Since the flu virus changes each year it is necessary to be vaccinated each year. You could have some symptoms after the flu vaccine, such as fever or site soreness, but these symptoms will be mild. Since the vaccine does not take effect for several weeks, you should receive it in the early fall before the influenza season begins. Yes, by taking steps such as vaccinating adults that have contact with children. Also, all children with risk conditions should be vaccinated and parents should check with their child's doctor as to the advisability of giving the influenza vaccine.
Hand washing is always a great line of defense against any and all viruses.
The protocols used by preschools for cleaning shared equipment and toys are another good defensive strategy. The health care policies used in schools aid in decreasing the incidents of illness. If we work together we may be able to reduce the occurrence of flu in our schools this year. Your input and comments on how to enhance our effort are welcomed and appreciated.
