Filter by: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 50 subjects at Emory.
We evaluated the impact of viewing an educational video about influenza vaccination in pregnancy just prior to a routine prenatal visit on vaccination health beliefs and vaccination rate. We hypothesized that the video would positively impact both vaccination health beliefs and vaccination rate compared to a control video.
The purpose of this study is to examine the safety and tolerability after administration of trivalent and quadrivalent cell-based virosomal influenza vaccine in healthy adults.
The purpose of this pregnancy registry study is to detect and describe abnormal pregnancy outcomes in women intentionally or unintentionally vaccinated with any of GlaxoSmithKline (GSK) Biologicals' seasonal Inactivated Influenza Vaccines (sIIVs): Fluarix, FluLaval, Fluarix Quadrivalent and FluLaval Quadrivalent.
The purpose of this study is to investigate the responses to licensed trivalent, inactivated influenza vaccine (TIV) delivered by different routes: intramuscular (IM) and intradermal (ID) and to the live, attenuated influenza vaccine (LAIV) administered intranasally -- all given to generally healthy male and female adult volunteers.
To evaluate the safety of the post-licensed influenza virus vaccine made of Changchun Institute of Biological Products Co.,Ltd.
In this study we are trying to understand whether previous infection with a particular virus, namely cytomegalovirus (CMV), influences the ability of the immune system to respond to new infections or vaccinations with age.
This is an exploratory study using a strategy that has not been previously employed to investigate the effects of age and vaccine type on specific kinds of immune responses to licensed, seasonal 2009-2010 influenza vaccines in children and adults.
To monitor the safety of Shanghai Institute of Biological Products Company's influenza vaccine in subjects aged 3 years and older through Adverse Events Following Immunization Surveillance System of China. The hypothesis is that there is no significant difference in the occurrence of adverse events among influenza vaccines manufactured by SIBP and other companies.
In this study, the safety and immunogenicity of the current formulation of aTIV will be compared to aTIV-modified formulations in which the dosage of the MF59 adjuvant will be doubled or tripled and/or the dosage of the 3 influenza virus strains will be doubled, in independently-living elderly subjects ≥ 65 years of age.
