People are being urged to get vaccinated in advance of this year’s potentially more aggressive flu strain. Medical Health Officer Dr. Charmaine Enns says the sooner people get vaccinated, the better. Enns says every year the vaccine components change on what strains of influenza it protects against, based on a global surveillance to try to make the vaccine most protective for what will most likely going be circulating. Vaccinations are free for patients at risk of complications. Island Health will begin offering public flu shots on October 31st.
