Moderna gave its mRNA-based seasonal flu vaccine to the first set of volunteers in a clinical trial, the pharmaceutical company announced today. The start of the trial marks the next stage of the company’s work on this type of vaccine technology after the overwhelming success of its COVID-19 vaccine, which was built using the same strategy. Before the COVID-19 pandemic, mRNA vaccines were still largely experimental, even as they were heralded as the future of vaccine development. People who get an mRNA vaccine are injected with tiny snippets of genetic material from the target virus. Their cells use that genetic information to build bits of the virus, which the body’s immune system learns to fight against. The high efficacy of the mRNA COVID-19 vaccines made by Moderna and Pfizer / BioNTec...
Israeli Prime Minister Benjamin Netanyahu and Bahrain’s Crown Prince Sheikh Salman bin Hamad Al Khalifa on Thursday discussed Iran and the possible involvement of the Gulf state in establishing a vaccine plant in Israel, the two countries said. Bahrain and the United Arab Emirates formalised ties with Israel on Sept. 15 in part over shared concerns about Iran, in a deal forged by former U.S. President Donald Trump. Trump withdrew from a 2015 nuclear deal between Tehran and world powers, a move praised by Israel which has objected to the accord. His successor, President Joe Biden, wants to rejoin the deal. But in the week since Washington offered to talk with Tehran about reviving the nuclear deal, Iran has curbed U.N. monitoring and threatened to boost its uranium enrichment. Tehran denies...
More than a million people have received their first dose of a Covid-19 vaccine in the United States, Centers for Disease Control and Prevention (CDC) director Robert Redfield said Wednesday. “The United States achieved an early but important milestone today — jurisdictions have now reported that more than one million people have received their first dose of Covid-19 vaccine since administration began 10 days ago,” said Redfield. In a call with reporters, Moncef Slaoui, chief advisor of the government’s Operation Warp Speed, said that the objective of immunizing 20 million people this month was “unlikely to be met.” But he said the US was still aiming for 100 million people immunized by the end of the first quarter of 2021, and another 100 million by the second quarter. Three million doses...
A new strain of the novel coronavirus disease (COVID-19) that grounded the global economy for all of 2020, has been identified in Nigeria. The mutant variant was first identified in the United Kingdom (UK) and has caused several countries to ban flights from the UK. It has also led the UK government to announce a slew of fresh restrictions and lockdowns. Newsmen report that this new strain has been identified in Nigeria by scientists at the Africa Centre of Excellence for Genomics of Infectious Diseases (ACEGID), at the Redeemers University in Ede, Osun State. In a publication in Virological, a website for the global Genomics community, the scientists say they found the same variant “lineage B.1.1.7” in Osun State, Southwest Nigeria since August 3, 2020, when the first sample was collected...
A coronavirus vaccine developed by Britain’s University of Oxford and the pharmaceutical firm AstraZeneca has shown successful results in early trials. If it is approved by regulators, the vaccine appears suitable for a fast rollout around the globe. Early analysis of trials involving 20,000 volunteers in Britain and Brazil show the vaccine is at least 62% effective after two doses. In volunteers given a different dosing regimen — a half dose, followed by a full dose — that figure rose to 90%. The average efficacy of the two dosing methods is 70%. None of those given the vaccine developed severe COVID-19 illness. Andrew Pollard, director of the Oxford Vaccine Group, said the recent successful trials of three different vaccines by Oxford-AstraZeneca, Pfizer-BioNTech and Moderna, represent a...
