There is absolutely no need for this kind of error, since the CDC is well aware Taiwan is not part of China and lists the island separately on its pages for individual diseases and separately in the drop-down menu for the customer satisfaction survey that may appear when you access the site. For example, the page on Japanese Encephalitis, a dangerous disease which your children should be vaccinated for has separate entries for Taiwan and China.
The CDC is a US government agency and should follow US government policy, which is that Taiwan's status is undetermined.
The CDC does have a disclaimer:
The boundaries and names shown and the designations used on maps do not imply the expression of any opinion whatsoever on the part of the Centers for Disease Control and Prevention concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.Sure, the disclaimer may say that the CDC takes no position, but if you write (China) under the name Taiwan when that status is disputed, you've taken a position. Drop them a polite line; if they survey you when you enter the website, leave a message on the bottom of the survey too. It's confusing to have the China notices mixed up with Taiwan; it leaves they impression that Taiwan has China's health issues. Contact page for the website is here.
