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...
The European Union has struck a deal to initially pay less for Pfizer’s COVID-19 vaccine candidate than the United States, an EU official told Reuters News Agency as the bloc announced on Wednesday it had secured an agreement for up to 300 million doses. The experimental drug, developed in conjunction with Germany’s BioNTech, is the frontrunner in a global race to produce a vaccine, with interim data released on Monday showing it was more than 90 percent effective at protecting people from COVID-19 in a large-scale clinical trial. Under the EU deal, 27 European countries could buy 200 million doses, and have an option to buy another 100 million. The bloc will pay less than $19.50 per jab, a senior EU official involved in talks with vaccine makers told Reuters, adding that partly reflected ...
