People who have rearranged an initial appointment are expected to receive their first dose shortly, said the Government.

"For anyone who hasn't yet come forward, we urge you to do so now.
"We have made getting a vaccination easier than ever - head to one of the drop-in clinics being offered across the country or, if you prefer, book an appointment online at NHS Inform.
"All of the evidence says that the vaccines are working as we continue to battle the faster-transmitting Delta variant which is now dominant, so I urge everyone to take advantage of the vaccination programme which is open to every adult in Scotland ."
Official figures published on Friday showed that 3,963,502 people have received the first dose of Covid vaccine and 2,940,202 have had their second dose.
