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.

Covid-19 vaccine makers are shifting gears and planning for a smaller, more competitive booster shot market after delivering as many doses as fast as they could over the last 18 months. Executives at the biggest Covid vaccine makers including Pfizer and Moderna said they believe most people who wanted to get vaccinated against Covid have already done so - more than five billion people worldwide. In the coming year, most Covid vaccinations will be booster shots, or first inoculations for children, which are still gaining regulatory approvals around the world, they said. Pfizer, which makes its shot with Germany's BioNTech and Moderna still see a major role for themselves in the vaccine market even as overall demand declines. Upstart US vaccine maker Novavax and Germany's CureVac, which is working with GlaxoSmithKline, are developing vaccines they hope to target at the booster market. The roles of AstraZeneca and Johnson & Johnson, whose shots have been less popular or effective, are expected to decline in this market.

British drugmaker AstraZeneca says it's confident that its new version of COVID-19 antibody treatment could protect immunocompromised patients against all known virus variants. Laboratory studies show the antibody, called AZD3152, neutralises all known variants of COVID-19 and AstraZeneca has support from regulators to make the treatment available by the end of this year, the company's vaccines head Iskra Reic said on Tuesday (April 18). AstraZeneca plans, pending more positive data and regulatory approval, to make the antibody available by the end of 2023. These types of therapies are most needed for people with compromised immune systems, either because of underlying conditions or because they are undergoing immune suppressing treatments. They account for nearly 2% of the global population. AstraZeneca's AZD3152, it new COVID-19 antibody, was acquired through a $157 million deal last year with British biotech start-up RQ Bio. The British drugmaker will likely make future investments like its current partnerships with RQ Bio but did not have any deals to announce, said Reic, a long-time AstraZeneca executive who has led the company's vaccines and immune therapies unit since it was formed in late 2021, during the pandemic.

American global healthcare company, Viatris, has launched a new rapid self-test for qualitative detection of antibodies developed after Covid-19 vaccinations. The firm is going to market the Covid-19 Neutralising IgG Serological self-test, manufactured by PRIMA Lab SA, in the UK market, which would check presence of neutralising antibodies after vaccination. The presence of antibodies indicates that a person has had an immune response to the Covid-19 vaccine, and not that protective immunity has been acquired. The self-test that can be performed easily at home with a small blood sample, delivers results in just 10 minutes and has a recommended retail price of sub £20. After two doses of the Covid-19 vaccine, the self-test has shown a seroconversion rate of 98.3 per cent for the Pfizer vaccine, 98.5 per cent for the AstraZeneca vaccine and 95.2 per cent for the Moderna vaccine. It recommended that the test be performed at least 14 days after completing the vaccination cycle.

Covid-vaccine maker AstraZeneca said Friday that profits fell sharply in the first half on ballooning costs linked to its takeover of US biotech firm Alexion. The pharmaceutical group added that sales of its Covid-19 vaccine Vaxzevria slumped 49 percent in the second quarter. Net profit slumped 64 per cent to $746 million compared with the first six months of last year, AstraZeneca said in a statement. Operating expenses jumped 33 percent, "reflecting the addition of Alexion, and continued investment in new launches and the pipeline" of drugs, the group said. That offset a 48-percent jump in revenue to more than $22 billion. Revenue rose strongly thanks to sales of Alexion medicines. The group said annual revenue from Covid-19 medicines is anticipated to be broadly flat compared with 2021.

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.

Covid-19 vaccines made by Pfizer and Moderna that use mRNA technology provide the biggest boost to antibody levels when given 10-12 weeks after the second dose, a new study has found. The "COV-Boost" study was cited by UK officials when they announced that Pfizer and Moderna were preferred for use in the country's booster campaign, but the data has only been made publicly available now. The study found that six out of the seven boosters examined enhanced immunity after initial vaccination with Pfizer-BioNTech's vaccine, while all seven increased immunity when given after two doses of AstraZeneca's vaccine. "A third dose will be effective for many of the vaccines we've tested and in many different combinations," Professor Saul Faust, an immunologist at the University of Southampton and the trial's lead, told the media.

An alliance of companies has pledged to ensure equitable access to vaccines and treatments for pandemics, as the friction around intellectual property rights for Covid-19 interventions between the pharmaceutical industry and developing nations endures. At the heart of the plan is a commitment to set aside part of the production of vaccines and treatments upfront for vulnerable populations in low-income countries when the next pandemic arises, given how fragmented access to Covid tools has left many populations unprotected. In order to do better next time - and without knowing which companies will develop the first drugs and vaccines for the next pandemic - having the industry collectively make this commitment is potentially transformative, said Thomas Cueni, head of the International Federation of Pharmaceutical Manufacturers & Associations (IFPMA). The pledge, called the Berlin Declaration, was made on July 19 by members of the global pharmaceutical industry group that include many of the companies involved in developing Covid interventions, such as AstraZeneca, GSK, Moderna, Pfizer and Merck. The declaration is not legally binding. However, if a company that signed on reneges on its vow, it would face grave consequences in the court of public opinion, said Cueni.

Health authorities in India have said that Biological E's Covid-19 vaccine Corbevax can be administered as a booster dose in people who have taken the country's other two main shots, Covaxin and AstraZeneca's Covishield, from Friday (Aug 12). Corbevax will be available to over 18s as precautionary booster six months after a second dose, the health ministry said in an August 8 letter to state authorities. Covishield is produced for the Indian market by the Serum Institute of India under licence from AstraZeneca, while Bharat Biotech makes Covaxin. India has so far administered more than 2 billion Covid vaccine shots, including 113 million boosters, all of which have so far been of the same vaccine as the recipient's first two doses. The government says about 89 per cent of Indians above the age of 12 have had two doses.

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.
