The scientist behind the AstraZeneca Covid-19 vaccine has voiced his concerns about the booster jabs. Dr Andrew Pollard, who also chairs the UK’s Joint Committee on Vaccination and Immunisation, said that it was “unsustainable” to vaccinate people with boosters twice a year.

In an interview with the Telegraph, Pollard said that injecting people with booster shots every four to six months is unsustainable. He said: “We can’t vaccinate the planet every four to six months. It’s not sustainable or affordable. [If] your goal [with boosters] is to stop all infections, that is wrong.”

Pollard said that vaccine rollouts should “target the vulnerable” instead of boosting entire populations. “The future must [focus] on the vulnerable and make boosters or treatments available to them [in order] to protect them,” he added.

Additionally, the scientist, who is from the University of Oxford, said that additional booster vaccines beyond the third should be put on hold unless there is “strong evidence” that they are required. He commented on the issue of a fourth vaccine as other countries have forced them on the masses.

“We know that people have strong antibodies for a few months after their third vaccination. But more data [is] needed to assess whether, when and how often those who are vulnerable will need additional doses,” he said.

The AstraZeneca vaccine has been linked to blood clots and other adverse reactions, resulting in some countries temporarily halting the use of the jab.

In the same interview, Pollard added that he is “not a huge fan” of compulsory vaccination. He instead suggested that clearer information is a better way to convince people to get vaccinated. “[Compulsory vaccination] would make more sense in some Eastern European countries, where a quarter of the population is vaccinated,” he explained.

The scientist has classified unvaccinated people into three groups: Those unable to physically access clinics, those who are hesitant, and those who are anti-vax. He thinks that the “relatively small and young” second group could benefit from a “conversation with community leaders or a trusted person” such as a GP.

Pollard said that the staunch “anti-vaccine” group “may hold unshakable views and [may] be harder to impact.” He added that he is troubled by the supposed “misinformation” spread by people who belong to this group.

“Misinformation risks people’s lives. It’s highly likely that people became seriously ill and died because of vaccine misinformation.”
