Most household varieties of hydrogen peroxide and vinegar aren't concentrated/strong enough to make paracetic acid. You'd need vinegar of a much higher than 6% concentration typically sold and ideally higher concentration peroxide than the drug store kind (like the kind you could get for industrial applications without a special permit). Not that you should mix household cleaners without a clear understanding of the chemistry but I'm just doubtful this is a risk for most people who don't have access to commercial strength varieties of both.
