NCT04941079

Brief Summary

This study is a prospective observational study. We aim to investigate the safety and efficacy of inactivated SARS-CoV-2 vaccine between immune-related myopathy (myasthenia gravis and inflammatory myopathy) patients and health controls. The main study factors include adverse events following immunization (AEFI), serum specific antibody (Acetylcholine receptor (AChR) antibody, Anti-MuSK (muscle-specific kinase) antibody, myositis antibody) and virus neutralizing antibody titers.

Outcome Measures

Primary Outcomes (3)

  • Adverse events following immunization (AEFI)

    Adverse event following immunization refers to any untoward medical occurrence which follows immunization and which does not necessarily have a causal relationship with the usage of the vaccine.

    6 months

  • Serum specific antibody

    Serum specific antibody of immune-related myopathy including Acetylcholine receptor (AChR) antibody, Anti-MuSK (muscle-specific kinase) antibody, myositis antibody.

    6 months

  • Virus neutralizing antibody titer

    Virus neutralizing antibody titer of Covid-19.

Study Population

Immune-related myopathy (myasthenia gravis and inflammatory myopathy) patients and health controls who are willing to receive two dose of SARS-CoV-2 inactivated vaccine.

You may qualify if:

  • Complete behavioral ability
  • Voluntary willingness to vaccinate
  • Clinically confirmed immune-related myopathy (myasthenia gravis and inflammatory myopathy) and immune-related myopathy (myasthenia gravis and inflammatory myopathy)was stable
  • Informed consent to the research

You may not qualify if:

  • No independent behavior ability
  • Vaccination is contraindicated
  • Other diseases that significantly affect the immune function
  • Other diseases that may significantly affect immune function are being treated
  • Vaccination contraindication was found during the study observation period
  • Other diseases that may significantly affect immune function were diagnosed during the study observation period
  • Treatments for other diseases that may significantly affect immune function were initiated during the study observation period
  • Refused regular follow-up
