@HFCAMPO
Sorry to say, but you are the person who began and falls into the "confuse you even more regarding your question"
I posted two links that addressed Natsymir's question directly and didn't rail against or evangelize vaccines. Your reply decidedly turned this into a pro/anti vaccine thread. I'd prefer not to have this spiral into a bloated thread similar to the Laowai thing, so I think comments from now on should address the OP's question.
HFCAMPO, appreciate your other insightful posts related to travel. We disagree on vaccines, but adults can agree to disagree.
