Vaccines Treatment Options in Connecticut

INVESTED will test the hypothesis that high dose trivalent influenza vaccine will reduce cardiopulmonary events to a greater extent than standard dose quadrivalent influenza vaccine in high-risk cardiovascular patients with a recent history of myocardial infarction or heart failure. The trial will enroll 9300 participants over one Vanguard (pilot) season and three additional influenza seasons. The primary endpoint will be a composite of all-cause mortality or cardiopulmonary hospitalization. Read Less

This is a prospective, single-site, randomized, then open-label study designed to develop a detailed transcriptional and epigenetic profile of the immune response to pneumococcal vaccination with conjugated and non-conjugated polysaccharide vaccines in the senescent immune system of older adults. In this study, 40 healthy adults ages 60 and older that have never received pneumococcal vaccination, will be randomized in a 1:1 ratio to receive Prevnar-13 (Pfizer), a conjugated 13-valent vaccine or Pneumovax 23 (Merck), a non-conjugated 23-valent vaccine. Following randomized assignment of vaccine, the study will be open-label. Six (6) study visits will occur over about 70 days, with an optional 7th visit for participants to receive a second vaccination with the other pneumococcal vaccine one to two years after randomization. Participants will provide blood samples for transcriptional, epigenetic and biological analyses pre- and post-vaccination. Read Less

The purpose of this study is to determine immune system function following vaccination in HIV-infected children currently taking anti-HIV drugs. To test the effectiveness of prior vaccination, patients in this study will receive booster shots of one of two pneumococcal vaccines, a hepatitis B vaccine, and a measles vaccine. Read Less

The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection. Read Less

The purpose of this study is to compare two flu vaccines to determine their safety and ability to stimulate an immune response in HIV infected children and adolescents. This study will also determine how often and how long people who receive a vaccine are able to spread flu vaccine virus to other people. Read Less

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' trivalent MMR (Priorix), comparing it to Merck's MMR vaccine (M-M-R II), which is approved for use in the US in healthy children 12 to 15 months of age. Read Less

The purposes of the clinical trial are to determine whether the SA4Ag vaccine can prevent postoperative Staphylococcus aureus infections in patients who are undergoing elective spinal fusion surgery, and to evaluate the safety of SA4Ag in patients who are undergoing elective spinal surgery.

With aging the immune system gets weaker. This makes older adults more susceptible to influenza (flu). Vaccinations help to prevent infection from the flu virus, however the immune system of older adults do not respond as well to vaccines compared to young adults and thus, aren't as well protected from the complications from the flu. This research is being done to determine if Metformin, an FDA-approved diabetes medication, is effective at enhancing immune responses to flu vaccine in older men and women. Participants will be randomly assigned to either metformin or placebo treatment for a total of 22 weeks. Participants will be vaccinated with high-dose flu vaccine after 12 weeks of treatment. Immune responses will be evaluated throughout the study at 6 time points. Read Less

Main goal of this study is to compare the occurrence of serious adverse events (SAEs) between the herpes simplex (gD2-AS04) vaccine group and the Saline control group throughout the study period (up to month 12). The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. Read Less

This study is evaluating the safety and immunogenicity of GSK Biologicals' Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine, each administered at 2, 4, and 6 months of age, and compared to licensed meningococcal serogroups A, C, Y, and W-135 polysaccharide vaccine administered at 3 to 5 years of age. The safety and immunogenicity of a booster dose of Hib-MenCY-TT vaccine will be compared to a booster dose of licensed Hib conjugate vaccine, each administered at 12 to 15 months of age. The group primed with the Hib conjugate vaccine will re-randomized at 12-15 months of age to receive a booster dose of Hib-MenCY-TT or a booster dose of the Hib conjugate vaccine. Read Less

This study will further evaluate the ACAM-CDIFF™ vaccine in a population of middle-aged to elderly individuals at risk of exposure to Clostridium difficile because of impending hospitalization or residence in a care facility. Primary Objectives: * To describe the safety profile of subjects in each of the study groups. * To describe the immune responses elicited by toxoid A and toxoid B of subjects in each of the study groups. Observational Objective: * To describe the occurrence of first-time Clostridium difficile infection (CDI) episodes. Read Less

The aim of the study is to assess the safety and immunogenicity of two formulations of the high-dose quadrivalent influenza vaccine compared to the licensed high-dose trivalent influenza vaccine control in healthy elderly subjects aged 65 years of age and above. Primary objectives: * To describe the safety profile of all subjects in each study group. * To demonstrate that the high-dose quadrivalent influenza vaccine induces an immune response (as assessed by HAI geometric mean titers (GMTs) that is non-inferior to responses induced by the licensed high-dose trivalent influenza vaccine for the 3 common virus strains at 28 days post-vaccination. Secondary objectives: * To describe post-vaccination immunogenicity for the 4 virus strains (as assessed by seroconversion and seroprotection) for subjects who receive the high-dose quadrivalent influenza vaccine and the licensed high-dose trivalent influenza vaccine. * To describe post-vaccination immunogenicity for the 4 virus strains (as assessed by GMTs, seroconversion, and seroprotection) for subjects who receive the high-dose quadrivalent influenza vaccine and the investigational high-dose trivalent influenza vaccine.
