Anyone invited to register for a Covid-19 vaccine is being told not to ring 111 to do so until Saturday (March 6).
Government says the 111 line is experiencing 'unprecedented' levels of calls and, as a result, some cannot be answered at this time.
Officials say this measure is only related to vaccine appointments and anyone with Coronavirus symptoms should continue to report them to 111 as normal.
Letters are being sent this week to the latest priority groups for vaccination, and this process will continue.
