I find this a compelling argument: New data favour administering COVID-19 vaccines as fast as possible, not reserving doses; I agree with Alex Tabarrok's short post: Wise Canadians:
The second dose, Dr. McGeer and other experts agree, is crucial to ensuring immunity lasts as long as possible. They say everyone should get the second dose on schedule, but if supply issues delay that injection by a week or two, it shouldn’t hamper how well the vaccines work.
I, of course, am not a medical professional, nor am I trained in any of the relevant disciplines.
Just a very interested observer and participant in the worldwide experiment.
