a.
Recorded vaccinations in the Vaccine Information System only (see Table 4 for the percentage of patients included in the Vaccine Information System). The percentages reported over all participants included in the Vaccine Information System and with any vaccination ever recorded in the Vaccine Information System.
b.
Encompassing epidemiological weeks 52 to 12, with influenza related admissions identified in> = 65 years subjects. This was the age group targeted to receive this type of vaccine.
c.
Encompassing epidemiological weeks 4 to 10, with influenza related admissions identified in <65 years old subjects. This was the age group targeted to receive this type of vaccine.
