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.

Outcome Measures

Primary Outcomes (10)

  • Number of participants with adverse events 15 days after vaccination

    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.

    15 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

  • Number of participants with adverse events 30 days after vaccination

    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.

    30 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

  • Number of participants with adverse events 60 days after vaccination

    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.

    60 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

  • Number of participants with adverse events 90 days after vaccination

    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.

    90 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

  • Number of participants with adverse events 180 days after vaccination

    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.

    180 days:Record the number of adverse reactions such as fever, dizziness, nausea, headache, fatigue, myalgia, etc.

  • Titer and duration of COVID-19 antibody production 15 days after vaccination

    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.

    15 days:Detect the titer and duration of COVID-19 antibodies in the body.

  • Titer and duration of COVID-19 antibody production 30 days after vaccination

    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.

    30 days:Detect the titer and duration of COVID-19 antibodies in the body.

  • Titer and duration of COVID-19 antibody production 60 days after vaccination

    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.

    60 days:Detect the titer and duration of COVID-19 antibodies in the body.

  • Titer and duration of COVID-19 antibody production 90 days after vaccination

    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.

  • Titer and duration of COVID-19 antibody production180 days after vaccination

    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.

    180 days:Detect the titer and duration of COVID-19 antibodies in the body.
