Yeah it definitely seems less risky than the mRNA/adenoviral-vector approach. I know a guy in the Phase 3 trials who had some really bad side effects from the shots, but they only lasted a day. Unfortunately now he's stuck because the mandates all require one of the authorized vaccines, and there's essentially no data on whether it would be safe for him to take one after Novavax.

I have heard of companies accepting Novavax trial participants as meeting the mandate requirements. Might be worth asking.

Or if he is needing a booster shot... yeah, that's a little harder right now. I think some trial participants (in England?) were approved for taking a different vaccine as a booster, but if can possibly hold out, waiting for more Novavax seems to make more sense to me.

The CDC guidelines explicitly state clinical trial participants are ok for the mandate. My company has a mandate and I’m fine since I was part of the AstraZeneca trial.
