Combination Vaccines

Combination vaccines reduce the number of injections required at each visit to promote ‘compliance’. For this reason combination vaccines such as MMR are not available as separate vaccines.

Infanrix-hexa combines diphtheria/tetanus/pertussis (DTP), hepatitis B, inactivated polio (with three strains of polio virus) and Hib vaccines (formulated with tetanus toxoid). The final vaccine contains phenoxyethanol, aluminium hydroxide, formaldehyde and antibiotics among other ingredients.

  •  The 5 in 1 vaccine contains more aluminium than any other vaccine.66
  • Not surprisingly combination vaccines record an increase in injection site reactions such as swelling and pain, and
    significantly higher rates of fever.67

As they are administered at the same time as other vaccines, it is impossible to distinguish the cause of other adverse events and no long term studies examine the effects of combining so many vaccines in infants.
