Second Doses and Appointment Cancellations

As set out by the Joint Committee for Vaccination and Immunisation (JCVI) a period of 56 days (8 weeks) from the first dose must have passed before a second dose can be given.  (We follow JCVI Guidance and vaccinations cannot be given earlier than 56 days for travel reasons.)

A longer period can take place between doses if it is not possible to attend at the 8 week timescale.

ALL second doses AstraZeneca at Priory House and Biggleswade Hospital have been cancelled. Everyone was informed by text to the mobile number they registered with. If you haven’t heard please rebook as soon as possible via the  National Booking System or calling 119. Alternatively please attend one of the drop-in sessions listed this week. Drop-in Sessions – BLMK CCG

Do not attend for your second dose of AstraZeneca at Priory House or Biggleswade Hospital as the facility is no longer available for second appointments of AZ…

If you don’t have an appointment for your second dose

Some people may be feeling concerned that they haven’t received an appointment for their second dose yet. This will be because centres are not booking people in until they have had confirmation of vaccine supply.

Nobody will be forgotten.

If you received your first vaccine through an appointment made by your GP Practice, they will contact you by the 8th week to book you in. If you are already in your 8th week and haven’t received an appointment please contact your GP in the first instance.

If you received your first vaccine by calling 119 or booking on-line at please go back through this method to book your second dose. Don’t be concerned if you can’t see an appointment straight away, bookings are released daily, so keep trying.

Alternatively, keep an eye out for drop-in clinics where you can get your second dose of AstraZeneca as long as it is 8 weeks after your first one, you must bring your card from your first appointment.

If you already have an appointment for your second dose

The Government and the JCVI have announced that second dose appointments will be brought forward from 12 to 8 weeks for those aged 50 and over who have yet to receive theirs. Nobody needs to contact the NHS.

If your original appointment was with your GP, they will contact you and rearrange.

However, if you already have a second dose appointment that is soon, we would recommend keeping that appointment.

How to bring your appointment forward

If you booked through the National Booking System and have been contacted to bring your appointment forward you should:

  1. Go to and click on book or manage your Covid-19 vaccination
  2. On the main booking page, click on manage my appointments
  3. Enter your personal details and then the booking reference for your existing second dose appointment. This can be found in your text or email confirmation of your booking if you provided your contact details.
  4. When you are in your appointment page, in order to book an earlier appointment, you will first need to cancel your existing appointment by clicking on cancel appointment. NOTE: It is not currently possible to see what other appointments are available until you have cancelled your existing appointment.
  5. When you have cancelled your appointment you can book a new appointment. Any new appointments offered to you will be in line with the JCVI and government guidance, i.e they will be 8 weeks after your first dose appointment or as soon as possible after that.

People can also ring 119. Please note that call handlers in 119 use the same system to book appointments as is available on so the call handler will need to cancel the existing appointment before seeing what time, date and location options are available for booking an earlier appointment.

To get maximum protection everyone will need to get a second dose. Over 20 million people have already had both doses, and we are urging people to come back when they are contacted or if they have an appointment booked.

People who booked online can remind themselves of the place and time of their second dose using the ‘manage my appointments’ section on If your first dose was through your GP they will be in touch 7 – 8 weeks after your first appointment to book your second vaccination.


In order to bring people’s second appointments forward to the revised 8 week period we are in the process of cancelling AstraZeneca appointments that were booked at Priory House and Biggleswade Hospital vaccination centres.

If you had an appointment booked for your second dose of AstraZeneca at either Biggleswade Hospital or Priory House, Shefford it has been cancelled and an earlier appointment is available at The Rufus Centre in Flitwick or The Weatherly Centre in Biggleswade. This will need to be rebooked through the National Booking System by either calling 119 or on-line at

Alternatively, as long as your original appointment was over 8 weeks ago you can use the drop-in facilities. For the latest information on drop-in clinics go to
