10-year follow-up after a single pertussis shot
This study checks on people who got a single dose of a whooping cough vaccine about 10 years ago in a previous study. Researchers want to see how well the vaccine is still working and if it is still safe.
Bangkok Noi, Bangkok MetropolisAges Any age - NCT06805994RecruitingPhase 1
Restoring infant nose bacteria after staph treatment
This study tests whether giving a nasal spray of healthy bacteria to infants can restore good germs in the nose after they receive mupirocin ointment to treat Staph aureus. It aims to bring back a healthy nasal microbiome.
Baltimore, MarylandAges birth–60 years - NCT06806137RecruitingPhase 3
Chickenpox vaccine study for healthy toddlers
This study tests how well a second dose of an investigational chickenpox vaccine works and how safe it is in healthy children. Your child would get the first dose between 12-15 months old, then a booster 3 months later.
Salvaleón de Higüey, La Altagracia ProvinceAges 1 year–1.3 years - NCT06806709Recruiting
Testing a needle-less device to reduce blood culture contamination
This study tests a device called PIVO to see if it can reduce contamination when taking blood samples to check for bloodstream infections. If you need a blood culture (a test to find germs in your blood) and have a small IV line (22 gauge or larger), you may be able to join this study.
Caboolture, QueenslandAges 18 years+ - NCT06807736Recruiting
Choosing injectable PrEP for HIV prevention in Cape Town
This study offers three ways to prevent HIV: a shot every two months (injectable PrEP), daily pills, or a vaginal ring. Researchers in Cape Town will help you choose the option that fits your life best.
Cape Town, Western ProvinceAges 15 years+ - NCT06807840Recruiting
Flu infection study at Penn Medicine
This study looks at how people's immune systems respond to the flu. If you have a positive flu test at a Penn Medicine location and are 18 or older, you may be able to join.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06808074RecruitingPhase 4
Inhaled amikacin to prevent pneumonia in cirrhosis patients on ventilators
This trial tests whether inhaling an antibiotic called amikacin can prevent ventilator-associated pneumonia in patients with severe liver disease (cirrhosis) who are on a breathing machine. If you or your loved one is in the ICU with liver issues and needs a ventilator, this study may help reduce the risk of a serious lung infection.
Hyderabad, TelanganaAges 18 years+ - NCT06808451Recruiting
Comparing DNA test vs. standard culture for UTI diagnosis
