Can a Mantoux tuberculin skin test (TST) be administered in a close window to the COVID-19 vaccine?

If someone had a recent TST, they should still receive the COVID-19 vaccine. The only concern is if the TST is placed in proximity to where the COVID-19 vaccine was administered because the person reading the TST may not be able to clearly determine a positive TST versus the vaccine local reaction. Therefore, the TST should be placed in a different location from the site of the COVID-19 vaccine administration, if happening concurrently.
