Filter by:The purpose of this study is to identify the following problems and questions with respect to the safety of Pneumococcal 7-Valent Conjugate Vaccine (Diphtheria CRM 197 Protein), Prevenar, during the post-marketing period in Korea, as required by Korea Food and Drug Administration (KFDA) regulations. 1. Adverse reactions (especially serious adverse reactions) 2. Incidences of adverse reactions under routine vaccine use 3. Factors that may affect the safety of the vaccine
Two( 2) or three (3) instead of four vaccinations before the age of 6 months with pneumococcal conjugate vaccine are presumed to protect children against invasive pneumococcal disease like meningitis, at least on the short term till 18-24 months of age. The current hypothesis in this study is 2 or 3 vaccinations will protect against IPD but will not alter pneumococcal nasopharyngeal carriage in infants, and consequently not change pneumococcal transmission and induce no herd-immunity. Furthermore, antibody development and memory may benefit from carriage of vaccine type S. pneumoniae
Pneumonia is the most common reason for admission of Fijian children to hospitals. The most common germ causing pneumonia is "streptococcus pneumoniae." It is a common cause of meningitis (infection around the brain and spinal cord), ear infections, and blood infections and it lives in the nose of humans. A vaccine has been developed that will help prevent these common diseases but prevents only about one quarter of pneumonia cases and it is expensive. This study explores new ways of giving this vaccine that are affordable, safe, and effective in countries such as Fiji. About 550 Fijian infants presenting at 6 weeks of age, for their first diptheria, tetanus, toxoid, pertussis vaccine immunization, to one of the participating Health Centers or Colonial War Memorial Hospital in urban Suva, Fiji will be enrolled. Children will remain in the study for 2 years. Study procedures include full vaccination against 7 types of pneumococcus, blood tests, and nasal swabs.
The purpose of this study is to learn whether or not giving a tetanus/diphtheria vaccination ("tetanus shot") before giving pneumococcal vaccine makes the pneumococcal vaccine more effective without causing too many side effects.
To test the hypothesis that immune responses to 23-valent pneumococcal polysaccharide vaccine (PPV-23) could be improved in Alaska Native elders by immune priming with 7-valent pneumococcal conjugate vaccine (PCV-7), we assessed post-vaccination immune responses among Natives aged 55 years and older who were randomized into three arms: (1) one dose of PPV-23 according to current state and ACIP recommendations; (2) one dose of PCV-7 followed two months later with a dose of PPV-23; and (3) one dose of PCV-7 followed six months later with a dose of PPV-23.
This prospective randomized evaluation of pneumococcal vaccine immunization of pregnant mothers, followed by pneumococcal conjugate immunization of their children is designed to assess the effects of these strategies on the immunogenicity and safety of both vaccines. We hypothesize that maternal followed by infant immunization will be safe and will provide higher levels of antibody from birth through 12 months of age.
The purpose of this study is to determine whether people who are HIV-positive respond better to a vaccine for pneumonia-related disease when they are immunized immediately, or when immunization is delayed until the immune system has improved to a certain level. The study will also compare the effectiveness of polysaccharide and heptavalent vaccines.
The purpose of this study is to evaluate the safety and immune response of a conjugated pneumococcal vaccine compared to a licensed 23-valent polysaccharide pneumococcal vaccine in elderly adults. Study participants will include 180 adults, 65 years of age or greater. Participants will be randomly assigned to 1 of 3 possible groups. Subjects will maintain a study diary to record side effects and oral temperatures for 7 days following each vaccination. Blood samples will be collected before and 1 month following each dose of vaccine or placebo. Participants will be involved in study related procedures for up to 268 days.
The purpose of this trial is to evaluate the safety, tolerability, and immunogenicity of an investigational pneumococcal vaccine in healthy adults.
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.
