The news suggests they are delaying the second dose, or at least strategising. If there isn't enough vaccine to go around (which there isn't) giving people the recommended 2nd dose is also a gamble. > The UK’s strategy to delay the second dose of both ... vaccines is so that more people can be vaccinated with their first dose rather than giving a smaller number of people both doses. The hope is that this will save more lives -- https://blogs.bmj.com/bmj/2021/01/20/revisiting-the-uks-strategy-for-delaying-the-second-dose-of-the-pfizer-covid-19-vaccine/ https://blogs.bmj.com/bmj/2021/01/20/revisiting-the-uks-stra... Do you think the advantage of the 1st vaccine is less than that of the 2nd? i.e that it is better to have 1 person with the recommended 2 vaccines, and another with no vaccinations; versus, two people with only the first vaccination.

That's the point, they are delaying the second dose. The original vaccine tests were based on 2 doses 3 weeks apart. It's a big gamble that it won't lead to more vaccine resistant strains.

  And is allowing current strains to spread further because there isn't enough vaccine not a gamble? I'm also not sure there is a big problem: "Neither bacteria nor viruses evolve resistance to vaccines as easily as they do to drugs, they wrote.
