Everyday I get more depressed at the way our home governments are handling this crisis. What concerns me about the change of tack with vaccines is that what they are doing is unproven, and this mass vaccination programme, the biggest the UK has ever done is going against the recommended dose regimes of the manufacturers. The experts have defended the action by saying that the data supports a 12 week interval between doses. There is some evidence that it does for the AZ vaccine, although its not what AZ recommend. There is no evidence for the Pfizer vaccine. In clinical trials 52% get a response from first dose, but Pfizer or anyone else doesn't know how long it lasts as the second jab was given at 3 weeks and showed a 95% long lasting response. The Vaccine experts went back to the Pfizer data and said one dose gives a 90% response and they are confident it will last 12 weeks ( but no evidence).
The 90% figure was obtained by extracting from the data all those patients who tested positive or showed symptoms within 10/14 days after the jab as they would not have built up an immunity. In real life what they say is rubbish because there will always be people who will get Covid shortly after having a jab.
50 million people will be vaccinated in UK, we know both vaccines work well when given at recommended dose intervals. Yet we are going to do it on a wing and a prayer with an unproven dose regime. Lord help us
