Interim trial results are encouraging as scientists welcome news
It is not yet the end of the pandemic, but the announcement by Pfizer/BioNTech that their vaccine has been 90% successful in the vital large-scale trials has got even the soberest of scientists excited.
These are interim results and the trial will continue into December to collect more data. The two companies – a tiny German biotech with the big idea and the giant pharma company Pfizer with the means to develop it – have not yet published their detailed data, so it is all on trust. And yet, nobody is suggesting the results have been over-egged. It looks as though the vaccine not only works, but works better than anyone hoped.
