As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic event following the administration of the vaccine.
Influvac should under no circumstances be administered intravascularly.
Antibody response in patients with endogenous or iatrogenic immunosuppression may be insufficient.
Effects on the Ability to Drive or Operate Machinery: Influvac is unlikely to produce an effect on the ability to drive and use machines.
Use in pregnancy & lactation: The limited data from vaccinations in pregnant women do not indicate that adverse fetal and maternal outcomes were attributable to the vaccine. The use of Influvac may be considered from the 2nd trimester of pregnancy. For pregnant women with medical conditions that increase their risk of complications from influenza, administration of the vaccine is recommended, irrespective of their stage of pregnancy.
Influvac may be used during lactation.
