TRUE OR FALSE:
All chronic carriers shed virus

Recommended for Healthcare workers The Advisory Committee for Immunization Practices now recommends routine vaccination for all childrerin the U.S Laboratory
RECOMBINANT HBV VACCINE
28
The first marker that appears at the end of the incubation period.
HBsAg

The concentration of the (blank) continues to ise and peaks about mmidwaipthrough the acute infection.
Surface antigen

After HbsAg is detected in the blood (blank) appears
HbeAg
31
oThis period is referred to as the "core window"
Anti-Hbc
32
Presence of this antigen indicates infectivity
