Which statement is correct about hepatitis vaccines options in the United States?

• A. Hepatitis A and Hepatitis B vaccines are available.
• B. Only Hepatitis A vaccine is available.
• C. Only Hepatitis B vaccine is available.
• D. No hepatitis vaccines are available.

Answer: (A)

In the United States, vaccines exist to prevent both hepatitis A and hepatitis B, and vaccination against both viruses is commonly recommended. The hepatitis A vaccine is given in a two-dose series and protects against the food- and waterborne hepatitis A infection. The hepatitis B vaccine is a recombinant subunit vaccine given in a multi-dose schedule and protects against chronic liver disease from hepatitis B infection. There are also combination options, such as vaccines that cover both A and B for certain adults, which further supports protection against both viruses.

Because there are vaccines for the two hepatitis viruses, the statements that claim only one vaccine is available or that no vaccines are available are not correct. It's also useful to note that there isn’t a routine vaccine for hepatitis C, and hepatitis D is prevented indirectly by vaccination against hepatitis B, since HDV requires HBV to infect.
