Thanks, John915, as always, you are clear to understand. I'd arrived at a date of April20th-ish myself, BUT I wondered if there may be problems, as we received our injections after a 'phone call bidding us to attend a centre several miles distant - our longest journey during "Lockdown", and quite exciting to get out! Will we ha contacted by that distant place, or from our own GP's surgery - we got "the letter" from them, the day after we'd been "done", inviting us to select a date and venue, but of course we'd already been vaccinated.
TY
