Participants who had received first dose of HBV vaccine were 12 of which 314.28 had low immunity level while 912.5 had protective immunity level. Participants who had received second doses of the vaccine were 1111.96 of 29.52 had low HBV immunity level where as 912.5 had protective immunity level. Participants who had complete HBV vaccine doses 3 doses were 5256.52 of which 29.52 had low immunity level while 5070.42 had protective immunity level.

Conclusion:

The research concluded there is need for completion of HBV vaccine schedule of the three doses so as to increase the immunity level since 70.42 of respondents who had completed the three doses had protective immunity levels above the cutoff point recommended by the WHO 10 mIU/ml.
