Gap between first and second doses of Covid vaccines
Dear Editor,
Dr Chaand Nagpaul, BMA Council chair, was on national news today (23.01.21) saying that the gap between first and second doses of Pfizer Covid vaccine should be halved from 12 weeks to 6 weeks.
I suspect he has not read the BMJ interview article (BMJ 23rd January) with Andrew Pollard, leader of clinical trials of AstraZeneca Covid vaccine. Answering a question about dose interval, Professor Pollard says that a longer dose interval seems to provide a better immune response because the immune system has been given time to mature. He is referring to vaccines in general, not just the Oxford one.
