COVID-19 vaccine, heterologous prime-boost, ChAdOx1, coronavac, Sinovac.Tuberculin Skin Test (TST) is currently the standard test for latent tuberculosis (TB). Nevertheless, a drawback of this test is it may provide false positive results in participants who have received BCG vaccine. Interferon Gamma Release Assays (IGRA) have been used to overcome this limitation and could provide more a accurate result. However, the assay needs experienced operators and is costly, which limits its implementation. Mtb antigen-based skin tests (TBST) have recently been approved as
