Whether is the decision hit according to antibody chroma " strengthen model " vaccinal

Nbsp; 　 asks: My child goes up this year first one, the school organizes vaccine of vaccinal second liver. The teacher says, if already vaccinal before liver crossing second is vaccinal, hit stitch this " strengthen model " vaccine is OK; If do not have have an inoculation to pass second liver vaccine so, this need is hit " common model " vaccinal. Excuse me " strengthen model " what meaning is second liver vaccine? Remind: Precaution of disease of China of 　 of lady of king of reader of Beijing of 3 points 　 controls vaccine of vaccinal second liver Liang Xiaofeng of director of room of central immunization program, liberation army 302 hospitals combine traditional Chinese and Western medicine Liu Shijing of doctor of director of liver ill division answers: Normally, vaccine of inject second liver needs 3 stitches in all, stitch injects when be born, the 2nd needle injects after a month, the 3rd needle injects after 6 months, mention above " strengthen model " vaccinal, not in the vaccinal program that consist in country sets, we are conjectural, its dosage may comparative with the 3rd needle. To already vaccinal the person of vaccine of liver crossing second, through period of time, antibody chroma may be reduced, lose the resistance of pair of second liver virus, need right now again vaccination. But the chroma that wants assay to check antibody first commonly, if chroma is more than 10 international unit / rise, do not need again vaccinal; Otherwise, answer according to " 0, 1, 6 plan " inject again 3 needles are vaccinal. Say so, dozen " strengthen model " vaccinal practice is worth deliberate, if antibody chroma is enough, that adds dozen of stitch again and do not have any meanings; If antibody chroma is insufficient, so if make stitch vaccine only, whats won't be helped.
