Lots of articles out this weekend regarding the logistics and cost to the government of getting the vaccine out to the people who need it, particularly if a two part vaccine is the winner. Besides supplies, training workers, delivery and storage, being able to find, notify, and get people to the vaccine will be challenging. Front line workers are easy, as they are already at points of service, but the elderly and at-risk (who should be some of the first to get vaccinated) are not. Making sure everyone gets their second dose adds a serious second level of complexity.
