Special Precautions
Hexaxim will not prevent disease caused by pathogens other than Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, hepatitis B virus, poliovirus or Haemophilus influenzae type B. However, it can be expected that hepatitis D will be prevented by immunization as hepatitis D (caused by the delta-agent) does not occur in the absence of hepatitis B infection.
Hexaxim will not protect against hepatitis infection caused by other agents such as hepatitis A, hepatitis C and hepatitis E or by other liver pathogens.
Because of the long incubation period of hepatitis B, it is possible for unrecognized hepatitis B infection to be present at the time of vaccination. The vaccine may not prevent hepatitis B infection in such cases. Hexaxim does not protect against infectious diseases caused by other types of Haemophilus influenzae or against meningitis of other origins.
Prior to immunisation: Immunisation should be postponed in individuals suffering from moderate to severe acute febrile illness or infection. The presence of a minor infection and/or low-grade fever should not result in the deferral of vaccination.
Vaccination should be preceded by a review of the person's medical history (in particular previous vaccinations and possible adverse reactions). The administration of Hexaxim must be carefully considered in individuals who have a history of serious or severe reactions within 48 hours following administration of a vaccine containing similar components.
Before the injection of any biological, the person responsible for administration must take all precautions known for the prevention of allergic or any other reactions. As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following administration of the vaccine.
If any of the following events are known to have occurred after receiving any pertussis containing vaccine, the decision to give further doses of pertussis containing vaccine should be carefully considered: Temperature of ≥ 40°C within 48 hours not due to another identifiable cause;
Collapse or shock-like state (hypotonic-hyporesponsive episode) within 48 hours of vaccination;
Persistent, inconsolable crying lasting ≥ 3 hours, occurring within 48 hours of vaccination;
Convulsions with or without fever, occurring within 3 days of vaccination.
There may be some circumstances, such as high incidence of pertussis, when the potential benefits outweigh possible risks.
A history of febrile convulsions, a family history of convulsions or Sudden Infant Death Syndrome (SIDS) do not constitute a contraindication for the use of Hexaxim. Individuals with history of febrile convulsions should be closely followed up as such adverse events may occur within 2 to 3 days post vaccination.
If Guillain-Barre syndrome or brachial neuritis has occurred following receipt of prior vaccine containing tetanus toxoid, the decision to give any vaccine containing tetanus toxoid should be based on careful consideration of the potential benefits and possible risks such as whether or not the primary vaccination has been completed. Vaccination is usually justified for individuals whose primary vaccination is incomplete (i.e, fewer than three doses have been received).
The immunogenicity of the vaccine may be reduced by immunosuppressive treatment or immunodeficiency. It is recommended to postpone vaccination until the end of such treatment or disease. Nevertheless, vaccination of individuals with chronic immunodeficiency such as HIV infection is recommended even if the antibody response may be limited.
Special Populations: No data are available for premature infants. However, a lower immune response may be observed and the level of clinical protection is unknown.
Immune responses to the vaccine have not been studied in the context of genetic polymorphism.
In individuals with chronic renal failure, an impaired hepatitis B response is observed and administration of additional doses of hepatitis B vaccine should be considered according to the antibody level against hepatitis B virus surface antigen (anti-HBsAg).
Precautions For Use: Do not administer by intravenous, intradermal or subcutaneous injection.
As with all injectable vaccines, the vaccine must be administered with caution to individuals with thrombocytopenia or a bleeding disorder since bleeding may occur following an intramuscular administration.
The potential risk of apnoea and the need for respiratory monitoring for 48 to 72 hours should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity. As the benefit of vaccination is high in this group of infants, vaccination should not be withheld or delayed.
Interference with laboratory testing: Since the Hib capsular polysaccharide antigen is excreted in the urine, a positive urine test can be observed within 1 to 2 weeks following vaccination. Other tests should be performed in order to confirm Hib infection during this period.
Effects on ability to drive or operate machines: Not applicable.
