Imported coronavirus variants are unlikely to set lockdown easing back to “square one” because immunity from vaccines “won’t just disappear”, according to a key figure on the UK’s immunisation committee.
Professor Adam Finn, a member of the Joint Committee on Vaccination and Immunisation (JCVI), said he expected a “gradual erosion” of vaccine protection as the virus evolves but not enough to “scupper” the Prime Minister’s road map, as one leading scientist had predicted.
On Friday, Imperial College’s Danny Altmann said “we should be terribly concerned” after 77 cases of a potentially vaccine-busting Covid-19 mutation first discovered in India were identified in Britain.
“They (variants of concern) are things that can most scupper our escape plan at the moment and give us a third wave. They are a worry,” Professor Altmann told the BBC.
Prof Finn said he thought the immunology expert had been “a bit pessimistic” with his assessment.
“We’ve all expected evolution of this virus to occur from the start,” he told Times Radio.
“I also think that we know from other viruses and previous experience that the immunity that vaccines give won’t just disappear.
“It will be a gradual erosion. It won’t be back to square one. I would be really surprised if that happened.
“So, I think, possibly, that interpretation is a bit pessimistic.”
Prof Altmann said he found it “mystifying” and “slightly confounding” that those flying in from India were not required to stay in a hotel, with the virus soaring in the south Asian country.
India is not currently on the Government’s “red list” for travel, which sees people who have been in those countries in the previous 10 days refused entry to the UK.
British or Irish nationals, or people with UK residency rights, are able to return from red list countries but must isolate in a quarantine hotel for 10 days.
Prof Finn said, with the pandemic “raging” in places such as India – which recorded more than 217,000 cases in 24 hours on Friday – and Brazil, international travel would continue to pose a “problem”.
On Saturday, the global death toll from Covid-19 topped three million, according to the Johns Hopkins University’s count.
“We’re going to need to continue to be really quite careful,” Prof Finn continued, “to avoid moving the virus around, so I think travel won’t go back to normal yet.”
A Downing Street spokesman told reporters that the Government’s red list of travel ban countries is “under constant review”, when asked why India did not feature on it.
No 10 said Mr Johnson’s visit to India “is still happening later this month” but, as already announced this week, would be “slightly shorter” than the initial four-day planned trip, with most of the meetings expected to be shoehorned into a single day.
It comes as the latest figures showed a continuing decline in Covid cases in the UK, with England recording its lowest infection rate in seven months.
On Saturday, the Government said a further 35 people had died within 28 days of testing positive for Covid-19, while a further 2,206 lab-confirmed cases of the virus had been recorded in the UK.
More than 600,000 additional daily vaccine jabs were also administered, according to the latest Government data up to April 16, with 485,421 of them second doses.
With non-essential retail permitted to open stores to customers on a weekend for the first time since January, a sector chief said there had been a “really positive” uplift in trade since Covid regulations were relaxed on Monday as part of the Prime Minister’s road map.
Helen Dickinson, chief executive of the British Retail Consortium, told BBC Radio 4’s Today: “It certainly started really well.
“From a retail point of view, people really did come out and support their local businesses and all the retailers I’ve spoken to said those first few days of the past week or so had been really positive in terms of trading.”
Despite warnings from police to stay away from Windsor due to Covid restrictions still banning large gatherings, hundreds of royal fans turned up to pay tribute to the Duke of Edinburgh during his funeral on Saturday afternoon.
