Novavax had a rough week on the stock exchange last week due to manufacturing issues (which is surprising as rumors of severe quality issues are directed at Moderna and Pfizer as well). They had initially projected a US roll out in 3rd qtr 2021, but with the recent issues pushed in to Jan 2022. This is supposedly a traditional vaccine formulation. For those with a religious exemption to the mRNA shots, Novavax initially had no fetal cell use, but this summer there were reports that they decided to test using abortion-derived fetal cells (bummer if true).
I've seen reports that Moderna and Pfizer both use lucifervase in their shots (not just the boosters). Since they are EUA, they are not required to provide full disclosure of ingredients yet, so there are "fact finders" who will dispute the use.
