You may have seen in the media that the 2nd doses for those most vulnerable (groups 1-9) are being bought forward from 12 to eight weeks.
You do not need to do anything; people should continue to attend their second dose appointments and nobody needs to contact the NHS or the practice.
The NHS will let those who should bring their appointment forward know, when they are able to do so. Those aged under 50 will continue to get their first dose, with their second dose at 12 weeks, as has been the deployment strategy so far.
