We are fortunate there is a safe and effective vaccine to protect us from the flu. The Immune Deficiency Foundation (IDF) represents some 250,000 people in the U.S. with primary immunodeficiency diseases (PI), rare but serious conditions in which the immune system is absent or functions improperly. Our population, along with the elderly, infants, those on chemotherapy and those for whom vaccines don't work, are all at a higher risk of severe illness and even death if they get the flu.
It is easy and critical to protect yourself by getting vaccinated and at the same time protect your more vulnerable neighbors who are unable to directly benefit from the vaccine because their immune systems aren’t working properly.
If all appropriate people in a community get a flu shot, we can create a "protective cocoon" of immunized persons surrounding more vulnerable individuals so that they have less chance of being exposed.
That herd immunity where nearly everyone in the community is vaccinated is the best way to protect those whose immune systems are fragile. Getting a flu shot is an act of kindness. Please get a flu shot and protect not only yourself but also those in your community whose immune systems are at risk.
