You might want to consider adding additional protection measures (like a respirator), as the effectiveness of some vaccines can be moderate to non-existent. The effectiveness of the flu vaccine in years when its well-matched to the circulating strains is between 40% and 60%, and when the vaccine is not well-matched, it’s protection against illness plummets, although it may still offer some protection against complications such as pneumonia. Vaccines don’t exist for bad colds and the stomach flu.
