Filter by:This is a prospective clinical study aiming to investigate on the transplacental antibody transmission post Covid-19 infection during pregnancy.
To evaluate the immunogenicity, lot-to-lot consistency and safety of three consecutive batches of Measles, Mumps and Rubella Combined Vaccine, Live.
Covid-19 vaccines offered a good opportunity to counteract the spread of Sars-Cov-2 infection among the general population, reducing significantly both morbidity and mortality. Nevertheless, after the first and second doses of vaccination (regardless of the type of vaccine used) several women required gynaecological visits claiming menstrual Irregularities or abnormal uterine bleeding. Considering this anecdotal evidence, a questionnaire was designed to investigate systematically whether menstrual Irregularities or abnormal uterine bleeding occurred in a significant percentage of women undergoing first and second doses of covid-19 vaccination.
Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19
Randomized, double-blind, placebo controlled, multi-center clinical trials of the tolerability, safety and immunogenicity of the inactivated whole-virion concentrated purified vaccine against COVID-19, manufactured by FSBSI "Chumakov FSC R&D IBP RAS", on adult volunteers aged 18-60" (Clinical trials, phase I/II). Study purpose is to assess the tolerability, safety and immunogenicity of the inactivated whole-virion concentrated purified coronavirus vaccine sorbed on adult volunteers aged 18-60.
ChAd0x1 nCoV-19 (AZD 1222) is the main vaccine that is planned to roll-out in Thailand and involve vaccinating people especially in high-risk categories. This vaccine is contained in the multiple-dose vial for vaccinating 10 recipients for 0.5 mL each. However, the additional volume of vaccine was overfilled to 6.5 mL per vial which the vaccination can be administered to more than 10 doses. The University Hospital Network (UHOSNET) and Faculty of Medicine Vajira Hospital, Navamindradhiraj University have jointly stipulated the preparation and vaccination of ChAdox1 - n CoV-19 vaccine with 12 doses per vial injection with traditional 21 or 24 G needle. Taken together, The investigators planned to investigate the immune response of participants after first dose of ChAd0x1 nCoV-19 vaccination with such technique
Vaccination against coronavirus disease 19 (COVID-19) is an essential primary prevention tool to limit the health and economic effects of the pandemic. Objectives: To determine the variation in the levels of Immunoglobulin G (IgG) antibodies in health workers who received a COVID-19 vaccine.
The purpose of this study is to test over time immunity to the COVID-19 vaccines. Adults who are receiving COVID-19 vaccines will be invited to participate.
This project involves a social media campaign to increase parent's knowledge and acceptance of the HPV (human papillomavirus) vaccine. The current vaccine protects against nine types of HPV, including seven that are known to cause cancer. The Centers for Disease Control and Prevention (CDC) estimates that the current HPV vaccine could prevent 90% of cancer cases caused by HPV, including cases of cervical cancer, oropharyngeal (mouth and throat) cancer, anal cancer, and others. About 150 and 104 cases of HPV-associated cancers are diagnosed each year in New Hampshire and Vermont, respectively-many of which could be prevented through vaccination. Currently, only 49.8% of New Hampshire adolescents and 44.3% of Vermont adolescents were not up-to-date for HPV vaccination as of 2016. This social media campaign is testing a set of campaign messages with parents locally and nationally to see which messages are most effective in improving their knowledge and acceptance of the vaccine. A study survey link will monitor the number of people reached and will measure parental intention to get their children vaccinated against HPV.
Invasive meningococcal disease and meningococcal meningitis caused by Neisseria meningitidis have their highest incidence in children, with a second peak in adolescents and young adults. The most important disease-causing serogroups are meningococcal serogroups A (MenA) and MenC in Asia, such as China. The specific vaccine use in each country depends on the predominant serogroups, cost, and availability. conjugate vaccines are preferred to polysaccharide vaccines due to their impact on decreasing nasopharyngeal carriage of N. meningitidis and their overall increased immunogenicity in children. This clinical trial is planning to evaluate the immunogenicity and safety of bivalent meningococcal serogroups A and C tetanus toxoid conjugate vaccine in Chinese healthy children aged 3 months to 5 years.
