Which old tech vaccines? I haven't seen any attenuated vaccines for covid. Even the viral vector vaccines aren't exactly "old tech" and they are certainly less effective than mRNA vaccines.

Just like with mRNA; viral vector vaccines haven't been seen widespread use before COVID either. And the only attempts at an attenuated vaccine have been pretty ineffective as far as I know.

They're all pretty comparable. Novavax should be getting a lot more attention since it doesn't require super cold storage and appears to be on par with the mRNA vaccines.

Novavax does look promising, but I was mainly pointing out that there is currently no effective "old tech" vaccine in widespread use, it's all new tech.

I'm not saying that out of skepticism for these vaccines, I think it's amazing we're deploying all these new platforms. I just think saying that they're no more effective than vaccines we've had before is a misrepresentation of the facts.
