The whole thing is ludicrous. This strategy also applies to the Pfizer vaccine. By having the booster further apart, it lowers its efficacy from over 90% to around 80%. Given the mistakes the UK government has made along the way, this just fills me with further dread for the situation (I have family there).

- deanclatworthy 6y agoI would agree if this was for the general population but consider the most vulnerable are being vaccinated first. They should be treated with great care and priority and I think it’s unethical for the UK to lower their chances, especially considering the huge numbers of vaccines they are going to have over the coming weeks.
