What we need is greater supply (especially Pfizer), i think the vast majority of people are willing but are as yet unable to get vaccinated.
This push to reduce interval for AZ (to 4 to 6 weeks) seems to be very short sighted, yes it increases
efficacy in the short term but is still reduced by 10-20% compared to the 8-12 week interval - even the UK with their covid rate did not reduce the dose interval to what we are doing (in some cases).
