According to the British Medical Journal
The Pfizer and BioNTech covid-19 vaccine may provide some early protection, starting 12 days after the first dose, the peer reviewed results of a phase III trial have found.
The study, published in the New England Journal of Medicine, found that vaccine efficacy between the first and second doses was 52% (95% credible interval 29.5% to 68.4%), with 39 cases of covid-19 in the vaccine group and 82 cases in the placebo group.
Seven or more days after the second dose, vaccine efficacy then rose to 95% (90.3% to 97.6%), with eight covid-19 cases reported in the vaccine group and 162 cases in the placebo group.
So Rosie Cooper MP has questioned the NHS vaccine 12 week policy.
She has “pushed the Government for further evidence to back up the decision to delay the Covid vaccine second dose to the 12 week limit”.
Rosie is a member of the Parliamentary Health Select Committee and has written to the Chief Medical Officer and Health Secretary to ask for detailed justification for this delay, and the scientific evidence behind it.
This follows a number of medical professionals speaking out about this decision, specifically the policy to administer the Pfizer second dose at 12 weeks instead of the recommended three, as they feel it goes against the true results of the trials.
She commented “I am deeply concerned by the NHS and Government’s commitment to the policy of insisting that the second dose of the Pfizer vaccine is administered after 12 weeks, without evidence to back this up.
“We continue to be told that the first dose gives 90% effectiveness, and that all the second dose does is increase this by 5%. If this is absolutely true, then why is this not a one dose vaccine?
“Other scientists have suggested that analysis of the Pfizer study shows the opposite, that the second dose in fact turbocharges the moderate immunity achieved by the first.
“The health service is trapped in the NHS England directive and is forced to continue to stand by this policy which I believe in a short time will be seen to have more holes than a Swiss cheese. Having met with the Medical Director for UK Vaccines at Pfizer, I was left with absolutely no doubt that they are against this!
“Already people are contracting Covid more than three weeks after their first dose. I am worried that this was a decision that the Government and NHS are now too committed to go back on. More needs to be done to investigate the repercussions of this hastily reached decision before it is too late!”
