During the discussion, Anderson encouraged the audience to get a flu shot, suggesting that it may help with the coronavirus. Is this true?

Greg. G Wolff, an Epidemiologist with the Armed Forces Health Surveillance Branch recently published a study in the Journal Vaccine titled,  Influenza vaccination and respiratory virus interference among Department of Defense personnel during the 2017–2018 influenza season. The study examined virus interference in a Department of Defense population, this refers to the increased risk of other respiratory viruses as a result of, in this case, the influenza vaccine. The study found that virus interference varied among vaccinated individuals for individual respiratory viruses, and found that for coronavirus in particular, in this study, those who had been vaccinated with the flu vaccine had a 36 percent higher risk  of contracting it

The study compared the vaccination status of more than two thousand people with non-influenza respiratory viruses to more than three thousand people with pan-negative results. The vaccination status of more than three thousand cases of influenza were compared to three different control groups, and appropriate adjustments were made.
