Bottom paragraph on page reads as follows
Please note that this DPS opportunity was published on 13 June 2022 and is open until 12 June 2024 (i.e. two years). However, due to system issues both the start and end date in this notice are showing as 12 June 2024 with a closing date of 11 June 2024.This is incorrect and the start date for when the DPS opportunity opened is 13 June 2022 and the closing date is 12 June 2024
I read this as they are selling them now and for the next two years, monkeypox and covid 22,23,24 on their way.
