[This corrects the article DOI: 10.1371/journal.pone.0027717.].

There are changes to the second through fifth sentences of the fifth paragraph of the Discussion section. The section should be:

Immigrants are required to receive ACIP-recommended vaccines during the exam; therefore, immigrating children receive hepatitis B vaccine [21]. The ACIP currently recommends screening prior to vaccination for all persons born in high-endemicity countries.* The ACIP also recommends hepatitis B vaccine for certain groups of at-risk adults*, but makes no specific recommendation for vaccination of adult immigrants from intermediate- or high-endemicity countries.
