To measure the efficacy of the vaccine, defined as the prevention of laboratory-confirmed influenza caused by viral types/subtypes that are antigenically similar to those contained in the respective annual vaccine formulations.
- To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, with respect to laboratory-confirmed influenza illness caused by any type or subtype of influenza virus.
- To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, in preventing culture-confirmed influenza illness caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations.
The occurrence of influenza-like illness (ILI) will be determined in elderly participants vaccinated with either Fluzone High Dose or Fluzone® vaccine.
The presence of influenza virus in the respiratory tract of vaccinated individuals with ILI will be confirmed by two methods.

The present formulations are being developed for further study in the elderly population in order to generate additional supporting data. Primary Objective: To demonstrate non-infe...
The study described here will immunize children with trivalent influenza vaccine (TIV) and determine whether this reduces influenza illness among the immunized children and their older fam...
This randomized, open-label, single-site study at Saint Louis University will enroll approximately 40 subjects who are healthy, 18 to 49 years old. Subjects will be randomized in a 1:1 fas...
A single center, randomized clinical trial is to be conducted in healthy adults (18-60 years) to evaluate the safety and immunogenicity and study the cell-mediated Immunity of Sinovac's H1...
This is a follow-up of a previous dose-ranging study aimed at investigating 2 doses of the trivalent inactivated split virion influenza vaccine when administered by intradermal route with ...
To compare immunogenicity, reactogenicity and acceptability of high- and standard-dose trivalent inactivated influenza vaccine (HDTIV, SDTIV) in 18-64 year olds.
Influenza is responsible for a significant disease burden annually, especially in older adults. This study reviews the relative vaccine efficacy or effectiveness (rVE) of high-dose inactivated trivale...
Prior influenza immunity influences homologous neutralizing antibody responses elicited by inactivated influenza vaccines (IIV), but neutralizing antibody responses to heterologous strains have not be...
The study examined the influence of sex and mouse strain on germinal center (GC) reaction and antibody responses to seasonal split trivalent influenza vaccine (TIV).
Currently, circulating viruses responsible for annual seasonal influenza epidemics belong to two influenza A subtypes, A(H1N1) and A(H3N2), and to two antigenically distinct type B lineages, B/Yamagat...
Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.
A suspension of formalin-inactivated poliovirus grown in monkey kidney cell tissue culture and used to prevent POLIOMYELITIS.
Vaccines used to prevent POLIOMYELITIS. They include inactivated (POLIOVIRUS VACCINE, INACTIVATED) and oral vaccines (POLIOVIRUS VACCINE, ORAL).
Antimony complex where the metal may exist in either the pentavalent or trivalent states. The pentavalent gluconate is used in leishmaniasis. The trivalent gluconate is most frequently used in schistosomiasis.
Vaccines or candidate vaccines used to prevent and treat RABIES. The inactivated virus vaccine is used for preexposure immunization to persons at high risk of exposure, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis.
A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one ...
