mRNA don’t need ultra cold fridges any more.

Also, even if, you don’t need fridges, you need boxes with dry ice, that is relatively cheap.

As for the price - you’re sure it’s $60 not $30? Regardless, you’re right that it’s an issue.

Pfizer I think it's like $20 a shot (need 2), Moderna $30 or so, at least at this stage when they can't make them fast enough

There's also Novavax which only needs to be refrigerated.

Well this isn't ideal, its not like this means the vaccine is useless.

No vaccine is 100%. They don't have to be to be useful.

Study only talked about mild-moderate cases of one specific variant. Well i would like it to work across the board, working well against the other variants and preventing severe cases of the problematic variant, is still a win, even if a qualified one.

they mean that a person who thinks they are vaccinated is more dangerous than one who doesnt, because they change their behavior

Yes, but it doesn't follow that someone with this vaccine is more dangerous than someone without one. The result of this study is not that this vaccine is totally useless, just that its not ideal. There is big gap between what is reported here and having nothing. Its still likely to be beneficial.
