Scientists test common vaccine on rare immune disease patients

This study is testing whether the FDA-approved Gardasil 9 HPV vaccine can help prevent HPV-related diseases in people with a rare immune disorder called idiopathic CD4 T cell lymphocytopenia (ICL). Researchers are enrolling 54 adults with ICL and healthy volunteers to receive three vaccine shots over six months. The main goal is to see if people with ICL can develop protective immune responses to the vaccine, as they are at higher risk for severe HPV-related health problems.
