Neutralizing antibody titres are reported in International Units/ml (IU/ml). Booster vaccination is recommended if antibody titre falls below 0.5 IU/ml. Individuals with antibody levels between 0.5 IU/ml and 1.0 IU/ml should be carefully assessed for their risk of exposure; if a booster dose of vaccine is not administered, a new serum sample should be drawn and tested within 3-6 months to ensure that the individual's antibody level does not fall below 0.5 IU/ml.
