Final answer:
The claim that there is no vaccine for Hepatitis B is false; a Hepatitis B vaccine, produced using recombinant DNA technology, is available and commonly given at birth to prevent the disease.
Step-by-step explanation:
The statement that there is currently no vaccine available for Hepatitis B (Hep B) is false. A vaccine does exist for Hepatitis B, and it is produced using recombinant DNA technology. This technology involves the creation of a non-infectious subunit viral vaccine derived from hepatitis B surface antigen (HBsAg), which is produced in yeast cells. Furthermore, many children receive their first vaccination at birth with the Hepatitis B shot to protect them from this serious liver disease. Unlike Hepatitis B, where a vaccine is readily available, there are currently no approved treatments or vaccines for Ebola that have been proven safe and effective in humans.
