This trial evaluates a new five-component vaccine (Tdcp) designed to protect against diphtheria, tetanus, and pertussis (whooping cough). It includes about 1,820 participants aged 7 and older, who receive either the experimental vaccine or a control vaccine. The study measures ho…

This study tests a hexavalent vaccine that protects against six diseases, including polio, but uses a lower dose of the inactivated polio vaccine (IPV). The goal is to see if this reduced-dose version works as well as the standard full-dose vaccine in infants. Around 1,500 health…

This completed study tracked over 10,000 people in Thailand who received the Boostagen® vaccine, which protects against tetanus, diphtheria, and whooping cough. Healthcare workers reported any side effects to see how safe the vaccine is in everyday use. The study also looked at p…

This completed study checked the safety of the Hexaxim vaccine in 713 infants aged 2 months and older in South Korea. Researchers tracked side effects like injection site reactions, fever, and crying after routine vaccination. The goal was to confirm the vaccine's safety in every…

This study tested a new vaccine called BK1310 in 370 healthy infants to see if it safely protects against several serious diseases: Hib, diphtheria, pertussis, tetanus, and polio. The vaccine was compared to existing vaccines. The goal was to check how well the infants' immune sy…

This study tested a new vaccine called BK1310 in 267 healthy infants to see if it protects against tetanus, diphtheria, pertussis, polio, and bacterial meningitis as well as existing vaccines. Infants received three doses, and researchers measured their immune responses. The goal…

This study tested a booster dose of the DTaP vaccine (BK1301) in 446 adolescents aged 11-12 who had already received the standard childhood series. The goal was to confirm the vaccine boosts immunity against diphtheria, tetanus, and pertussis (whooping cough) safely. Results show…

This study tested a new combination vaccine called Shan6™, which protects against six diseases (diphtheria, tetanus, whooping cough, hepatitis B, Hib, and polio) in healthy infants and toddlers in Thailand. The trial involved 460 participants and compared Shan6™ to a similar 5-in…

This study looks at whether giving the Tdap vaccine every 3 months for a year is safe for healthy plasma donors. Normally, this vaccine is given once every 10 years. The goal is to see if more frequent vaccination produces high levels of tetanus antibodies in the plasma, which co…

This early-stage trial is testing an experimental vaccine designed to protect people aged 6 and older against diphtheria, tetanus, and pertussis (whooping cough). The study will enroll 180 participants to check the vaccine's safety and how well it triggers an immune response. Som…

This trial evaluates whether a hospital-based remedial vaccination strategy can improve Tdap-IPV (tetanus, diphtheria, pertussis, polio) vaccination rates in adults aged 65 and older in the Sarthe region of France. Participants are randomly assigned to receive either the remedial…

This study looked at whether exposure to PFAS chemicals (found in some water supplies) can weaken the body's immune response to the tetanus and diphtheria booster vaccine. Twenty adults from a community with known PFAS exposure received the vaccine and had blood and saliva sample…
