Vaccines Treatment Options in Virginia

The purpose of this study is to investigate the effectiveness, safety, and tolerability of an influenza vaccine. Influenza is a highly infectious disease that occurs throughout the world in the winter months. Infection with an influenza virus is a major public health threat as it has the ability to spread rapidly and affect large numbers of people. Up to 1359 healthy adults ages 18 to less than 65 years old will participate in this study for up to 24 days. Volunteers will receive an injection of either influenza vaccine with thimerosal, vaccine without thimerosal, or placebo with thimerosal. Volunteers will be asked to document information about any health changes for 21 days following vaccination. Volunteers will return to the clinic on days 5 and 21 after vaccination to share this information with study staff. On day 21, volunteers will have a physical examination. Blood samples will be taken prior to vaccination and at Day 21 post-vaccination. Read Less

The goal of this study is to determine whether the immune responses induced by Fluviral, the investigational vaccine, are comparable to those induced by Fluzone, which is an influenza vaccine currently licensed in the U.S. The study focuses on persons 50 years old and over. In addition, the study will compare the rate of reactions to the two vaccines, and the general health of persons who receive them over the 42 days after immunization. Read Less
