How much protection will the H1N1 flu shot provide for next year’s flu season?
Research is currently being conducted to determine how long immunity will last following use of the adjuvanted vaccine. Real-time vaccine effectiveness will be evaluated using the same surveillance methodologies as for seasonal flu vaccine effectiveness. Since the H1N1 Flu Virus is only one of three flu viruses that may circulate next year, it will be important that people receive next season’s vaccine to ensure good protection next year.
