Was thinking that once we vaccinate those at most clinical risk of acute symptoms from CV19 maybe we target those at a higher risk of infection. That is those with the greatest number of varied interactions.

So we protect the vulnerable, then try to create choke points to reduce spread. This does rely on the data that indicates vaccines reducing infectivity are correct. So hospitality workers, shop keeps/store workers, police, teachers (and related), students and so on. Some will be in the vulnerable groups others in other priority groups but we do want to prevent any "typhoid Mary" types.

I guess part of the problem there is defining the groups accurately and the data is less accurate and more variable than age and clinical need.
