A Pfizer-BioNTech Covid-19 vaccine is administered as part of the global vaccine rollout. The timetable outlined this week divided those eligible for the vaccine, those 16 and over, into four groups. These sections of the population have borne the brunt of lockdowns more than the rest of us and understandably feel vulnerable. Offering some one-dose and some two-dose vaccines sounded like a recipe for a logistical nightmare, in terms of ensuring the right people got the right vaccination at the right time. "Do it once, do it right" should be the mantra here.
