Feeds and calendars follow our twice-daily scheduled checks of the sources — they are not live. See privacy for what a sign-up stores.

Dates are as stated in the source documents. Where a protocol's announcement post and the NHSBSA register disagree, the register wins and the conflict is flagged. Serious Shortage Protocols are archived back to 2019.
