Title: A Phase I Study of The Safety, Reactogenicity, Acceptability and Immunogenicity of Inactivated Influenza Vaccine Delivered either by Microneedle Patch or by Hypodermic Needle. This is a single center, partially blinded, randomized phase I study in which healthy adult subjects (ages 18-49) will receive either inactivated influenza vaccine (IIV) (either by microneedle patch or hypodermic needle) or placebo (by microneedle patch). This study is designed to investigate the safety, reactogenicity, acceptability and immunogenicity of an inactivated influenza vaccine delivered by microneedle patch.

Influenza is an acute respiratory disease caused by influenza viruses. There are three types of the virus including A, B and C. Both type A and type B viruses can cause acute febrile respiratory tract infection, characterized by sudden fever, headache, muscle pain, cough, sore throat, nasal congestion and general malaise. Influenza can periodically cause worldwide pandemic. For nearly a century, the influenza virus had occurred four large variation, causing three world pandemic. Studies have shown that since 1957, most of those new variants of influenza virus started in China, which is recognized by the world to have high incidence of influenza. At present, trivalent influenza vaccines are widely used in China. They only contain two kinds of type A virus antigens and one type B virus antigen. But since 2000, two kinds of type B strains (Victoria and Yamagata) have caused an alternating cycle in different seasons. Gradually, evolved from the original single lineage of influenza B virus B/Yamagata, two distinct antigenic lineages-B/Victoria and B/Yamagata have alternately dominated or caused a mix of popular lineage. These two lineages have little or nearly no cross-protection. Therefore, trivalent influenza vaccines may not cover the popular strains of influenza B virus, whereas quadrivalent influenza vaccines will help to simultaneously prevent two kinds of type A viruses and two kinds of type B virus.

This is a multi-center, randomized, double-blind, active comparator controlled study in which up to 450 healthy adults age 18-64 years will be administered either one of two dose levels of VAX2012Q or a licensed quadrivalent influenza vaccine. The subjects will be randomized at a 1:1:1 ratio.

The purpose of this study is to evaluate the safety and immunogenicity of GSK Biologicals' Quadrivalent Split Virion Influenza Vaccine Fluarix Tetra (2015 Southern hemisphere) in adults (18 to 60 years of age) and in the elderly (over 60 years of age).

April 2015 -
This is an open label single arm observational study of longitudinal immunologic responses to influenza vaccine in healthy adult subjects. This study will enroll males and non-pregnant females, 18-49 years old. The subjects will be screened at enrollment with a history and physical exam and laboratory testing to ensure they are healthy enough to participate. Qualifying subjects will be vaccinated with an FDA approved seasonal inactivated influenza vaccine (IIV) according to the package insert. Approximately 450 ml of blood will be collected for the research assays during the course of the study. Specifically, 16 ml will be collected for screening; 48ml will be collected at enrollment; 96ml will be collected at visit days 7 and 14; and 64 ml will be collected at 28, 90, and 180 days post vaccination. The study will enroll 10 healthy volunteers per vaccination season in years 1 and 3 through 6 of this study, for a total enrollment of 50 subjects.

April 2015 - October 2015
The purpose of the study is to better understand how the use of antibiotics changes micro-organisms in the intestines. The change to micro-organisms in the intestines may change the body's vaccine immune response and alter the effectiveness of the IIV (seasonal flu) vaccine. In particular, the investigators will be looking at certain markers in blood after vaccination with IIV (seasonal flu vaccine) with or without the use of antibiotics before vaccination. There will be two randomized groups. Group A will start taking antibiotic by mouth 3 days prior to vaccination and continue taking antibiotics the day of vaccination and one day after vaccination for a total of 5 days. Group B will only receive the IIV (seasonal flu vaccine) and will not take any antibiotics. The investigators hope to enroll 22 subjects at Emory.

Prospective cohort study to evaluate safety and immunogenicity of the fragmented, inactivated trivalent Influenza vaccine produced at Butantan Institute in healthy adults and elderly. The study will include a total of 120 participants: 60 participants aged 18 to 59 years in the healthy adults group, and 60 participants aged older than 60 years in the elderly group.This study will evaluate the safety of one dose of the fragmented, inactivated trivalent Influenza vaccine in the first 3 days after vaccination, as well as its immunogenicity 21 days after vaccination.

March 2015 - March 2015
Influenza (flu) viruses change continuously, therefore also the parts of viruses used in influenza vaccines can vary from year to year. The current study is a phase IIIa clinical trial with a commercially available vaccine (Influvac®) supplied in pre filled syringes. The objective of this study is to investigate the immunogenicity and safety and tolerability of the changed influenza vaccine virus composition in two groups of subjects in good health: subjects aged >= 18 and <= 60 years and subjects >= 61 years of age (elderly).
