How long should you wait following the use of corticosteroids or progesterone to administer ENDOVAC-Equi®?

The time that steroids last in the system varies greatly between compounds. Some clear the system in as little as 48 hours, others may last 2 weeks. It is generally recommended that there should be a 30 day interval between steroid administration and vaccination to allow adequate time for steroids to clear and the immune system to recover.
