With fall in full swing, the flu season is right around the corner. It is time to reduce the chance of becoming infected with influenza.
Influenza remains a worldwide problem because of frequent changes in the virus.
New vaccines are prepared in anticipation of the virus strains expected to prevail during the winter flu season. Outbreaks of influenza reach a peak between late December and early March. The optimal time for vaccination for influenza is October through early December. Protection from the vaccine begins 1-2 weeks after the injection and can last 6 months to 1 year. The influenza virus is spread in the air by an infected person to others.
