THREAD: There's risk a second wave of #COVID19 in Fall 2020 will coincide with flu season; and surging covid infections will confound ability to ramp testing, make full use of syndromic surveillance, preserve hospital capacity. What can we do to prepare? https://www.washingtonpost.com/health/2020/04/21/coronavirus-secondwave-cdcdirector/

A key step we can take is to increase flu vaccination rates. Covid adds a compelling reason for people to want to get vaccinated. The risk of co-infection with flu can accelerate death and disease with covid. There's much room to drive up vaccination rates among U.S. adults. 2/3

One key consideration for FDA, CDC: Make sure we have enough flu vaccine. Typically manufacturers will make about 140-160 million doses for U.S. market. We need to anticipate demand will be higher this year, and vaccination campaigns more intense -- and seek enough supply.
