Key Concept

Key Evidence: In a retrospective cohort study among healthcare workers (HCWs) of an Italian academic healthcare trust during the 2017–2018 influenza season, non-vaccinated HCWs lost 2.47/100 person-days of work compared to 1.92/100 person-days of work among vaccinated HCWs (p < 0.001). This adds further evidence that absenteeism among HCWs is negatively correlated with influenza vaccination.

A school-located influenza vaccination program implemented in 95 preschools and elementary schools in California was associated with increased influenza vaccination coverage, decreased school absences due to illness, and lower influenza transmission across the community. The 11% increase in flu vaccination in children enrolled in target schools was associated with fewer flu hospitalizations in the community, including 160 fewer influenza hospitalizations per 100,000 among people aged 65 and older.

Key Evidence: Children hospitalized with rotavirus in Norway were absent from daycare for 6.3 days, on average, and 73% of their parents missed work — for a mean of almost 6 days. These data, which can be used in economic evaluations of rotavirus vaccination, show that work absenteeism resulting from having a child hospitalized with rotavirus poses a considerable economic burden on society.

Healthcare workers who received an influenza vaccine missed fewer days of work compared to non-vaccinated peers (1.74 vs 2.71 days/person). The study took place at a large Italian hospital that employed approximately 5,300 healthcare workers. The researchers examined a severe influenza season (2017/2018) as well as three moderate flu seasons (2010-2013).
