(Bloomberg) Vaccine makers, including two of the biggest in the world, suffered setbacks in the push to get more Covid-19 shots across the line, tempering a run of positive news.
Sanofi and GlaxoSmithKline Plc delayed advanced trials of their experimental Covid-19 shot after it failed to produce a strong enough response in older people, pushing its potential availability to the end of next year. In another blow, trials of a vaccine being developed by CSL Ltd. and the University of Queensland in Australia ran into difficulties.
