    • Contraindication: patients with history of Guillain-Barré 6 weeks after previous influenza vaccine dose.
  • HBV: Single-antigen recombinant HBV vaccine with a novel cytosine-phosphate-guanine 10-18 oligodeoxynucleotide adjuvant (Heplisav-B) is recommended for HBV prevention in adults aged >18 years.
    • Routine administration is 2 doses, >4 weeks apart; substitution in a 3-dose series with a different vaccine is acceptable, but vaccine from same manufacturer should be used to complete series when feasible.
