Health services in the UK today (January 4) marked the first anniversary of the deployment of the Oxford University/AstraZeneca vaccine in fight against Covid-19. Exactly a year ago, the UK became the first country in the world to administer the vaccine by jabbing Brian Pinker, 82 at Oxford University Hospital. So far, around 50 million AstraZeneca vaccines have been administered to people in the UK. Commenting on the landmark day, vaccines minister Maggie Throup said: "The Oxford-AstraZeneca vaccine is a UK success story and demonstrates what can be achieved when researchers, scientists and the government work together. "The at-cost vaccine has given billions of people around the world a way to fight back against this virus." Further, she urged people to get vaccinated to protect themselves and their families this winter.

Prince Charles formally opened a new 1 billion pound AstraZeneca research and development (R&D) facility in Cambridge on Tuesday (November 23), as the company aims to fuel the growth of its drug pipeline. AstraZeneca has supplied two billion doses of its Covid-19 vaccine, developed at Oxford University, and is also looking to bring a preventative antibody cocktail against Covid-19 to market. Prince Charles, son of Queen Elizabeth and heir to the throne, saw an exhibit on the pandemic and a demonstration of how augmented reality headsets can help with lab work, before hearing about the company's net-zero targets. "The last two years have been some of the most difficult of a generation," Prince Charles said in a speech.

The British scientist who led the research underpinning AstraZeneca's coronavirus vaccine said at the weekend that a new jab could be developed against the emerging Omicron variant "very rapidly" if needed. Professor Andrew Pollard, director of the Oxford Vaccine Group, also said existing vaccines should work against the new strain, but that would only become apparent after more research in the coming weeks. "It's extremely unlikely that a reboot of a pandemic in a vaccinated population like we saw last year (with the Delta variant) is going to happen," he told BBC radio. But if required, "The processes of how one goes about developing a new vaccine are increasingly well-oiled, so if it's needed that is something that could be moved very rapidly." In a statement, AstraZeneca said it had "developed, in close collaboration with Oxford University, a vaccine platform that enables us to respond quickly to new variants that may emerge".

The University of Oxford on Tuesday said there was no evidence that vaccines would not prevent severe disease from Omicron, but that it was ready to rapidly develop an updated version of its vaccine developed with AstraZeneca if necessary. Earlier on Tuesday, the head of drugmaker Moderna said that Covid-19 shots were unlikely to be as effective against the variant, jolting global markets. The University of Oxford said that there was limited data on Omicron so far, and that it would carefully evaluate the impact of the variant on its shot, echoing an AstraZeneca statement last week. "Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease and there is no evidence so far that Omicron is any different," it said in a statement.

Future pandemics could be even more lethal than Covid-19 so the lessons learned from the outbreak must not be squandered and the world must ensure it is prepared for the next viral onslaught, one of the creators of the Oxford-AstraZeneca vaccine said. "The truth is, the next one could be worse. It could be more contagious, or more lethal, or both," Prof Dame Sarah Gilbert said in the Richard Dimbleby Lecture, the BBC reported. "This will not be the last time a virus threatens our lives and our livelihoods." Gilbert, a professor of vaccinology at the University of Oxford, said the world should make sure it is better prepared for the next virus. "The advances we have made, and the knowledge we have gained, must not be lost," she said. Efforts to end the Covid-19 pandemic have been uneven and fragmented, marked by limited access to vaccines in low-income countries while the "healthy and wealthy" in rich countries get boosters, health experts say.
