Brief Summary

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.

Detailed Description

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. At present, there is no evidence that these special population have been vaccinated against COVID-19, but CDC vaccination and the guidelines and consensus of various professional societies hold that: (1) the people with underlying diseases have low immunity and are easy to develop into severe patients with high mortality; (2) although there is no direct evidence of evidence-based medicine, it is best to be vaccinated with COVID-19 vaccine in the absence of disease progression activities to reduce high risk. 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.

Primary Outcome Measures
NameTimeMethod
Number of participants with adverse events 60 days after vaccination60 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

Evaluate the safety of the vaccine by observing the occurrence of adverse events(such as fever, dizziness, nausea, headache,fatigue, myalgia, etc) and recording the number of subjects with adverse events.

Number of participants with adverse events 180 days after vaccination180 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

Evaluate the safety of the vaccine by observing the occurrence of adverse events(such as fever, dizziness, nausea, headache,fatigue, myalgia, etc) and recording the number of subjects with adverse events.

Titer and duration of COVID-19 antibody production 15 days after vaccination15 days:Detect the titer and duration of COVID-19 antibodies in the body.

The titer and duration of COVID-19 antibody were produced at 15 days, 30 days, 90 days, 180 days after vaccination, so as to clarify whether the level of immune response to COVID-19 vaccine was affected in people with basic disease.
