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.
An enzyme (protein) that's part of the human immunodeficiency virus reads the sequence of viral RNA nucleic acids (yellow in graphic) that have entered the host cell and transcribes the sequence into a complementary DNA sequence (shown in blue). That enzyme is called reverse transcriptase .Without reverse transcriptase, the viral genome couldn't become incorporated into the host cell, and couldn't reproduce. Reverse transcriptase sometimes makes mistakes reading the RNA sequence.The result is that not all viruses produced in a single infected cell are alike.ZT-like Drugs Inhibit Reverse Transcription. The first major class of drugs found useful in slowing HIV infections are collectively called reverse transcriptase inhibitors (shown in red). These include AZT, 3TC, d4T, ddc, and ddl that act by blocking the recoding of viral RNA into DNA.
