Thunder Bay's Health Unit is reassuring the public after Canada suspended the distribution of flu vaccine made by the company Novartis. Spokesperson Darlene Binette says they are no longer using Fluad and Agriful because tiny clumps of virus particles can be found in some of the shots. Flu shot clinics are still open and the Health Unit is using other unaffected vaccines. Binette says they did offer Fluad and Agriflu earlier in the season but are putting that on hold for now and no unexpected adverse side effects from the shot have been reported.
