Active clinical trials for "COVID-19"

Urgent vaccine development plus the characteristics of the coronavirus have caused the relatively more safety problems in COVID-19 vaccines than other classic vaccines and unavoidably raises more concerns among those who accept or consider to be vaccinated. Mulberry juice consists of a large amount of anthocyanin. The abnormally high interleukin-17A level is frequently seen in patients with inflammation status or diseases with inflammation features. Some specific anthocyanins can reduce cyclooxygenase and nitrogen oxide, and the pharmacological effect of the major anthocyanin in mulberry juice imitates that of interleukin-17A antagonists. These features make mulberry juice a potential crude material for reducing inflammation and pain induced by COVID-19 vaccinations. The investigators propose a randomized control trial to explore the dose-response effects of three different volumes of mulberry juice on the incidence and severity of COVID-19 induced side effects. The findings should be helpful for nutrition supplementation in COVID-19 vaccinations and may improve public coordination of COVID-19 vaccinations.

This is a prospective randomized controlled trial study to explore whether the combination of Chinese herbal medicine and Vitamin C is effective and safe to prevent COVID-19 transmission among health care workers in Hong Kong Mobile Cabin Hospital governed by the Hong Kong Hospital Authority who have been caring for patients with COVID-19. A total of 652 adults will be enrolled. Eligible subjects who provide written informed consent will be assessed for inclusion/exclusion criteria. All participants are asymptomatic and test negative for SARS-CoV-2 at the study's commencement. Subjects with major medical illness, renal insufficiency and hypersensitivity to Chinese herbal medicine will be excluded. All participants will receive Vitamin C (VC) supplementation and 28 packets of the herbal medicine free of charge and are advised to consume daily for 14 days. After written informed consent, the subjects will be included and randomly allocated to either CHM+VC group or VC treatment.

The objective of this study is to evaluate the immunogenicity and safety of SCTV01E in participants aged ≥18 years and previously fully immunized with mRNA COVID-19 vaccine.

The objective of this study is to evaluate the immunogenicity and safety of SCTV01C in participants aged ≥18 years and previously fully immunized with either inactivated or mRNA COVID-19 vaccine or previously diagnosed with COVID-19.

The objective of this study is to evaluate the immunogenicity and safety of SCTV01C in participants aged ≥12 years and previously fully immunized with inactivated COVID-19 vaccine.

Safety, reactogenicity and immunogenicity study of the vector vaccine GamCovidVac-M for the prevention of coronavirus (COVID-19) infection caused by the SARS-CoV-2 virus with altered antigenic composition with participation of 12-17 years old volunteers.

The purpose of this study is to evaluate the safety of Omicron BA.4/5-Delta strain recombinant novel coronavirus protein vaccine (CHO cells) after vaccination in people aged 18 and over. It is planned to screen 100 subjects who are 18 years old and above and more than 6 months since the last new coronavirus infection or new coronavirus vaccine. All subjects collected venous blood before vaccination, 14 days, 3 months, and 6 months after vaccination for immunological detection of neutralizing antibody of the new coronavirus prototype strain, Delta strain and Omicron strain (BA.4/5, XBB); All adverse events (AEs) within 30 minutes after vaccination, all AEs (including solicited and non-solicited AEs) on days 0-7, all AEs (non-solicited AEs) on days 8-30, and all AEs within 12 months after vaccination were collected. serious adverse events (SAE) and adverse events of special interest (AESI).

Open-label, prospective intervention study of IndoVac® as a single, homologous booster dose

People have had to make a lot of changes to their lives due to the COVID-19 health crisis. Most experts agree that social distancing and other safety measures have taken a toll on people s mental health. Amish and Mennonite communities often have large families. They may have limited access to health care. Their lifestyle is based on interaction and group events rather than technology. So people in Amish and Mennonite communities may experience the pandemic in their own special ways. Objective: To describe the relationship between stress related to the pandemic and self-rated measures of mental health symptoms and distress among Amish and Mennonite people with bipolar disorder and related conditions, and their family members. Eligibility: Adults ages 18 and older who are taking part in the NIMH AMBiGen study (80-M-0083). Design: Participants will be mailed 4 surveys. One survey will ask about depression symptoms. One survey will ask about mania symptoms. One survey will assess a broad range of psychological problems. One survey will assess the impact of COVID-19 on their mental health. They will fill out the surveys 4 times over 24 months. The surveys will not include participants names, just codes. This will help protect privacy. Data collected in 80-M-0083 will be used. This includes data about participants genes, medical conditions, and assessments. Participants will get an 800 number they can call to speak to the research team. They can also write to the team if they prefer. Participants who wish will get referrals for mental health services. Participation will last up to 24 months. There will be an option for recontact in the future.

Immunodeficiency associated with human immunodeficiency virus (HIV) infection could predispose people living with HIV/AIDS (PLHA) to defective serological responses following infection or vaccination. To evaluate the health outcomes of coronovirus disease-2019 (COVID-19) and HIV co-infection, PLHA and HIV-uninfected persons in Hong Kong are invited to join a study for understanding their clinical characteristics and for tracking their levels of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) over a one-year observation period after infection or vaccination. The results could inform the development of prevention and control strategy for PLHA in response to the emerging coronavirus threats.
