Britain’s coronavirus vaccine drive is working, with the first published real-world data today showing both jabs currently being deployed cut the risk of being hospitalised by the illness by up to 95 per cent.
Researchers examined coronavirus hospital admissions in Scotland among people who had had their first jab and compared them with those who had not yet received a dose of either vaccine.
Results showed the Pfizer and Oxford/AstraZeneca jabs slashed the risk of hospital admission from Covid by up to 85 and 94 per cent, respectively, four weeks after the first dose.
Experts from the universities of Edinburgh and Strathclyde, as well as Public Health Scotland, claimed the data provided ‘compelling evidence’ that both vaccines cut the risk of being hospitalised.
Lead researcher Professor Aziz Sheikh said: ‘These results are very encouraging and have given us great reasons to be optimistic for the future. We now have national evidence – across an entire country – that vaccination provides protection against Covid-19 hospitalisations.
‘Roll-out of the first vaccine dose now needs to be accelerated globally to help overcome this terrible disease.’
The promising findings, which mirror data coming from Israel’s world-beating roll-out, comes after the UK’s vaccines ministers Nadhim Zahawi today said evidence that the jabs curb transmission — as well as prevent severe illness — ‘looks good’.
He told Sky News: ‘We wouldn’t be in this place this morning to be able to say that we’re going to reopen schools on March 8… if we’re not confident that actually the vaccine programme is beginning to really bear fruit.’
Boris Johnson is set to unveil the national ‘roadmap’ out of lockdown today, with all schools reopening from March 8 but precious few other easings until Easter.
The roadmap, which runs to around 60 pages, is set to include modelling supporting the government’s tentative strategy. It will be published alongside more positive news about the effectiveness of jabs in reducing transmission.
Nadhim Zahawi said the Government would not be looking to ease lockdown restrictions if they weren’t confident the first dose of the vaccine had driven down hospitalisations and deaths from the virus among the over-70s
The first real-world evidence of the jab roll-out in Scotland is based on data from the 1.14million doses dished out between December 8 and February 15.
Around 650,000 people in Scotland had been given the Pfizer/BioNTech vaccine, while almost 500,000 had received the Oxford/AstraZeneca jab.
Researchers analysed hospital data over the 10-weeks – including GP records on vaccination, hospital admissions, death registrations and laboratory test results.
The team, whose results have yet to be peer-reviewed, compared the outcomes of those who had received their first jab with those who had not.
It showed that among those aged 80 and over — one of the highest risk groups — vaccination was associated with an 81 per cent reduction in hospitalisation risk in the fourth week, when the results for both vaccines were combined.
Although the leaked findings are lower than the 100 per cent efficacy shown in Oxford’s original trial, top scientists today insisted the results were encouraging.
Efficacy is always higher in controlled studies because researchers use more young and healthy people to make the trials run smoothly and quickly.
And the data is from people given just one dose of a vaccine. Data shows the jabs are more effective when a top-up is given up to 12 weeks later.
Older people — who are at the front of the queue for vaccines because they are most vulnerable — have weaker immune systems.
Dr Jim McMenamin, National Covid Incident Director at Public Health Scotland, said: ‘These results are important as we move from expectation to firm evidence of benefit from vaccines.
‘Across the Scottish population the results shown a substantial effect on reducing the risk of admission to hospital from a single dose of vaccine.
‘For anyone offered the vaccine I encourage them to get vaccinated. We are continuing our evaluation and look forward to describing the benefits that we hope will follow the second doses of these vaccines.’
Dr Josie Murray, from Public Health Scotland, added: ‘These data show real promise that the vaccines we have given out can protect us from the severe effects of Covid.
‘We must not be complacent though. We all still need to ensure we stop transmission of the virus, and the best way we can all do this is to follow public health guidance – wash your hands often, keep two metres from others, and if you develop symptoms, isolate and take a test.
‘We also all need to protect ourselves, our families and friends by taking the second dose of vaccine when it is offered.’
Mr Johnson’s plans for easing lockdown have been bolstered by the latest data whihc shows Covid-19 infection rates have continued to drop, with 9,834 more cases reported – a fall of 10 per cent on last week – while the 215 new daily deaths brought Britain’s total up to 120,580
Professor Chris Robertson, an epidemiologist at the University of Strathclyde, said: ‘These early national results give a reason to be more optimistic about the control of the epidemic.
‘They also show the value of linked national data sets with academic research groups working closely with public health institutes.’
Professor Chris Whitty, Chief Medical Officer for England, said the study ‘provides encouraging early data on the impact of vaccination on reducing hospitalisations’.
Professor Fiona Watt, executive chair of the Medical Research Council, which helped fund the study, said: ‘The discovery of very high protection before the second dose of the vaccines is very welcome news.
‘These promising early results are a testament to the extraordinary efforts of the everyone who worked so hard to develop the vaccines and roll them out with unprecedented speed, and to these researchers who’ve analysed Scottish health data in near real-time.’
Separate Public Health England data expected to be published today will be the first time officials have released figures they say show the jabs are cutting transmission among the over-70s.
Top scientists have so far stuck to a cautious tone, claiming they are expecting to see the roll-out reduce hospitalisations and deaths ‘any minute now’.
Others said last week, however, they were seeing ‘early signs’ of their impact on these key measures.
Health Secretary Matt Hancock said yesterday the first dose was reducing transmission by two-thirds.
Britain is dishing out almost 400,000 doses a day on average — as it races to inoculate the top nine priority groups who are most at risk from the virus.
Almost a third of all adults in the UK have now been vaccinated, or 17.5million.
Mr Zahawi added on BBC Breakfast today that once the over-50s are covered the Government will ‘absolutely’ follow the recommendations of its scientists in expanding the rollout.
‘The Joint Committee on Vaccination and Immunisation (JCVI) are looking at that and we will absolutely follow what they recommend,’ he said.
‘The recommendation for phase one has been correct because it’s based on clinical assessment of who is most vulnerable to be hospitalised or have serious infection and sadly death in some cases.
‘So we’ll go back to the JCVI and they will make that recommendation and we will follow that recommendation.’
Reports suggest the committee will recommend the drive continues by age groups, meaning over-45s would be next in line.
Every adult in Britain could have received their vaccinations by July, according to reports.
It comes as Mr Johnson faced growing Tory backlash today over his ‘cautious’ route out of lockdown – with schools opening on March 8 but precious few other easings until Easter.
The plan will be unveiled this afternoon after it is rubber-stamped by Cabinet – with scientists seemingly having won the battle for a slow approach despite surging vaccinations.
The first steps to freedom will prioritise getting children fully back into classrooms in a fortnight’s time, while people will also be able to meet one friend or family member in the park for a coffee or picnic from March 8.
But the next stage of loosening will not be until March 29, when the Rule of Six will make a comeback – and to be extended to allow two households to gather, enabling relatives to meet properly for the first time in months.
Tennis courts and golf courses will also be allowed to open on this date, along with the return of grassroots football.
The plan will run the gauntlet of angering the Tory benches this afternoon.
Former chief whip Mark Harper, chair of the 70-strong Tory Covid Recovery Group, said: ‘Keeping restrictions in place ”because a new variant may come along in the future” is a recipe for never unlocking. Ever.’
