 [鲍威尔] evidently was fully vaccinated, are extraordinarily good against preventing death, hospitalization and severe disease but they are not perfect,” 博士. Greg Poland, infectious diseases expert at the Mayo Clinic, 告诉福克斯新闻, adding that depending on patients’ age, gender and underlying medical conditions, 取决于 5% will not be fully protected.
“That is the very reason that we are engaging now in a national dialogue about booster doses,” Poland said. Regulators last month authorized a booster dose of the Pfizer-BioNTech COVID-19 vaccine for adults ages 65 及以上, and people ages 18-64 at high risk of exposure and severe COVID-19 disease. An FDA advisory committee endorsed a similar authorization for Moderna’s half-dose booster shot, and also recommended all adults ages 18 and older who received the single-shot Johnson & Johnson vaccine at least two months ago receive a second shot.
“The shot works. This is not evidence that the shot doesn’t work,” 博士说. 马克·西格尔, Fox News medical contributor and professor of medicine at NYU Langone Health. “This is an outlier but it’s a wake up call for boosters.”
Several medical experts, 包括博士. Aaron Glatt, chair of the department of medicine at Mount Sinai South Nassau, told Fox News that older adults and high-risk populations should receive booster vaccines to increase their protection.
“If any good could come out of this, it’s a warning to all that booster doses have their place, particularly in the more elderly, or frail or people with underlying medical conditions,” Poland said. “As soon as they can get their booster, they should.”
