About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 6 months

  2. Serum specific antibody

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

    Measured: 6 months

  3. Virus neutralizing antibody titer

    Virus neutralizing antibody titer of Covid-19.

    Measured: 6 months
