You were required to request and document the vaccination status of all personnel no later than June 1, 2021. For workers who were not fully vaccinated or declined to disclose their vaccination status, you were required to request updated vaccination status every 14 days thereafter (e.g., June 15, June 29, July 13, etc.). If you have not yet completed two rounds of ascertainment of vaccination status, you must complete the first round immediately and the second round 14 days thereafter.
