I have finally had to block NHS No-Reply, NHSBooster and NHSvaccine because I am getting multiple texts a day from each number about booking my booster. I have had 5 so far today.
On top of this I am getting emails rom two different addresses and constant adverts EVERYWHERE from web to TV "Gently reminding" me I need to book a booster. I had my booster weeks ago 
I get it. It needs to be advertised for the reluctant but come on. I don't need upwards of 6 reminders a day in text messages alone.
YABU - People are stupid and need reminders every 3 hours over the day
YANBU - This is excessive
