Agreed, but it was given a temporary emergency approval due to the pandemic. We need long term data on technologies before we immunize hundreds of millions of people with it.

Huh? How many millions have been immunized so far with it?

What question did you have for me? I see your comment as a statement.

The point is clear you said

> We need long term data on technologies before we immunize hundreds of millions of people with it.

But we have already done this, hundreds of millions of people have received the mRNA vaccines.

We don't have long term (5+ years) data though, which was my point. It was authorized as an emergency measure due to the pandemic.

Sure, but maybe the flu isn't the best example. I'm long MRNA and big fan of the vaccine's technology. It was a biochem nerd dream getting my first shot!
