Covid immunity is ‘lasting well’ for most people who are double jabbed and a mass booster programme is not necessary, a top Oxford scientist said.
Professor Dame Sarah Gilbert – o
ne of the leading figures in the development of the Oxford AstraZeneca vaccine – suggested extra shots should be directed to countries with a low rate of immunisation.It comes a day after Health Secretary Sajid Javid said he expects a booster programme to start later in September, though he is still awaiting advice from experts on the scale of any campaign.
The Medicines and Healthcare products Regulatory Agency (MHRA) has said the Pfizer and AstraZeneca jabs are safe to use as boosters, but the Joint Committee on Vaccination and Immunisation (JCVI) has yet to give its recommendations to ministers.
Dame Sarah told The Daily Telegraph that the elderly and people with weakened immune systems should be in line for a third jab but ‘I don’t think we need to boost everybody’.
‘As the virus spreads between people, it mutates and adapts and evolves, like the Delta variant,’ she said.
‘With these outbreaks, we want to stop that as quickly as possible.
‘We will look at each situation; the immunocompromised and elderly will receive boosters.
‘But I don’t think we need to boost everybody. Immunity is lasting well in the majority of people.’
Dame Sarah’s comments echo a warning from the boss of AstraZeneca earlier this week, who said giving booster jabs to everyone may put unnecessary pressure on the NHS this winter.
Pascal Soriot urged the government to wait until there was more data on immunity from people who have been double jabbed for six months.
But ministers are determined to get the ball rolling to avoid any more restrictions over autumn.
On Thursday, Mr Javid said, ‘we are heading towards our booster programme’ in England but he wanted the ‘final opinion of the JCVI’.
‘I’m confident that our booster programme will start later this month but I’m still awaiting the final advice,’ he added.
Dame Sarah has previously highlighted the wide disparity in vaccination rates between different countries, suggesting jabs should be sent to those areas where availability is low to vaccinate everybody once, rather than some people three times.
She stressed this again in her interview with The Telegraph.
‘We need to get vaccines to countries where few of the population have been vaccinated so far,’ she said.
‘We have to do better in this regard. The first dose has the most impact.’
The JCVI is expected to give its advice on who should receive a booster shot within days.
It has already said a third dose should be offered to people with severely weakened immune systems.
The expert panel is looking at the latest data from the Cov-Boost trial run by the University Hospital Southampton.
The £19.3 million UK clinical trial is testing the Pfizer jab alongside those from AstraZeneca, Moderna, Novavax, Janssen from Johnson & Johnson, Valneva and CureVac.
The study is answering key questions such as whether vaccine doses can be ‘mixed and matched’ and who needs the booster.
The new MHRA guidance says Pfizer boosters can be given to anyone, regardless of which doses they had previously.
However, AstraZeneca boosters will only be given to those who previously had the AstraZeneca jab.
The latest Government data showed that up to September 8, 48,344,566 people have received a first dose of vaccine, a rise of 25,131 on the previous day, while 43,708,906 have received both shots, an increase of 87,960.
The Government said a further 167 people had died within 28 days of testing positive for Covid-19 as of Thursday, bringing the UK total by that measure to 133,841.
As of 9am on Thursday, there had been a further 38,013 lab-confirmed Covid-19 cases in the UK, the Government said.
