What do measles, polio, rubella and hepatitis B vaccines have in common? They prevent outbreaks of disease. It’s easy to take all that for granted today: dying of measles is so Oregon Trail. But in countries where hepatitis B vaccines aren’t standard, the disease is still common.

And here in the U.S., there’s been an increase in recent years of families opting not to vaccinate their children. In some states, it’s causing cluster outbreaks of totally preventable diseases. And that puts everyone (even those who got their mumps and hepatitis B shots) at risk.

Your Hepatitis B Vaccine can prevent many nasty diseases

Getting your hepatitis B vaccine (and the other vaccines health pros recommend) can prevent a lot of nasty diseases. Like liver cancer.

And even if you got your hepatitis B vaccines when you were young, booster shots every few years are key if you’re in a higher risk population.
