Flu Vaccine Topic Guide
Flu Vaccine: Flu vaccines may be composed of weakened live flu viruses or killed viruses that protect a person from developing influenza once administered. Reactions to the seasonal flu and H1N1 flu nasal-spray vaccines and shots include headache, nasal congestion, low-grade fever, sore throat, and muscle cramps.
Swine Flu Prior to 2009, swine flu was a form of influenza that predominately affected swine. The virus was not easily transmitted to humans. However, the swine flu virus has mutated, allowing for person-to-person transmission. Swine flu symptoms include fever, sore throat, and cough. Infected individuals may also experience fatigue, headache, chills, or body aches. Lab testing is needed to confirm a diagnosis of swine flu. Treatment may involve oseltamivir or zanimivir.
