Ads that have nurses/doctors/health care workers in them
Ads that depict 'remember when we could before covid' such as go to movies, museums, restaurants, etc freely and unafraid (honestly, I'm afraid of going to most public places now, side note, I have covid again, so my fear isn't really irrational). So ads for those places.
Ads for pizza! Pizza places, pizza kits, etc
ETA: Regarding the Before Covid event, whereas now places are open/opening up, masks are usually required and we didn't have to do that before, not to mention keeping our distance from others, and needing to ensure we used hand sanitizer like Lady Macbeth washing her hands.
