The number of people receiving a first dose of the UK-made jab has already ground to a halt, with just 100,000 dished out last month compared to 2million per week in March. Around 3m Britons are still waiting on their second jab, but the Government has shortened the gap between doses to eight weeks, which means most of should get the follow-up injection this month.
MailOnline has analysed data from the Medicines & Healthcare products Regulatory Agency, which provides a weekly update on how many doses of each brand was deployed.
Only people over the age of 40 are being offered AstraZeneca due to its link to rare but deadly blood clots in the young, which has seen its demand tumble since spring. Over-40s have been coming forward for the jab since April.
The MHRA data shows two million first doses of AstraZeneca were being injected into arms per week in March before slowing to 300,000 in May. But just 100,000 first doses were deployed during the entire month of June.
In total, 24.6m people had received their first AstraZeneca vaccine by June 30, the latest week for which data is available, and 21.5m had been fully vaccinated. It leaves 3.1m still to receive their second shot.
Officials are administering 800,000 second doses of the British vaccine each week, which could see the remaining AstraZeneca patients protected by the end of this month.
It comes after the Department of Health said that another 96,000 first and 175,000 second doses were dished out on Thursday. The latest figures mean 45.7m people are at least partially protected — or 86 per cent of adults — and 34.4m are fully immunised (65 per cent).
