What if a needle is missed?
Get the next needle as soon as possible
What if I decide not to be immunized?
Choosing not to be immunized or delaying immunization puts you/your child at risk of getting sick with Hepatitis B.
Is Hepatitis B vaccine safe?
Yes! You may have no reaction or mild symptoms that include:

- Low fever
- Children may become fussy or sleepier than usual;
These normal reactions usually last between 12 and 24 hours. Hepatitis B vaccine is safe during pregnancy and breast feeding

- crying or fussing for more than 24 hours;
