As you are well aware, the flu vaccine becomes increasingly important to avoid the outbreak dilemma, especially for those clients with an immune system that is already comprised in some way. The vaccine has been shown to significantly reduce the risk of getting the flu, or of its causing death in elderly or severely ill patients. There is still widespread discussion about whether the vaccine should be a required vaccination, but it is currently readily available in clinics, health centers, and offices around the world.
Like any other vaccination, there are a few side effects of which medical practitioners should be aware. In general, these side effects are mild, and appear 24 to 48 hours after the injection. These include fever, achy body, and redness or swelling around the area where the shot was administered. If the flu vaccine is taken nasally, it can also cause runny nose, sore throat, headache, wheezing, or vomiting, especially in children. Only occasionally has the vaccine caused a severe allergic response.
