Benefits of Flu Vaccination in the United States during the 2018-2019 Flu Season
The 2018-2019 flu season was the longest in a decade. The A(H1N1)pdm09 viruses that circulated last season were mostly like the H1N1 flu vaccine component, while the A(H3N2) viruses were mostly drifted from the flu vaccine component. CDC estimates that vaccination helped prevent 4.4 million illnesses, 58,000 hospitalizations and 3,500 deaths, showing the importance of flu vaccine.2018–19 Influenza Illnesses, Medical Visits, Hospitalizations, and Deaths Averted by Vaccination
In addition to estimating the number of illnesses, medical visits, hospitalizations, and deaths due to influenza that occurred during the 2018–19 influenza season in the United States, CDC also estimates the burden of influenza that was averted by seasonal influenza vaccination. To do so, CDC uses the preliminary estimates of burden from the 2018–19 season in a model with vaccine coverage and vaccine effectiveness. Further description of the methods and the estimates of burden averted by influenza vaccination during the 2018–19 season are published and available at: https://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciz1244/5697292
