Idet der dog findes utilstrækkelige data angående hepatitis B vaccinens sikkerhed når man administrerer yderligere doser udover det anbefalede 3- dosis program, anbefales revaccination ikke rutinemæssigt efter primærimmuniseringen er fuldført.
However, because data are insufficient concerning the safety of hepatitis B vaccine when additional doses in excess of the recommended series are administered, revaccination following completion of the primary series is not routinely recommended.
