If you're fully vaccinated, do you still have to worry about getting Covid or the flu? I do sanitize the handles on carts when I go shopping, but I don't wear a mask.

No vaccine is perfect, The Cold circulating today is quite different than the original strain. The technical term is antigenic drift. that's why there have been boosters. If you are fully vaccinated your odds of catching it are much lower and your odds of serious illness are nearly non-existent. That said if you are at risk, primarily because of age or chronic respiratory issues masking in some situations does add an additional degree of protection.

Covid (and RSV and influenza) are respiratory viruses, they are spread primarily through the air and only very rarely from touch. One possible route would be someone coughing or sneezing on something, then you touching the same area and then you touching you lips or nose. Because the odds are so low we don't bother with sanitizing surfaces.Its not wrong, it just doesn't add very much protection. In terms of contracting them, sanitizing surfaces does very little. There are some bacterial and rare viral infections that are spread by touch, but as long as your skin is intact the odds are extremely low.
