Can someone please explain

it was made clear to us that once vaccinated you still have to protect yourself by ' hands face and space'. You can still get the virus but mildly compared to if not vaccinated. A vaccine isn't 'magic'.

The vaccine isn’t 100% effected as I understand it so there will still be people who will possibly catch it. I don’t want to be one so although I’ve received my first vaccine I will still be doing hands,face,space for now.
