Two months after the first Covid-19 vaccines received U.S. clearance, the shots’ efficacy is holding up well in the real world, according to a study among more than 31,000 people immunized in four states.
The report, one of the first large-scale studies to assess how vaccines are performing in practice, used artificial intelligence software to scan the medical records of early vaccine recipients at Mayo Clinic facilities. The findings are important because vaccine and drug efficacy in the real world often differs from what is seen in the carefully controlled environment of experimental clinical trials.
