H1N1 refers to a specific influenza virus. All influenza viruses are categorized based upon the hemagglutinins and neuraminidase receptors. H1N1 is a significant concern for public health because it was a new a strain that was not previously seen in humans. Therefore, large amounts of individuals were susceptible to it. Previous versions of flus are seen repeatedly, which means that people have some natural immunity to them. Since no one had any antibodies to this strain, there was concern of a pandemic. The 1918-19 Spanish Influenza Pandemic is believed to have been a similar issue, in which no one had any native immunity to the disease.
Unfortunately, many people argue against vaccinating individuals because of false scientific reports that vaccinations are harmful. While these false reports concerned MMR vaccination and children, many people now assume that all vaccinations are harmful. Furthermore, in 1976, there was a small outbreak of cases of Guillian-Barre syndrome following vaccination for the influenza virus. This was a rare complication caused by an immune response. The risks of dying from the flu are greater than the risks of this condition. This is particularly true for younger and older individuals, or those with health conditions.

Vaccination for influenza absolutely alleviates concerns with regards to resources. When massive individuals have the flu, they often call 911 and utilize EMS to go to an emergency department. These resources are then not available for patients who are having heart attacks. Furthermore, treatment for the flu, such as IV fluids, medication for vomiting and antivirals are much more expensive than a flu shot, which could prevent the need for care. One must also consider the lost time and lost productivity due to individuals who have the flu. While one does not want a sick person going to work and infecting others, the person still leaves his or her work for others to do.
