’V-Day’ as Britain starts mass Covid-19 vaccination

A 90-YEAR-old grandmother became the world's first person to receive a fully-tested Covid-19 shot on Tuesday, as Britain began mass vaccinating its people in a global drive that poses one of the biggest logistical challenges in peacetime history.

Health workers started inoculating the most vulnerable with the vaccine developed by Pfizer and BioNTech, with the country a test case for the world as it contends with distributing a compound that must be stored at -70C (-94F).

Margaret Keenan, who turns 91 in a week, was the first to receive the shot, at a hospital in Coventry, central England.

"It's the best early birthday present I could wish for because it means I can finally look forward to spending time with my family and friends in the new year after being on my own for most of the year," she said.

The launch of the vaccine, one of three shots that have reported successful results from large trials, will fuel hope that the world may be turning a corner in the fight against a pandemic that has killed more than 1.5 million people.

Britain, the worst-hit in Europe with over 61,000 deaths, is the first Western nation to begin mass-vaccinations and the first globally to roll out the Pfizer/BioNTech shot.

But despite the relief of people receiving the first dose of the two-dose regimen, they will have to wait three weeks for their second shot, and there is no evidence immunisation will reduce transmission of the virus.

"It will gradually make a huge, huge difference. But I stress gradually, because we're not there yet. We haven't defeated this virus yet," Prime Minister Boris Johnson said.

Health Secretary Matt Hancock said he expected millions to be vaccinated by the end of the year, and described the start of the drive as "V-Day". But he cautioned people should respect social-distancing rules until spring at least, when he hoped the most vulnerable people would be vaccinated.

The country has ordered enough supplies of the Pfizer/BioNTech shot to vaccinate 20 million people. The developers said it was 95% effective in preventing illness in final-stage trials.

Russia and China have both already started giving domestically produced vaccine candidates to their populations, though before final safety and efficacy trials have been completed.

FIVE DAYS IN A FRIDGE

In Britain, about 800,000 doses are expected to be available within the first week, with care-home residents and carers, the over-80s and some health workers prioritised. Hancock said he had a "high degree of confidence" Britain would take delivery of another batch of the vaccine next week.

The country is relatively small with good infrastructure. Yet the logistical challenges in distributing the vaccine, which only lasts five days in a regular fridge, mean it will first go to dozens of hospitals and cannot yet be taken into care homes.

Bigger tests could await for the Pfizer/BioNTech shot, as well as a vaccine from Moderna, which was found to have a similar level of success in trials and is based on the samem RNA genetic technology that requires such ultra-cold storage.

Transport and distribution could prove more challenging in hot countries and bigger nations such as the United States and India, which have been worst-hit by Covid-19 and are expected to approve the shot for emergency use in the coming days or weeks.

South Korea, which has coped relatively well with the pandemic, sounded a note of caution, saying it would not hurry vaccine roll-outs, partly to give it time to observe potential side-effects in other countries. Vaccinations may start in the first half of 2021, the health ministry added.

The third vaccine to have had trial success, developed by AstraZeneca and Oxford University, is viewed as offering one of the best hopes for many developing countries because it is cheaper and can be transported at normal fridge temperatures. Late-stage trials found it had an average success rate of 70%.

UK Chief Scientific Adviser Patrick Vallance said vaccines that were easier to store and deploy would play a key role. Britain hopes for regulatory approval of the Oxford/AstraZeneca vaccine in the next couple of weeks.

BREXIT 'ADDS COMPLEXITY'

Britain approved the Pfizer/BioNTech vaccine for emergency use less than a week ago, and is rolling it out ahead of the United States and European Union, from which it will finally part ways at the end of the year.

The Brexit transition period ends on December 31, and there is the possibility of chaos at ports, with military aircraft on standby to step-in.

The Pfizer/BioNTech vaccine is being imported from Belgium,while initial supplies of the AstraZeneca/Oxford shot are being shipped from Germany.

"Of course, it adds complexity," Steve Bates, chief executive of the BioIndustry Association, told reporters of the possible impact of Brexit. "But there is a robust plan for alternative routes and mitigation."

In total Britain has ordered 40 million doses of the Pfizer/BioNTech shot. As each person requires two doses, that is enough to vaccinate 20 million people in the country of 67million.

The country has ordered 357 million doses of seven different Covid-19 vaccines in all.
