And I Think It's Going to be a Long, Long Time

There is renewed speculation, that 2nd doses of Covid-19 vaccine, could now be given to patients in England, more than 12 weeks after the first ( People running the programme hope, by doing this, to vaccinate more of younger cohorts more quickly (vaccine supplies are very limited). It has been claimed that the level of protection seen, after the first injection, actually improves with time (having said that, the evidence is a bit vague and UK government advice still stresses the need for patients to get their 2nd jab to acquire 'full' protection). The vaccines were approved on the basis of their efficacies and safety, using the injection schedules employed in their trials (there was generally a 3 week period between the 1st and 2nd injections). I still wonder, if it is premature to alter the spacing between the doses, this early in the mass vaccination process. We are still finding out information about these novel preparations. The changes might also damage public confidence in the vaccines.
