What info I •have• been able to find:
- Novavax seems to involve fewer/milder side effects for many
- It’s approximately as effective as the mRNA ones
- At 95 days since last booster, I’m now into the period of waning efficacy
So my loose conclusion is: “No harm in the mix and match, maybe some benefit and maybe not.”
If there’s more I should know, either to bolster or to contradict that, I’d love to hear it!
