Is there any website where we can track the development of "better vaccines"? For example India approved needle free (hypospray!) vaccine Zycov D.

I've found [1] to be a good resource for this.

But I'd not consider it a valuable source for tracking the progress.

Edit: It's also from 2021-12-08 - probably way too old to be meaningful, a lot of knowledge has been acquired since then.
