All that about less chance of not contracting Covid with a vaccine..
October / November 2020 we all had no vaccine , my Mrs caught it she was ill two days of the 14
I slept in the same bed with her for two weeks of isolation , nothing changed as regards staying away , I didn't catch it and neither did my kids
January 2022 three jabs for the pair of us , my eldest son one jab(14 years old) no jab for my 10 year old son ...we all catch it .
Just my experience .
