The timeline below shows the total seconds of daily airtime across BBC News, CNN, MSNBC and Fox News in which the onscreen text (chyrons, "scroll", etc) mentioned vaccines since the start of this year (a 7-day rolling average is used to smooth the data). Unsurprisingly, mentions have soared since Nov. 9 when the success of Pfizer's vaccine was announced. Yet BBC has turned sharply away from the vaccine since earlier this month while the other three channels have turned away over the past week. This is mirrored in spoken word mentions as well.
