The data shows anywhere from a 25 to 50 percent decrease in mortality and hospitalization rates from heart-related events for vaccinated patients. One study found that heart-attack deaths rise in flu season and fall in the off-season like clockwork.
Unlike adult flu-related deaths, pediatric flu-related deaths are reportable in the United States. (See Pediatric Influenza.) For the 2019-2020 influenza season, 55,000 influenza-related hospitalizations had been reported as of early January 2020, and 2900 attributable deaths had been reported at that time, including 27 pediatric deaths.
