Contraindications

• Anaphylactic reaction following a prior dose of HepB.
• Persons with hypersensitivity to yeast, yeast products or any vaccine component.
• Defer vaccination in persons with moderate or severe acute illness until illness subsides.
• Prefilled syringes might contain natural rubber latex, which might cause allergic reactions in persons who are latex-sensitive.
• The safety and effectiveness of Heplisav-B and PreHevbrio have not been established in adults on hemodialysis.
• Data are not available to assess the effects of Heplisav-B and PreHevbrio on breastfed infants or on maternal milk production and excretion.
• Data on Heplisav-B and PreHevbrio are currently insufficient to inform vaccine-associated risks in pregnancy. Thus, providers should vaccinate pregnant persons needing HepB vaccination with Engerix-B, Recombivax HB, or Twinrix.
