Why isn't the herpes zoster (shingles) vaccine covered?

No - the Vaccine Injury Program only covers vaccines commonly administered to children.

When Congress created the National Childhood Vaccine Injury Act in 1986, the intention was to only include vaccines that a person would receive as a child.  The shingles vaccination is typically administered to adults over 50 as recommended by the Centers for Disease Control and Prevention.  The NCVIA (now known as the VICP) has not been modified to include other non-childhood vaccinations.  Therefore, certain vaccinations are not covered by the vaccine program including Zostavax and Shingrix.
