2016 Influenza Immunization Health Indicator Report

Purpose of the Health Indicator Report

The purpose of this health indicator report is to provide information about the percentage of Halton adults aged 18 and over who received the influenza vaccine for the past influenza season.

Background

Influenza (“the flu”) is a respiratory illness caused by the influenza virus. In Ontario, the flu season typically occurs each year from November to April. Common symptoms of the flu include fatigue, body aches, headache, and sore throat. Older adults, pregnant women, and people with chronic diseases may be at risk for more severe complications from the flu. The best way to be protected from the flu is to receive the influenza vaccine. The flu virus can change from year to year, so it is important to be vaccinated every year.

This health indicator report uses data from the Rapid Risk Factor Surveillance System (RRFSS).
