MVC COVID-19 vaccine is a protein subunit vaccine that contains recombinant spike protein of SARS-CoV-2 virus and has been authorized for emergency use by the Taiwan Food and Drug Administration, Ministry of Health and Welfare.

For the Emergency Use Authorization information, please refer to the announcement of the Ministry of Health and Welfare.

For the Government-funded Vaccination, please refer to the official website of the Centers for Disease Control.


  1. The antigen is recombinant spike protein (S-2P) which is licensed from US NIH. The recombinant S-2P protein can maintain the trimeric pre-fusion form to make the antigen more stable.
  2. With adjuvant of aluminum hydroxide and CpG 1018 developed by Dynavax.


  • On 14 February 2022, MVC COVID-19 vaccine has been authorized for emergency use by Paraguay's regulatory authority, Dirección Nacional de Vigilancia Sanitaria (DINAVISA).
  • On 27 October 2021, MVC-COV1901 was selected for WHO COVID-19 Solidarity Trial Vaccines.
  • On 19 July 2021, MVC COVID-19 vaccine has been authorized for emergency use by Taiwan FDA.
  • In June 2021, the independent data monitoring committee (IDMC) conducted an interim analysis of the study. The data showed that MVC COVID-19 vaccine did not elicit serious adverse reactions and is safe and well tolerated.
  • The large-scale Phase II clinical trial for MVC COVID-19 vaccine initiated at the end of 2020, and completed the enrollment of 3,015 subjects within 3 months.
