The Johnson & Johnson COVID-19 vaccine has been authorized by the Western States Scientific Safety Review. The group — comprised of public health experts from California, Nevada, Oregon and Washington — was created last year to independently review the safety and efficacy of any coronavirus vaccine approved by the FDA before any distribution occurs in those states. Their decision on the latest vaccine comes after the FDA and CDC granted their initial authorization for the vaccine. The state is expecting 320,000 doses vaccine next week.
