Official title

A Randomized, Double-Blind Trial, Comparing the Safety in Mothers and Their Infants and Immunogenicity in Mothers of Live Attenuated Influenza Vaccine (LAIV) to Inactivated Trivalent Influenza Vaccine (TIV) When Administered to Breast Feeding Women

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to learn more about the safety of 2 licensed flu vaccines, nasal spray and flu vaccine shot, in mothers and their infants, when given to women who are breastfeeding and to compare the immune response (body's defense against foreign substances) of breastfeeding mothers, who receive intranasal flu vaccine, with breastfeeding mothers receiving the flu vaccine shot. Healthy women (240 volunteers, 28-120 days post delivery) who plan to breastfeed through 28 days post vaccination and who have not received influenza vaccine for the influenza season for which they are being enrolled, will be assigned by chance to 1 of the 2 vaccines in the following manner: flu vaccine nasal spray and a placebo (inactive substance) shot or a flu vaccine shot and a placebo nasal spray. Study procedures include: nasal swabs, blood samples, and completion of memory aids. Participants will be involved in this United States based study for about 6 months.
