NCT06067555
The goal of this study is to characterize the immune response, both innate and adaptive, as well as locally and systemic, to intradermal (ID) vaccination in healthy individuals. The intervention involves intradermal administration of an FDA-approved intramuscular seasonal influenza vaccine, using an FDA-approved device MicronJet. Investigators will measure antibody titers, cell subtypes, and multi-omic profiles, by collecting skin and peripheral blood at baseline and at several time points after vaccination. The primary objective is to identify baseline correlates of immune response in the skin and peripheral blood to the seasonal influenza vaccine. The investigators secondary goals are to describe the inflammatory response in the skin over time.
NCT05431933
Eupolio is inactivated poliovirus vaccine (IPV). Major purpose of this study is to evaluate safety of Eupolio in 2,000 infants. In addition to the safety, long-term protection after completion of the three primary vaccinations and extent of protective level after a single boosting dose of Eupolio will be evaluated. As IPV plus bOPV vaccination schedule (3 doses of bOPV plus 2 doses of IPV in infant-toddle vaccination schedule) has been implemented in some countries, this study will also evaluate Eupolio's safety and protective effect in that schedule.

NCT05116748
Background: ISHLT and AASLD guidelines recommend SARS-CoV2 vaccination in all individuals undergoing lung and liver transplantation, but there are currently scarce data on the safety and efficacy of these vaccines in this population. In Italy, immunocompromised patients have received the indication to be administered mRNA vaccines only. Primary outcome: safety and reactogenicity Secondary outcomes: immunogenicity and prevention of COVID19 Visits and timepoints: * T0: before first dose administration: visit and venous sampling to assess baseline COVID19 serum status * Telephone calls to assess safety and reactogenicity 1 and 2 days after each dose of vaccination * T21 or 28 (based on vaccine; mRNA BNT162b2 and mRNA-1273, respectively): visit, venous sampling to assess immunogenicity * Follow up visits after 60, 120, 180 and 365 from T0: visit and venous sampling to assess immunogenicity

NCT06066294
The goal of this clinical trial is to compare WHO recommended PrEP Vaccination Schedule, 2 doses 0.2ml 2 sites (0.1ml each site) on day 0 and day 7 and Government of India currently recommended PrEP Schedule, 0.1ml 3 doses on day 0, day 7 and day 28 in Healthy subjects above 18years of age, willing to volunteer and sign written informed consent for the study. The main questions it aims to answer are: * To assess the seroconversion (? 0.5 IU/mL) of the study subjects following primary \& boosting vaccination on Day 35 ,Day 365, Day 372/375. * To assess the incidence of adverse events(immediate/delayed, local/systemic) among subjects. Participants will be administerd with WHO Pre-qualified rabies vaccine (Rabivax-S) . Researchers will compare the two regimens mentioned above.
NCT05515081
Longitudinal study on healthy subjects to investigate the longevity of the antibody response to the Pfizer-BioNTech COVID-19 vaccine. Venous blood samples will be collected on an outpatient basis from 400 adults at regular intervals (1, 2, 4, 6, 12, 18 and 24 months) after the second dose of the vaccine. In the event of the administration of a third dose, the participants already recruited will be subjected to a venous blood sample immediately before administration and subsequently at regular intervals (1, 2, 4, 6, 8 and 12 months). A laboratory serological test will be performed for each sample. The expression of humoral biomarkers will be evaluated with the Luminex methodology with the aim of identifying prognostic and predictive biomarkers of the response to the vaccine.
