I don’t know if the one I had was a third or a booster! I got a text telling me to book because I am ECV ( third?) and a few days later a letter offering the booster.It is almost like the system is confused.
Those who are immunosuppressed require a third vaccine, followed by a booster in sixth months time.
Being ECV, doesn't necessarily mean receiving a third vaccination. You should have been informed what you are eligble for. There is a code on your medical records, which deems you eligible for a third vaccination, followed by a booster. You should have been told at your latest appointment if you need a booster in sixth months time. This has been decided for all nations in the UK by the JVC.
You can find lots of information about who is eligible on the Versusarthritis website.

In Scotland, those who are deemed to require a third vaccination, followed by a booster, received a letter months ago, informing them of this. Not sure what happens elsewhere.
