Good question. In Canada it’s something you’d have to pay for (or have private benefits for) because it was seen as only necessary for international travel. If you ask for it, no doctor is going to say no (if you’re willing to pay for the drug). Maybe US recommends more because the people making the recommendations know they won’t have to pay for it and take the lowest-risk approach regardless of cost. Largely you didn’t need it if your food handling/hygiene standards are good, but when you flash freeze foods from anywhere, you dial up the freshness and risk.
