The objective of this study is to determine whether oral NAC is effective at attenuating COVID-19 disease symptom severity and duration of symptoms.
The aim of the COVAG study (Covid-19 Antigen study) is to assess the diagnostic efficacy of two of the most used rapid antigen tests (Roche & Abbott). The study will be performed at the Corona Test Center Stuttgart Cannstatter Wasen. Approximately 2000 patients will be enrolled after having signed the Informed Consent Form (ICF). Each patient will receive 3 nasopharyngeal swabs. Two for the rapid antigen tests from Roche and Abbott and one for the RT-PCR. Furthermore an anamnesis, short clinical examination and blood draw is done. The blood is examined for SARS-CoV-2 antibodies and basic laboratory tests to be communicated to participants.
SARS-CoV-2 infection in pregnancy is associated with an increased risk of adverse maternal and perinatal outcomes. One explanation is that the infection might increase the existing pregnancy-associated prothrombotic status, leading to a higher risk of placental and vascular complications. Administration of low-dose acetylsalicylic acid (LDASA) has shown to improve maternal and perinatal outcomes in women at high-risk of endothelial and placental complications. However, there are no data on the effect of LDASA in preventing complications in SARS-CoV-2- infected pregnant women. To reduce SARS-CoV-2- related complications in a highly vulnerable group to the infection, we will carry out this randomized, double-blind, placebo-controlled multicentre trial in 400 SARS-CoV-2-infected pregnant women. The study main objective is to evaluate the efficacy and safety of LDASA administered up to 36 weeks of gestation in SARS-CoV-2-infected pregnant women in reducing the incidence of adverse maternal and perinatal outcomes. Pregnant women tested positive up to 32 weeks of gestation with a SARS-CoV-2 rapid antigen or PCR test and agreeing to participate, will be randomised 1:1 to receive daily LDASA (125 mg) or placebo up to 36 weeks of gestation and be followed-up until delivery.
The investigators used a retrospective review of 251 SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) positive patients' cesarean section anesthesia to determine the rate of failed spinal anesthesia, management techniques for failed block, and risk factors that contribute to failure in this study.
The purpose of this study is to evaluate the efficacy, safety and immunogenicity of GX-19N in healthy individuals who have received one of COVID-19 vaccine authorized for emergency use.
This study will conduct an evaluation of a program that is being implemented SickKids / Toronto Public health that provides take-home saliva testing kits in schools. Operationally, there is a planned randomization so that all schools have an equitable chance to receive the intervention at various time periods during the planned operational roll-out, which will require a staggered implementation consistent with the stepped-wedge study design. The study will leverage this chance implementation to do a robust evaluation of the public health intervention. Schools that are not being rolled out to week one, will begin in the "control phase" (testing at an assessment center) and transition to the program "intervention phase" (take home saliva kits available at schools) at a randomly assigned time (wedge) over a 6-week period with all schools receiving the program by the end of the study. The investigators will evaluate the impact of the program on SARS-CoV-2 case identification in schools.

Investigators will evaluate the immunogenicity of a third dose of mRNA-1273 SARS-CoV-2 vaccine among cancer patients receiving the recommended third vaccine dose
