Non-specific and sex-differential effects of routine vaccines
Peter Aaby has >400 studies indexed by PubMed. His findings are fraught with
significance, eg:
Non-specific and
sex-differential effects of routine vaccines: What evidence is needed to take
these effects into consideration in low-income countries?

None of the original vaccines used in the child immunization programmes in
low-income countries, including BCG, diphtheria-tetanus-pertussis (DTP), oral
polio vaccine (OPV), and measles vaccine (MV), were tested for their overall
effect on child mortality before being introduced. It was assumed that the
effect on overall child mortality would be equivalent to the proportion of
deaths caused by the targeted disease(s) (1). However, this is no longer a
tenable assumption. Many studies have shown that these routine vaccines may have
more general effects on the immune system than merely protecting against the
targeted disease, i.e. so-called non-specific effects (NSE) (2). The NSE may
well be more important for overall child survival than the lives saved by
specific disease prevention (2-4).
The WHO´s Global Advisory Committee on Vaccine Safety (GACVS) has recently
stated that it will keep a watch on the non-specific effects (NSE) of
vaccination. GACVS indicated that "conclusive evidence for or against
non-specific effects of vaccines on mortality, including a potential deleterious
effect of DTP vaccination on children's survival as has been reported in some
studies, was unlikely to be obtained from observational studies" (5). By
insisting on new RCTs to provide conclusive evidence, GACVS is making it very
difficult if not impossible to test the NSEs of the currently recommended
vaccines. It would usually be considered unethical to test currently recommended
vaccines as part of a trial withholding these vaccines from some children (6).
