HepadnavirusHBsAgAnti-HBcAnti-HBsVaccineHCCInfection with hepatitis B virus (HBV) may lead to acute or chronic hepatitis. HBV infections were previously much more frequent but there are still 240 million chronic HBV carriers today and ca. 620,000 die per year from the late sequelae liver ...
Once antigens are identified, the immune system develops proteins that circulate in theblood. These proteins are calledantibodies. They fight the infection by killing the antigens. Antibodies are made by white blood cells called lymphocytes, also known as B cells. The main purpose of B cells is...

Prophylactic and therapeutic vaccines Prophylactic vaccines are given to healthy patients to prevent disease before exposure to the aetiological agent. By contrast, therapeutic vaccines are given to patients to cure or ameliorate an existing disease. Hepatitis B virus vaccine Prevents hepatitis B disease ...
If we find that there is evidence of a high level of cat dander or other problem allergens in the building dust, we could design a cleaning regimen that can substantially reduce those levels, ranging from discard of materials to HEPA vacuuming to washing certain surfaces. As this can get cos...
