  • TB Tests and mRNA COVID-19 Vaccines

    January 7, 2021

    ... There are no data to inform the impact of the COVID-19 mRNA vaccines on either the tuberculin skin test (TST) (administered by intradermal placement of 0.1 cc of purified protein derivative) or the interferon gamma release assay (IGRA). There is no immunologic reason to believe that a TST or blood draw for IGRA will impact the effectiveness of COVID-19 mRNA vaccines.

    ...Although the COVID-19 mRNA vaccine is not a live virus vaccine, not enough is yet known of the potential impact of mRNA vaccines on immune responses to say conclusively whether the COVID-19 mRNA vaccine could have a potential effect on TST or IGRA test results during the first 4 weeks after COVID-19 vaccination.
