FLUVIRINÂ® (Influenza Virus Vaccine) is an inactivated subunit influenza virus vaccine indicated for active immunization of persons aged 4 years and older against influenza disease caused by influenza virus subtypes A and B included in the vaccine.1.
All viruses contain either RNA or DNA surrounded by a protective protein shell called a capsid. The genetic material in a virus may take one of four forms: a double strand of DNA, a single strand of DNA, a double strand of RNA, or a single strand of RNA. The size of the genetic material of viruses is often quite small.ype C viruses are the least common type of influenza virus and cause irregular and milder infections. An important characteristic of all three kinds of influenza viruses is that they frequently mutate. Because they contain only a small amount of genetic material, flu viruses mutate frequently.
