A next generation Covid vax has been authorized by a major drug regulator for the first time.
It's a self-amplifying mRNA vax by Arcturus (USA), which could be more durable. It's authorized in Japan - with an application lodged in Europe, too.
Efficacy seems similar or superior efficacy to BNT/Pfizer vax.
Also in this update post @PLOS:
- Some trials of mucosal vax fully recruited or close
- Preclinical research highlights for "variant-proof" & pancoronavirus vaxes
