Physiological Finding in Management of COVID 19 Patients
This study utilizes physiological indicators of COVID-19 patients as tools for assessing, tracking, worsening, and improving the clinical symptoms of COVID-19 patients. This study employs simple and easy-to-use assessment methods, which can be further aided by artificial intelligence technology to facilitate early response and medication.

A Study to Learn About How Well Yearly Updates to the COVID-19 Vaccine Work to Protect People From COVID-19 and How Much Money People Spend on Healthcare for COVID-19
The purpose of this study is to learn about how well the yearly updates to the COVID-19 vaccine work in adults (age 18 years and above) with a healthy immune system (the body's cells, tissues and organs that work together to protect your body) and in children (age 6 months to 17 years). This study will use a collection of insurance claims and state vaccine registry data called HealthVerity. All patient names and other identifying information is removed. This study will include children who: * Are 6 months of age to 17 years of age * Are enrolled for at least 6 months in a row in a health insurance plan that provides data to HealthVerity * Are enrolled for at least 6 months in a row in a prescription drug insurance plan that provides data to HealthVerity * Live in the same US state for 6 months in a row * Live in a US state that requires COVID-19 vaccine reporting and provides all vaccine history data to HealthVerity * Do not have mismatches in sex and/or year of birth between any of the available datasets * Do not have records of having had COVID-19 and/or any COVID-19 vaccine in the 90 days before the start of the study This study will include adults who: * Are 18 years of age and older * Are enrolled for at least 12 months in a row in a health insurance plan that provides data to HealthVerity * Are enrolled for at least 12 months in a row in a prescription drug insurance plan that provides data to HealthVerity * Have lived in the same US state for at least 12 months * Live in a US state that requires COVID-19 reporting and provides all vaccine history data to HealthVerity * Do not have mismatches in sex and/or year of birth between any of the available datasets * Do not have records of having had COVID-19 and/or any COVID-19 vaccine in the 90 days before the start of the study This study will use the data that has already been collected, and no treatment or vaccine will be given in the study. People who match the information above will be followed in the HealthVerity database for up to 6 months following the first day that a new COVID-19 vaccine is available. This information will be reviewed to see if any of the following happen: * they had a COVID-19 vaccine * they're diagnosed with COVID-19 in a doctor's office * they visit the emergency department for COVID-19 * they visit urgent care for COVID-19 * they are hospitalized for COVID-19 The experiences of people who received a COVID-19 vaccine will be compared to the experiences of people who did not receive the vaccine. This will help to understand how well the Pfizer-BioNTech COVID-19 vaccine works at stopping COVID-19.

Thrombohemorrhagic Complications of COVID-19
The nature of the planned study: The topic is of an applied nature and is aimed at improving the results of comprehensive treatment of patients with COVID-19, the course of whose disease was complicated by thrombotic or hemorrhagic catastrophes. It is planned to analyze the results of treatment of this category of patients based on the work of several centers that provided surgical care to patients with COVID-19 during the pandemic (8 cities). As a result of the analysis, it is planned to develop algorithms for the prevention and treatment of thrombotic and hemorrhagic complications in patients with COVID-19. The proposed study will be multicenter, cohort, retrospective. The purpose of the study: Improvement of treatment results in COVID-19 patients with thrombotic or hemorrhagic complications Scientific novelty: For the first time, as a result of a multicenter study, it is expected to identify the most effective approach to the treatment and prevention of thrombotic and hemorrhagic complications in patients with COVID-19. For the first time, it is planned to develop and put into practice algorithms for the application of the most effective methods of treatment and prevention of thrombohemorrhagic complications of COVID-19.
