Delta variant has wrecked hopes of herd immunity, warn scientists
There is no way of stopping Covid spreading through the entire population, experts tell MPs as they call for end of mass testing
The delta variant has wrecked any chance of herd immunity, a panel of experts including the head of the Oxford vaccine team said as they called for an end to mass testing so Britain can start to live with Covid.
Scientists said it was time to accept that there was no way of stopping the virus spreading through the entire population, and monitoring people with mild symptoms was no longer helpful.
Prof Andrew Pollard, who led the Oxford vaccine team, said it was clear that the delta variant can infect people who have been vaccinated, which made herd immunity impossible to reach even with high vaccine uptake.
It comes as Angela Merkel became the first major world leader to announce the end of free testing, with the provision set to stop in Germany from Oct 11.
On Tuesday, the Department of Health confirmed that more than three quarters of adults have now received both jabs, and calculated that 60,000 deaths and 66,900 hospitalisations have been prevented by vaccination. But experts said it would never be
Speaking to the all-party parliamentary group on Covid, Sir Andrew said: "Anyone who is still unvaccinated will, at some point, meet the virus.and 17-year-olds should be vaccinated was because it may help prevent a winter Covid wave.
"We don't have anything that will stop transmission, so I think we are in a situation where herd immunity is not a possibility and I suspect the virus will throw up a new variant that is even better at infecting vaccinated individuals."
Until recently, it was hoped that increasing the number of Britons jabbed would create a ring of protection around the population. As late as last week, the Joint Committee on Vaccination and Immunisation said one of the reasons it had advised that 16
However, analysis by Public Health England has shown that when vaccinated people catch the virus they have a similar viral load to unvaccinated individuals and may be as infectious.latest data is suggesting that two doses is probably only 50 percent protective against infection."
Paul Hunter, professor in medicine at the University of East Anglia and an expert in infectious diseases, told the committee: "The concept of herd immunity is unachievable because we know the infection will spread in unvaccinated populations and the
Prof Hunter, who advises the World Health Organisation on Covid, also said it was time to change the way the data was collected and recorded as the virus became endemic.ourselves with very high numbers that actually don't translate into disease burden."
"We need to start moving away from just reporting infections, or just reporting positive cases admitted to hospital, to actually start reporting the number of people who are ill because of Covid," he added. "Otherwise we are going to be frightening
On Tuesday, Sajid Javid, the Health Secretary, confirmed that third dose booster shots would be given from next month. However, Sir Andrew argued that, if mass testing was not stopped, Britain could be in a situation of continually vaccinating thepopulation.
"I think as we look at the adult population going forward, if we continue to chase community testing and are worried about those results, we're going to end up in a situation where we're constantly boosting to try and deal with something which is notmanageable," he said.
"It needs to be moving to clinically driven testing in which people are willing to get tested and treated and managed, rather than lots of community testing. If someone is unwell they should be tested, but for their contacts, if they're not unwell thenit makes sense for them to be in school and being educated."
Dr Ruchi Sinha, consultant paediatrician at Imperial College Healthcare NHS Trust, told MPs and peers that choosing not to vaccinate children would be unlikely to cause problems in the health service.and those children are already considered for vaccination. Covid on its own in paediatrics is not the problem."
"What matters is the burden of patient hospitalisation and critical care and actually there hasn't been as much with this delta variant," she said. "They tend to be the children who have got their comorbidities, obesity, or severe neurological problems

Evidence is also mounting that it is capable of infecting fully vaccinated people at a greater rate than previous versions, and concerns have been raised that they may even spread the virus, these experts said.
In Singapore, where Delta is the most common variant, government officials reported on Friday that three quarters of its coronavirus cases occurred among vaccinated individuals, though none were severely ill.
Israeli health officials have said 60% of current hospitalized COVID cases are in vaccinated people. Most of them are age 60 or older and often have underlying health problems.
