Brazil’s health regulator has suspended a clinical trial for China’s Sinovac coronavirus vaccine citing a severe adverse event, surprising the trial organisers who countered there had been a death but it was unrelated to the vaccine. More...
Coronavirus mutation could hamper vaccine development
New strain first emerged in Scotland and has now spread to 12 other countries but is not making the disease more severe or transmissible
A team of scientists from institutions around the world, including the universities of Glasgow, Edinburgh and Liverpool, has conducted an indepth study of an emerging strain of the virus that has been shown in clinical trials to evade monoclonal antibodies – the first tailored treatment for Covid-19.
