Clinical Trial to Study the COVAC-2 Booster Dose (for COVID-19) in Generally Healthy Adults.

Double Vaccinated for COVID-19 (For Phase 1 of the Study)Acute Respiratory Syndrome Coronavirus 2 (For Phase 2 Exploratory Group)

VIDO has developed a vaccine called COVAC-2. The COVAC-2 study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-2 contains a SWE adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The SWE adjuvant is similar to another adjuvant, MF59, that is found in influenza vaccines and MF59 containing vaccines have been given to millions of people around the world. The vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent severe COVID-19 illness. In animal studies, the immune response generated by the COVAC-2 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. This is a Phase 1/2, placebo-controlled, observer-blind, age-stratified randomized, multicenter study to access the safety and immunogenicity of two dosing levels (10 and 25 µg S1 protein tested in parallel) administered once in healthy adults ≥18 of age who have received 2 doses of an authorized COVID-19 vaccine at least 6 months earlier. The study will also include an open-label exploratory study arm to evaluate safety and immunogenicity of a single COVAC-2 dose in previously SARS-CoV-2-infected individuals (Phase 2 only).

Fourth BNT162b2 COVID-19 Vaccine Dose

COVID-19 Pandemic

The Omicron variant of concern (VOC) is currently rapidly spreading worldwide, with extremely high transmission rates, with an estimated R of >3. the investigators now have preliminary, yet unpublished data, showing slow waning of the immune response after the third dose of the BNT162b2 mRNA vaccine within 4 months after this dose . While these data would not have been worrisome in the Delta VOC era, this may be different with the emergence of the Omicron VOC. These data raise the question of when and will a 4th dose be needed to cope with the emergence of Omicron. However, if a have reached the maximal effect of the current vaccine has been reached against Omicron, with a third dose, will a 4th dose have any added value? Here, the investigators will study the potential immunogenicity of a 4th dose, together with assessing safety and effectiveness in preventing infections

Heterologous Boost Immunization With an Aerosolised Ad5-nCoV After Two-dose Priming With an Inactivated...

COVID-19

This is a multicenter, open-label, partially radomized, parallel-controlled clinical trial to evaluate the safety and immunogenicity of heterologous prime-boost immunization with an aerosolised adenovirus type-5 vector-based COVID-19 vaccine (Ad5-nCoV-IH) after two-dose priming with an inactivated SARS-CoV-2 vaccine (ICV) in adults aged 18 years and above. 10420 healthy subjects aged over or equal to 18 years whom have received two doses of ICV before 6 months or more, will be recruited from six provinces in China in this study.Of them, 10000 eligible participants in an open cohort will receive a booster dose of Ad5-nCoV-IH to evaluate the safety profile. Another 420 participants were involved in immunogenicity cohort and randomized in a ratio of 1:1 to receive a boost of Ad5-nCoV-IH or ICV. The ICV homologous to the priming series will be supplied as the booster. The occurrence of adverse reactions within 28 days and serious adverse events within 6 months after vaccination will be observed in all participants. In addition, blood and saliva samples will be collected from all participants in immunogenicity cohort on the day 0 before and 14, 28 and month 3 and 6 after the booster vaccination. Each subject will remain in this study for approximately 6 months.

The Impact of COVID-19 on Maternal and Neonatal Outcomes

COVID-19Pregnancy; Infection

The novel coronavirus (SARS-CoV-2) infection (COVID-19) has caused a worldwide pandemic. There is still much that is unknown regarding the virus, especially its effects on pregnancy, the fetus, and the neonate. This study seeks to evaluate adverse pregnancy and neonatal outcomes related to COVID-19 infection. The FDA has authorized emergency use authorization for the SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccines from Pfizer and Moderna. Pregnant women were excluded from the Phase III clinical trials of the mRNA vaccines. There are no studies that have evaluated functional antibody responses, antibody reactivity to variant viruses, T cell frequencies or activity, or protection against infection or development of COVID-19. Having a more detailed understanding of how pregnancy and lactation alters the longevity, specificity, and activity of antiviral antibody and T cell-mediated immune responses to COVID-19 mRNA vaccines is essential for the FDA to inform future recommendations and regulation of these vaccines.

Evaluation of the Safety, Tolerability, and Reactogenicity of the Baiya SARS-CoV-2 Vax 2 Vaccine...

COVID-19 Vaccine

The investigational product Baiya SARS-CoV-2 Vax 2 vaccine is a second-generation of protein subunit vaccine from plant. The primary objective aiming to evaluate the safety, tolerability, and reactogenicity of Baiya SARS-CoV-2 Vax 2 in adults (aged between 18 to 64 years, inclusive) after 2 doses of Baiya SARS-CoV-2 Vax 2 given 21 days apart IM, up to 28 days after the second vaccination. The secondary objective aiming to evaluate long-term safety profile (up to 1 year) and evaluate immunogenicity after 2 doses of Baiya SARS-CoV-2 Vax 2 given 21 days apart.

A Live Recombinant Newcastle Disease Virus-vectored COVID-19 Vaccine Phase 1 Study.

SARS-CoV-2

This study will be a phase-1, open-label, placebo-controlled, evaluation of two-dosages of a live, recombinant Newcastle disease virus expressing the spike protein of SARS-CoV-2 (NDV-HXP-S), an investigational product for IN, IM, or a combined IN+IM vaccination in healthy adults previously immunized against COVID-19. The IN and IM live virus vaccinations will be identical in composition and only differ in route of administration.

Patient Reported Health-Related Quality of Life Associated With COVID-19

COVID-19

COVID-19 pandemic elicited broad medical, economic, and social consequences. There is limited research and outstanding data gaps related to understanding the impact of long-term effect of COVID-19 on Health-Related Quality of Life (HRQoL) and Work Productivity and Activity Impairment (WPAI) in the outpatient settings in the US. Information on the evolution of recovery of daily function and the return to the level of health enjoyed by outpatients prior to SARS-CoV-2 infection will inform the overall estimation of the benefits of vaccines (quality-adjusted life years [QALYs] and indirect cost saving) in COVID-19 health economics models.
