Side effects of Influenza vaccination

As we head into another influenza season we are trying to improve our hospital staff vaccination rates. The goal of vaccinating hospital staff is two fold. First to keep the staff from getting influenza themselves and second by keeping the staff from getting ill they do not become involuntary spreaders of disease to hospitalized patients. Thereby protecting the chronically ill patients at the hospital. The second reason described is often forgotten and overlooked. I cannot begin to count the number of times I have been told that they do not need a flu shot because they don’t sick from the “flu”.

Remember it is more about protecting patients, the weak and infirm who may not have the ability to tolerate a respiratory tract infection

After that discussion the next heard is concerns over vaccinating patients and how the vaccine can or will make them ill. Often cited is a concern that a post vaccination fever is not discern able from a post op fever. Archives of Internal Medicine published this study in 1996 by Nichol et al. The study, a randomized placebo controlled prospective trial looked at the number of symptoms including minor ones such as injection site pain and fever post vaccination compared to placebo. Their findings include that fever post vaccination is no more common than placebo.
