“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 could infect people who had 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 had been prevented by vaccination. But experts said it would never be enough to stop Covid from spreading. 

Speaking to the all-party parliamentary group on Covid, Sir Andrew said: “Anyone who is still unvaccinated will, at some point, meet the virus. 

“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 and 17-year-olds should be vaccinated was because it may help prevent a winter Covid wave.

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.

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 latest data is suggesting that two doses is probably only 50 percent protective against infection.”

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.

“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 ourselves with very high numbers that actually don’t translate into disease burden.”

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 the population.

“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 not manageable,” 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 then it 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.

“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 and those children are already considered for vaccination. Covid on its own in paediatrics is not the problem.”

Readers Comments:

Exact opposite: the Delta variant is ensuring TRUE natural population immunity, where less than 15% of the population will be at risk of serious infection throughout most of Europe in the coming 1-2 months. Delta is accelerating natural immunity in Europe so that the winter should have minimal Covid spread.

Already Sweden and the Czech Republic appear to have reached that final goal.  The Netherlands, Slovenia, Lithuania, UK, France, Spain, Belgium and Portugal should follow in about 1-2 months, without the need of any more vaccination.

“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.”

So Nancy Pelosi was wrong all last year when she said “testing, testing, testing, testing and more testing“. And contact tracing is a waste of resources.Yet still no money spent on funding T-cell testing, much less allowing Early Treatment.

“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 ourselves with very high numbers that actually don’t translate into disease burden.”

“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.”

Yes, if Big Pharma is allowed to create a Delta based vaccine and push mass Delta boosters, all 2.5 Billion people will soon find their prior double-jab worthless.  If instead a Delta vax was limited to only very high risk, presenting with a negative T-cell test, then maybe some lives could be saved without resulting in further SARS-Cov-2 escape mutations.

None of the above talk is allowed in the USA.  We live in the Peoples Republic of Fauci.

I met someone from Australia on Monday, who is applying for permanent residence, at this time, only because she compares current Australia to the old Soviet Union. Despite being double Pfizer vaxxed, she would otherwise face severe travel restrictions.   Her friend works at NIH, and although he only knows only a fraction of the truths, says that fellow NIH people joke that Fauci should be “locked up in his basement”.
