The NHS in England has now updated its system and is accepting COVID booster bookings for three months after the second dose for those aged over 40 years.
You can arrange your booking a month in advance - in other words, from two months (61 days) after your second jab.
The NHS is also working on plans to offer a booster dose to everyone aged 18 years old and over, a booster dose to people aged 16 years old and over with a severely weakened immune system and a 2nd dose to all children aged 12 to 15 years old who are not already eligible. Please note that this is not yet available and details will be shared as soon as the service becomes available.
