2 coronavirus vaccine trials resume final-stage testing after pauses
Two drug manufacturers have announced the resumption of late stage COVID-19 vaccine trials in the United States after temporary pauses over safety incidents. AstraZeneca resumed its trial on October 23rd, and Johnson & Johnson is doing so early in the week of October 26th. Safety pauses are not uncommon in large trials, as regulators and other safety experts seek to determine if adverse events were caused by the drug or vaccine being tested or are coincidental.
