Neonatal hepatitis B vaccination: Reevaluating timing and adjuvants for enhanced safety and effectiveness

Abstract

AbstractOur aim is an achievement of a 100 percent vaccination rate without toxic vaccine effects. We did a comprehensive literature review on aluminum neurotoxicity and early neonatal hepatitis B vaccination. We analyzed indications for introduction of early neonatal hepatitis B vaccination and the data on experimental and clinical aluminum‐induced neurotoxicity. It is justified very early hepatitis B vaccination to be carried out in high‐risk endemic areas. In those countries there is a large number of hepatitis B positive individuals, including pregnant women, which leads to a great number of vertical, mother‐to‐child, transmissions of the virus during pregnancy. There is also a serious risk of perinatal Hepatitis B virus infections in such countries. Early neonatal hepatitis B vaccination is also carried out in low‐risk countries, where the number of hepatitis B positive pregnant women is extremely small, making the number of newborns who require the prevention of hepatitis B infection extremely small as well. It is necessary for all vaccines which contain aluminum as an adjuvant to be immediately suspended as children vaccination until they start walking and until aluminum is replaced with calcium, zinc or a nonmetallic adjuvant such as microcrystalline tyrosine or monosodium urate. Meanwhile sustained efforts should be made to create the so‐called mucosal vaccines against diphtheria, pertussis, measles, mumps and rubella. At the same time, all the children born to hepatitis B positive mothers, regardless of their place of birth must be vaccinated against hepatitis B as the benefits from vaccines by far outweigh potential harm caused by adjuvant aluminum.
