Quizplus · Accepted Answer

The vaccine for HBV is prepared from genetically modified yeast that produces a viral surface antigen. This antigen is then purified and used to induce an immune response in individuals, providing active immunity against HBV. Option A (viruses grown in tissue culture) and D (viruses grown in embryonated eggs) are commonly used to produce other vaccines but are not the method of choice for the HBV vaccine. Option C (pooled gamma globulin) is not a vaccine but rather a treatment for individuals with acute HBV infection. Option E (viral particles in patients) is not a method of vaccine production.
