Immunizations are an important public health concern in order to help control the spread of diseases. Influenza is a particularly important seasonal vaccine, as it is updated every year and recommended that all people receive the vaccination. Unfortunately, not everyone receives the vaccine, which can make others more susceptible to contracting the disease andspreading it to others. Using data from the Center for Disease Control’s (CDC) National Immunization Survey (NIS), the number of child and teenage influenza vaccinations were compared before and after the H1N1 (Swine Flu) pandemic of 2009. It was hypothesized that the H1N1 outbreak would lead to an increased rate of vaccinations in both children and teenagers. The data was grouped by geographic region and socioeconomic status. The comparative results show that there was not an increased number of childhoodor teenage vaccinations relative to the total amount of influenza vaccinations that were administered, indicating that the H1N1 pandemic did not cause a greater number of influenza vaccinations in the following years.
