Efficacy of PEP for HBV. The effectiveness of hepatitis B immune globulin(HBIG) and/or hepatitis B vaccine in various postexposure settings has been evaluatedby prospective studies. For perinatal exposure to an HBsAg-, HBeAg-positive mother,a regimen combining HBIG and initiation of the hepatitis B vaccine series at birth is85%--95% effective in preventing HBV infection(44,45). Regimens involving either multiple doses of HBIG alone or the hepatitis B vaccine series alone are 70%--75% effectivein preventing HBV infection (46). In the occupational setting, multiple doses ofHBIG initiated within 1 week following percutaneous exposure to HBsAg-positiveblood provides an estimated 75% protection from HBV infection(47--49). Although the postexposure efficacy of the combination of HBIG and the hepatitis B vaccineseries has not been evaluated in the occupational setting, the increased efficacy ofthis regimen observed in the perinatal setting, compared with HBIG alone, is presumedto apply to the occupational setting as well. In addition, because persons requiring PEPin the occupational setting are generally at continued risk for HBV exposure, theyshould receive the hepatitis B vaccine series.
Voice Command was overhauled in 2017, and they're pretty good now. Other smart interfaces were updated in 2018 to search for content and apps and change settings, something Samsung has been able to do for a few years. Even more in-depth stuff like calibration settings are only a button press away, which is quite nice.
