Yes, but if the “may, might, should” applies to cheap and easily accessible & tested drugs/shots beneficial for other things —> then that’s helpful for those who are still on edge about the newer, experimental vaccines. Especially if in the age group or health status that has a promising outcome against the virus to begin with.
No arguments from me.
Just that there is not a lot known and a whole lot of policies are now being built around the “may, might and should”
Mask might help ... so lets require everyone to wear a mask. Vaccines might not be harmful but lets require them anyway. Other drugs might work...
etc
