(ANSA-AFP) - FRANKFURT AM MAIN, DEC 1 - Pharma companies Pfizer and BioNTech on Tuesday filed for European approval for their coronavirus vaccine, following in the footsteps of competitor Moderna. US giant Pfizer and German newcomer BioNTech said their vaccine could be rolled out "in Europe before the end of 2020" if the European Medicines Agency grants so-called Conditional Marketing Authorisation. Moderna had applied on Monday for both US and EU approval of its vaccine, based on the same new mRNA technology and with a similar level of effectiveness at around 95 percent. (ANSA-AFP).
