Well, there’s a new vaccine for hepatitis A being recommended for most children over 2 years old, as part of a brand new category in the Vaccine Schedule. And the disease itself – hepatitis A is not a big problem because in the vast majority of cases the individual never even knows the disease is present.

The best way to prevent hepatitis A is through vaccination with the hepatitis A vaccine. Vaccination is recommended for all children age 12 months or older, for travelers to certain countries, and for people at high risk for infection with the virus. The hepatitis A vaccine is given as two shots, six months apart. The hepatitis A vaccine also comes in a combination form, containing both hepatitis A and B vaccine, that can be given to persons 18 years or older. This form is given as three shots, over a period of six months or as three shots over one month and a booster shot at 12 months.

Thus the need for boosters. Get the idea – if the vaccine worked, we wouldn’t need boosters after 6 months or a year. Following this shaky logic, if the immunity only lasts a year, the child should get boosters every year for the rest of his life. Now, the booster shot and the first vaccination shot are identical.

Merck also has a hepatitis A vaccine – Vaqta. The CDC’s mandated schedule is the brass ring that all vaccine manufacturers are going for – approval of a vaccine can mean annual revenues of $1 billion or more, which is about what Merck pulls in for their current Hepatitis B vaccine.

Reviewed by Melinda Ratini, DO, MS on July 19, 2016. Hepatitis A and hepatitis B are two members of a family of closely related diseases -- the others being hepatitis C, D, and E -- that are caused by a viral infection. Although each of those viruses is different, the diseases are similar.

Hepatitis B vaccine is a vaccine that prevents hepatitis B. The first dose is recommended within 24 hours of birth with either two or three more doses given after that. This includes those with poor immune function such as from HIV/AIDS and those born premature.

Hepatitis causes inflammation of the liver, and it can be serious or even life-threatening. Although there are no vaccines for hepatitis C, D, or E, there are safe and effective vaccines that can prevent hepatitis A and B. There is also a combination vaccine that guards against both diseases.
