Branswell is from Canada and has family in Ottawa.[4][5] In 1978, Branswell received a B.A.inEnglish literature the St. Thomas UniversityinNew Brunswick, Canada. When asked how she wound up in journalism she replied: "I fell into journalism, I was not somebody who had worked at a high school newspaper or college newspaper or anything. I just didn’t know what to do after getting a Bachelor of Arts degree in English Literature. And somebody said, “What can you do?” And I said, “I think I can write.” And so, I started freelancing for the local paper in the small town I lived in at the time in Eastern Canada at $15 a story. And the rest is history, but with a lot of moves and a lot of different opportunities along the way."[1]
In 2011 Branswell was a Nieman Fellow at Harvard University.[11][12] Here she concentrated on Polio eradication, with a focus on how India is fighting the spread of poliovirus.[13][14] During an interview with the Nieman Foundation for Journalism, Branswell provided an overview of her experience on reporting during pandemics.[15] This report included advice on which stories to cover and which not cover, how to identify reliable sources and how to prepare for interviews with researchers.[15]The Canadian Press did not have a large budget and Branswell wrote most of her articles from her office or home.[15]
In 2015 Branswell left The Canadian Press to join Stat News,[16][3] a health news website which had launched that year. Branswell is a popular science communicator; she was often recommended as an important health journalist to follow on Twitter during the COVID-19 pandemic.[17][18][19] She was selected as a Harvard Medical School media fellow in 2019.[20]
Branswell led the Stat News reporting on the coronavirus pandemic. She first started sharing concerns about the emerging outbreak on December 31, 2019.[21][22] Branswell had read a ProMED-mail posting that described an unexplained pneumoniainWuhan, which concerned her because of its similarities to SARS.[21] Two days later, in early January 2020, Branswell tweeted, “Not liking the look of this”.[22] By January 4 Branswell had written her first article on SARS-CoV-2 for Stat News, predicting that it could be "a new coronavirus".[22]
Branswell used her Twitter feed to discuss recent developments as well as debunking misinformation. She remarked that, for the scientific community, this virus was different to other pandemics, because the rise of preprint serves meant that journalists and the public had access to data and research much faster than before.[21] She covered the development of a COVID-19 vaccine, interviewing the Head of Vaccine research at Sanofi, who estimated that it would take three years before the vaccine was widely available.[23] Sanofi have experience in the development of a SARS vaccination, as well as the ability to do large-scale manufacture, which Branswell believes is crucial to produce vaccinations for people all over the world. She questioned why Robert R. Redfield, director of the Centers for Disease Control, was so silent throughout the outbreak, whereas they provided regular briefings during the 2009 swine flu pandemic.[24][25]
