How does AstraZeneca's trial pause affect other COVID-19 vaccines? Analysts weigh in

The development could result in four possible scenarios, SVB Leerink's Andrew Berens wrote to clients early Wednesday. If the event is determined to not be transverse myelitis or not linked to the AstraZeneca vaccine, the program could proceed after a delay of weeks to months, he wrote. But if transverse myelitis is confirmed as a reaction to the vaccine, the program would be “terminated,” Berens wrote. And under two other scenarios linking transverse myelitis to the SARS-CoV-2 virus or COVID-19 infection, other vaccine players would naturally be affected.
