The corporate launched information in late December that discovered two doses of its vaccine triggered a powerful immune response in opposition to the unique omicron variant, although three doses gave the impression to be higher. As well as, in late Might, the corporate introduced it started a scientific trial to check an up to date vaccine designed to focus on the omicron variant.
Manufacturing for a modified vaccine that incorporates the BA.5 subvariant might start later this summer season, Erck stated, with photographs in arms starting in November or December, pending authorization from regulators.
Novavax’s vaccine could also be linked to a small however elevated threat of myocarditis, in response to an FDA briefing doc. Pfizer’s and Moderna’s vaccines have been related to the guts irritation situation, notably in younger males, although the complication stays uncommon.
