没事。可以打四针。只要第四针在6个月就可以了。见： http://www.cdc.gov/vaccines/recs/schedules/downloads/child/2010/10_0-6yrs-schedule-pr.pdf
footnote 1：
After the birth dose:
• The HepB series should be completed with either monovalent HepB or a
combination vaccine containing HepB. The second dose should be administered
at age 1 or 2 months. Monovalent HepB vaccine should be used for doses
administered before age 6 weeks. The final dose should be administered no
earlier than age 24 weeks.
• Infants born to HBsAg-positive mothers should be tested for HBsAg
and antibody to HBsAg 1 to 2 months after completion of at least 3 doses of
the HepB series, at age 9 through 18 months (generally at the next well-
child visit).
• Administration of 4 doses of HepB to infants is permissible when a
combination vaccine containing HepB is administered after the birth dose.
The fourth dose should be administered no earlier than age 24 weeks.
可能因为用的是组合制剂，可以打四次。
