Just thinking out loud here (positive thought), might be miles off or numbers might be insignificant but still...
We know that first vaccine doses are having a much lesser effect in reducing transmission/symptoms etc.
But I ask, what about people who have had *prior infection* who are receiving their first dose? I wonder, would that then act in a similar manner to a previously uninfected person getting their 2nd dose?
As the younger age groups are the ones most likely to have been already infected, asymptomatic or otherwise, I wonder if this could help us transmission wise once they start getting their first dose. So in a sense, hope is not all lost for the first doses.
If that makes any sense. As I say, just a thought, with no scientific expertise behind it!
