AstraZeneca Plc’s (NYSE: AZN) coronavirus vaccine development program could hit by further delays, as the Food and Drug Administration has widened the scope of its probe into the halted trial, Reuters reported Wednesday.What Happened: The federal agency is inquiring whether side effects similar to the one seen in the COVID-19 vaccine trial — transverse myelitis — also emerged in trials of other vaccines designed by Oxford University, AstraZeneca’s partner, Reuters said, citing people familiar with the matter. The vaccines reportedly under review use a modified adenovirus as a vector and target illnesses such as the Middle East Respiratory Syndrome and the flu.Oxford’s vaccines use a chimpanzee adenovirus, ChAdOx1, unlike other vaccine developers that use a human variant. A review of research papers by Reuters found that in one trial, a serious side effect event cited by researchers was classified as unrelated to the vaccine.Another complication that may affect the trial: the Reuters report said the FDA is requesting data from the British pharmaceutical firm that is in a different format than the one used by the FDA. People familiar with the developments told Reuters the FDA’s actions aren’t an indicator there are safety issues related to any of the vaccines under review.Benzinga is covering every angle of how the coronavirus affects the financial world.
