Vaccine trials spark tensionsAs the US speeds up its search for a covid-19 vaccine, tensions have erupted between scientists and Moderna, a leading developer, Reuters reports.
The US government has given Moderna, a firm that has never produced an approved vaccine, nearly half a billion dollars. Scientists say Moderna has delayed trial protocols and resisted advice on how to run the study.
On Tuesday, the US gave a $1.6 billion contract to biotech firm Novavax for a covid-19 vaccine. The New York Times describes Novavax as “a company that has never brought a product to market".
In India, scientists have warned that Bharat Biotech may be rushing critical phases of vaccine trials as it aims to meet a 15 August deadline.
