The emergence of the B.1.617.2 coronavirus variant has led some scientists to call for the reopening to be delayed.
United Kingdom Prime Minister Boris Johnson has said the country would accelerate its COVID-19 vaccination programme to try to contain a fast-spreading variant first identified in India that could knock a reopening of the economy off track.
The UK has delivered one of the world’s fastest inoculation campaigns, giving a first shot to almost 70 percent of the adult population and a second to 36 percent, helping to reduce infection rates and deaths.
“It’s more important than ever, therefore, that people get the additional protection of a second dose,” he told a news conference on Friday.
“So following advice from the Joint Committee on Vaccination and Immunisation, we will accelerate remaining second doses to the over 50s and those clinically vulnerable right across the country, so those doses come just eight weeks after the first dose,” he said.
The emergence of the B.1.617.2 variant in parts of northern England and London has prompted some scientists to call for the reopening to be delayed, and a rethink on the speed of the vaccine rollout.
“I believe we should trust in our vaccines to protect the public whilst monitoring the situation very closely because the race between our vaccination programme and the virus may be about to become a great deal tighter,” Johnson told a news conference.
The spread of the variant could disrupt Britain’s progress out of lockdown, making it more difficult to move to the final stage of a staggered reopening of the economy in June.
“It’s very clear now we’re going to have to live with this new variant of the virus for some time so let’s work together, and let’s exercise caution and common sense,” he said.
Johnson had aimed to lift all restrictions on June 21, after allowing people in England from Monday to hug again, meet in small groups indoors and travel abroad.
Chris Whitty, England’s chief medical officer, said there was now confidence that B.1.617.2 was more transmissible than the variant first discovered in Kent that fuelled England’s second wave of infections. He said B.1.617.2 could come to dominate in Britain.
Public Health England said on Thursday there had been 1,313 cases in England of B.1.617.2 in a week, more than double the previous week’s figure, with four confirmed deaths.
Whitty said so far there had not been a significant increase in hospitalisations from the variant, which may be because more people had been vaccinated.
But both Johnson and Whitty said it was still early days, and scientists would need to scrutinise data over the next two or three weeks to truly see the effects of the variant.
The UK put India on a travel “red list” in April, meaning all arrivals from India – now suffering the world’s most severe wave of COVID-19 – would have to pay to quarantine in a government-approved hotel for 10 days.
Media reports at the time suggested that, because the quarantine requirement was announced four days in advance, many people had sought to fly beforehand. The UK has a large South Asian community.
Even with new variants, the government is likely to want to avoid repeating the regional curbs used last year, which ultimately failed to prevent two further national lockdowns.
At the national level, infections are still low and fell for a fifth consecutive week in England, Office for National Statistics (ONS) figures showed on Friday.
