Whereas there was a small imbalance of instances within the vaccine group in contrast with the placebo, the FDA stated it isn’t sure whether or not the drug contributed to the paralysis “as a result of the variety of instances was small and less frequent than anticipated within the common inhabitants.”
“There have been no different notable patterns or numerical imbalances between remedy teams for particular classes of adversarial occasions, together with different neurologic, neuro-inflammatory, and thrombotic occasions, that may counsel a causal relationship to the Moderna COVID-19 vaccine,” FDA workers wrote within the paperwork.
