(AP) Two drugmakers announced Friday the resumption of U.S. testing of their COVID-19 vaccine candidates.
Testing of AstraZeneca’s vaccine candidate had been halted since early September, while Johnson & Johnson’s vaccine study was paused at the beginning of last week. Each company had a study volunteer develop a serious health issue, requiring a review of safety data.
The two coronavirus vaccines are among several candidates in final-stage testing, the last step before seeking regulatory approval.
The drugmakers said they got the go-ahead Friday from the Food and Drug Administration to restart tests in the U.S.
