简要总结
Influenza viruses are significant causes of human illness and death in developed and developing countries. This study will measure the ability of influenza vaccine given to children in India to protect both the children and unimmunized persons around them from influenza. It will also determine whether the best time to immunize in a country like India that has both summer and winter outbreaks of influenza is in the fall, as is done now, or whether immunization should be in the spring to protect against influenza infections in the summer.
详细描述
Although influenza vaccines are used routinely in the United States, including in young children, influenza vaccines have not seen widespread use in India. This is likely contributed to by the lack of information from India about disease burden due to influenza and because influenza vaccines have not been tested for efficacy in India. In addition, because young children are thought to be important in the spread of influenza in families, it is possible immunization of children against influenza will reduce influenza infections among older children and adults in the home. The study described here is an extension of an earlier study (ClinicalTrials.gov NCT00934245) that tested the use of immunization against influenza in the fall. The current study will administer influenza vaccine in the spring prior to the summer monsoon rains that are associated with peaks of influenza activity in parts of India. Reduction of influenza infections among the influenza immunized children and their household members will be compared to the children and household members in the control vaccine group.
