Dr Hilary on why second dose of the Covid vaccine is delayed – Kent Live

Dr Hilary has revealed the reason that the second doses of the coronavirus vaccine are being delayed – and it’s so more people can receive their first jab.

The first Covid vaccine, developed by Pfizer and Biontech, was given to the first patient, 90-year-old Margaret Keenan, on December 8.

Recommendations when it was first approved were for the second dose of the two-dose jab to be given within three weeks.

But now the time has been extended, and in a letter released last week, the UK’s chief medical officers said the time between the first and second dose has now been extended to 12 weeks.

“The JCVI is confident 12 weeks is a reasonable dosing interval to achieve good longer-term protection,” it read.

Now, Dr Hilary Jones has shared the thinking behind the decision to delay the second dose.

He appeared on Good Morning Britain today opposite Piers Morgan.

Dr Hilary warned: “The situation changes rapidly.

And the new variant has undoubtedly changed the data and the thinking over the virus.

“Is it better – if you have two grandparents, for example – is it better to vaccinate one twice? And give them very very good immunity against Covid-19?

“And not to vaccinate the other one at all? So they have no protection?

“Or do you give them both one dose and give them very very good protection?”

Piers replied: “Well how much protection? How much protection are we actually talking about?

“Can I feel safe whatsoever – safe at all – with one dose of the jab? What is the data? What is the percentage?”

Dr Hilary replied: “Well, yes, you are. The data suggests you are anywhere between 75 per cent and 89 per cent with one dose.

“That is actually very good. So by waiting the extra few weeks for the second dose, you are able to protect far greater numbers of people with just one dose.

“And logically and scientifically, as well as medically, that has to be right. It is hugely inconvenient and distressing for people to have their second dose cancelled.

“I understand that. But there is a science behind it.”
