Final answer:
A vaccine is currently available only for Hepatitis B among the major bloodborne pathogens listed. The Hepatitis B vaccine is produced using recombinant DNA technology. No vaccine exists for HIV, and while there are vaccines for various diseases, Hepatitis C also lacks a vaccine.
Step-by-step explanation:
A vaccine is currently available only for Hepatitis B among the major bloodborne pathogens viruses listed, which are Hepatitis B, HIV, Hepatitis C, and Influenza. While there are treatments for HIV, no vaccine has been developed. Hepatitis C does not currently have a vaccine available, and Influenza is not a bloodborne virus, therefore it is not the correct answer to this specific question.
Hepatitis B vaccine production is done using recombinant DNA technology. It's important to note that other forms of hepatitis, like Hepatitis D (HDV), require the presence of Hepatitis B to infect an individual. There is a broad range of vaccines available for various diseases, like Hilary Koprowski's vaccine for polio and the availability of a vaccine for yellow fever. However, the HIV infection is managed with antiretroviral therapy rather than a vaccine, as no effective vaccine has been developed for HIV to date.
