As letters have started to arrive inviting 16/17 year olds to walk in sessions for their Covid vaccinations there appears to be an issue with the national Grab a Jab site showing the venues that are available in Lincolnshire.

Lincolnshire health chiefs say the website is not currently showing any sites available even though there are many offering the walk-ins this weekend, including in Grantham.

Rebecca Neno, Director of Covid and Influenza Vaccination Programmes at NHS Lincolnshire CCG said: "Obviously we don't want this glitch with the website to prevent any young person who is wanting their jab to come along this weekend.

"Many of our sites which are listed below are offering walk-ins for the 16 and 17 yr olds this weekend as we try to encourage as many as possible to come along.

"There is no need to make an appointment, and anyone over the age of 16 is invited to just simply turn up. The Pfizer vaccine will be administered on a first come first served basis and at busy times it may be necessary for you to wait."

Lincolnshire CCG says there are walk-in opportunities available to people aged 16 and over on a 'first come, first served' basis as follows:
