People over 30 can now book their vaccine appointment from today. Vaccination bookings for people aged 12 and over open on Wednesday 1 September. Anyone who is eligible to book their vaccine now, and is also a parent or guardian of children (12+), can also book appointments for their children. For those aged 16-29 years wishing to book, BookMyVaccine will open for you on September 1. It’s important to remember vaccination sites vary in size and capacity, and with record numbers of bookings, it might be hard to find a booking straight away.
