Filter by:On 11 February 2020, the International Committee for the Classification of Viruses named the disease caused by SAＲS-CoV-2 infection in humans as the new coronavirus pneumonia (coronavirus disease 2019, COVID-19).Due to the decline of immunity and cardiopulmonary function in patients with basic diseases (hypertension, diabetes, chronic obstructive pulmonary disease, chronic kidney disease, cancer diseases, etc.), COVID-19 's severe illness and mortality mainly increase in these special population. Vaccination of COVID-19 vaccine can effectively prevent COVID-19 virus infection and delay or prevent patients from developing into critical illness and reduce mortality.To evaluate the safety and effectiveness of the population vaccinated with COVID-19 vaccine, and to play a scientific and theoretical supporting role in guiding COVID-19 vaccination scientifically, reasonably and effectively, so this study was carried out.
On 11 February 2020, the International Committee for the Classification of Viruses named the disease caused by SAＲS-CoV-2 infection in humans as the new coronavirus pneumonia (coronavirus disease 2019, COVID-19). Due to the characteristics of liver microcirculation disturbance and immune function disorder in patients with chronic liver diseases (such as immune liver disease, chronic hepatitis C, liver cirrhosis, liver cancer, etc.), those patients has a higher risk of infection than the general population during the epidemic period. More attention should be paid to personal protection and disease prevention. Vaccination of COVID-19 vaccine can effectively prevent COVID-19 virus infection and delay or prevent patients from developing into critical illness and reduce mortality. To evaluate the safety and effectiveness of COVID-19 vaccine in those patients with chronic liver diseases, and to guide the COVID-19 vaccination more scientifically, reasonably and effectively, this study was carried out.
This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.
