Filter by:The aim of the study is to evaluate simultaneously the immunological and clinical efficacy and tolerability of an influenza vaccine, inactivated, quadrivalent, with cleaved virus, in patients at risk for severe and complicated influenza routinely vaccinated against influenza in family medicine clinics or specialty clinics (pediatric, internal medicine, cardiology, gynecological diabetes, pregnant women, transplant).
Uing data from a population based cohort in China, we will conduct retrospective cohort study to evaluate the risk of vaccine (e.g., HPV/influenza/rabies vaccine) administered during pregnancy (especially during first trimester) for adverse pregnancy outcomes (e.g., birth defects, preterm birth and low birth weight)
The purpose of this study is to compare the immunogenicity and safety of recombinant zoster vaccine according to CD4+ T-cell count and age in people living with HIV, and to provide evidence to guide immunization of people living with HIV.
In 2021 and following the COVID-19 (corona virus disease 2019) pandemic, different vaccines were initially authorized in Italy and Lebanon. Notably, vaccine side effects were poorly recorded. Thus, the investigator performed a survey study to monitor COVID-19 vaccine side effects among Italian and Lebanese citizens according to gender and age through a web-based questionnaire in Italian and Arabic languages including 21 items by "Google Form", investigating 13 symptoms, and employing social-media platforms
A Phase III, Observer-blind, randomized, active-controlled prospective intervention study
Women's ovarian reserve and fertility were compared before and after 2 doses of vaccination
Prospective observational trial to assess immunological safety (anti-HLA antibodies, donor-derived cell-free DNA) and immunological effectiveness (anti-SARS-CoV-2 IgG) of the first booster dose of SARS-CoV-2 mRNA vaccines in kidney transplant recipients at least one year from transplantation.
This is a phase 3 study, experimental, randomized, double blind, four arm parallel group study, lot to lot consistency. The primary objective of this study is to assess the protectivity of In-House Recombinant Hepatitis B vaccine 28 days after 3 doses immunization.
