Covid: Boosters not needed for all, says Oxford jab creator Covid: Vaccine protection still strong - Oxford jab creator
(about 4 hours later)
Prof Dame Sarah Gilbert said extra doses should be used to boost immunity in countries with low vaccination rates Professor Dame Sarah Gilbert: "We need more doses so we're not talking about choices"
Giving booster jabs to everyone is unnecessary, says the scientist behind the Oxford vaccine, as she calls for doses to be sent to countries in need. The vaccines are still providing strong protection, a year on from the initial two doses, says the scientist who developed the Oxford-AZ vaccine.
Prof Dame Sarah Gilbert told the Daily Telegraph some vulnerable groups would need boosters but immunity was "lasting well" in the majority of cases. The UK's vaccine advisory body is set to decide whether booster doses against Covid-19 are needed this autumn.
"We need to get vaccines to countries where few of the population have been vaccinated so far," she added. Prof Dame Sarah Gilbert told the BBC that offering a third booster dose to millions of people was "a complex decision".
The UK vaccine advisory body is due to give its final advice on boosters soon. And she called for more vaccines to be licensed to increase supplies.
The Joint Committee on Vaccination and Immunisation (JCVI) has already said a third dose should be offered to people with severely weakened immune systems, which accounts for up to half a million people in the UK. The Joint Committee on Vaccination and Immunisation (JCVI) has already said a third top-up dose should be offered to people with severely weakened immune systems, which accounts for up to half a million people in the UK.
But it has not decided if they are needed more widely, and who should be eligible. But it has not decided if booster doses are needed to extend protection in larger numbers of people at high risk from Covid-19, including those normally eligible for a flu jab.
Health Secretary Sajid Javid said on Thursday he was awaiting "final advice" from the JCVI but was "confident" a booster programme would start later this month.
Interim advice issued by the JCVI in July suggested more than 30 million people should receive a third dose, including all adults over 50.
The UK medicines regulator (MHRA) has approved the use of Pfizer and AstraZeneca as Covid booster vaccines, paving the way for a rollout ahead of the winter.

Vaccinologist Dame Sarah, who began designing the Oxford-AstraZeneca vaccine in early 2020 when Covid first emerged in China, said the decision over boosters needed to be looked at carefully. Prof Gilbert, who began designing the Oxford-AstraZeneca vaccine in early 2020 when Covid first emerged in China, said there were no signs of immunity waning in ongoing trials of the vaccine, which started in April 2020.
She told the Telegraph: "We will look at each situation; the immunocompromised and elderly will receive boosters. Blood tests on volunteers who had been vaccinated more than a year ago, showed they had signs of good protection.
"But I don't think we need to boost everybody. Immunity is lasting well in the majority of people." "It's the first dose of the vaccine that has the most impact, whoever you give that vaccine too," she said.
However, she said the UK needed to help more countries around the world with vaccine supply. "We have to do better in this regard. The first dose has the most impact." "We get good protection after a single dose and then it's improved by a second dose and we would expect to see it being maintained or possibly slightly improved then by third dose.
"As we would expect, with any other vaccine, we are seeing strong maintenance of the [immune] response."
'More doses needed'
Prof Gilbert also said the world needed more doses and more vaccine supplies, so there didn't need to be a choice between vaccinating one country over another.
"More doses are becoming available and we need to focus on getting those doses to countries that really need them," she said, adding that many African countries had only vaccinated 2% of their population.

He told BBC Radio 4's Today programme the UK had a "moral obligation" to help other countries, adding: "There is such a big risk, morally from our perspective - there's a risk to trade, there's a risk to economies, but also these are our friends and colleagues who need to be protected and we are losing them every day that goes by."

Sir Andrew also said the UK still had high levels of protection from the virus, despite the fall in levels of people's immune response after having had the vaccine. The JCVI needs to look at the issue of who is ending up in hospital after being infected as part of its considerations, he added.Sir Andrew also said the UK still had high levels of protection from the virus, despite the fall in levels of people's immune response after having had the vaccine.
