Dr Hilary has revealed how protected you are following the first dose of the Pfizer vaccination.

The TV Doctor explained the reasoning behind the delay and tried to allay any fears people have about the longer 12-week gap between vaccine doses.

It comes after criticism from a number of corners following the decision to delay the second jab with many fearing the first dose would be rendered useless.

Speaking to Susanna Reid on Good Morning Britain, Dr Hilary explained how the vaccine worked and why this decision has been taken.

He said: “So the data that was published by the manufacturer themselves suggested the first dose gives you 52 percent immunity before the second dose which they wanted to be given three weeks afterwards.

“The joint committee on vaccinations and immunizations modelled the extrapolated if you like, the likely immunity using the data, the same data that Pfizer published and suggested that by missing the second dose and delaying it to 12 weeks after the first dose you get 89% immunity.

“So I think it was right to also say looking at the Pfizer data, looking at the modelling, it was probably the right thing to do in the UK where you’ve got an overwhelming numbers of people going into ICU and on ventilators that we give the maximum protection that we can expect to the maximum number of people in the minimum amount of time.

“I think it will be controversial and there are no certainties and there is lots I didn’t say about how long immunity lasts because we simply don’t know, this is a new vaccine but by and large it’s a decision that was made by the JCVI (Joint Committee on Vaccination and Immunisation) in conjunction with the four chief medical officers of the UK and it’s something that other countries around the world are looking at doing as well.

“So we made a decision on public health measures trying to protect the maximum number of people as quickly as possible.”
