There are 30 candidate vaccines (probably a lot more by now). 32 if you include the two that are non-weakened forms of virus that are being proposed for variolation.

Are these 2 others actual registered trials? Or are you referring to public proposals for such, like Hanson's?

I'm working on just such a public proposal [1] and have been in correspondence with Hanson but haven't heard of any registered.

Having "candidate vaccines" is very different from having a "vaccine". Variolation is a reasonable alternative to the lack of a known, effective vaccine.

Variolation as a term only applies to smallpox. Giving small doses of the live virus as hanson suggests is literally just a lame vaccine. It's also not known to be safe or effective and would have to go through all the trials anyway.

Hanson is saying we should do those trials, not that we should start deliberately infecting the masses ASAP. The issue is that such trials are banned.
