hi nagashree,
here in HK, Hepatitis-B vaccine is given in the hospital of delivery...1st dose the day baby is born, 2nd dose when baby is 1 mnth old and third dose when baby is 6 mnths old..and they record all the vaccines and date given on a health record book...i suggest your friend to approach the hospital and ask them to refer their records for information...in any case it is better to consult a pediatrician for advise regarding this..for other friends who read this, it is better to write down all the vaccine info and dates in a diary because immunization is very important to prevent life threatening diseases...
