Multiple Vaccinations and the Enigma of Vaccine Injury
CITATION
Mawson, A.R.; Croft, A.M. Multiple Vaccinations and the Enigma of Vaccine Injury. Vaccines 2020, 8, 676.
SUMMARY
Mawson and Croft have written a comprehensive review article in the journal Vaccines and have investigated the role of multiple vaccinations in long term health effects include neurodevelopmental disorders, allergies, infections and neuropsychiatric disorders. Past research on vaccine adverse events highlighted in the paper includes multiple childhood vaccines as well as multiple vaccines given to military personnel during the Gulf war. Mawson and Croft hypothesize that multiple vaccines trigger the retinoid cascade which initiates apoptotic hepatitis that releases stored vitamin A compounds into circulation in toxic concentrations. Further, the authors link vitamin A toxicity to multiple adverse events following vaccination.
This review article is a very important contribution to the science around vaccine injury, especially injuries following multiple vaccinations which given the bloated CDC infant vaccination schedule is the rule and not the exception. Mawson has previously completed his own study of vaccinated versus unvaccinated children where he found relationships between vaccination status and multiple sequelae including allergic rhinitis, eczema, otitis media, pneumonia and neurodevelopmental disorders (Mawson et al. 2017, J Transl Sci).

Although animal models of SARS-CoV-2 infection may elucidate mechanisms of immune protection, we need observations of enhanced disease in people receiving candidate COVID-19 vaccines to understand the risk of immune enhancement of disease. Neither principles of immunity nor preclinical studies provide a basis for prioritizing among the COVID-19 vaccine candidates with respect to safety at this time.

SUMMARY
Rapid development of an efficacious vaccine against the viral pathogen severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the cause of the coronavirus disease 2019 (COVID-19) pandemic, is essential, but rigorous studies are required to determine the safety of candidate vaccines. Here, on behalf of the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) Working Group, we evaluate research on the potential risk of immune enhancement of disease by vaccines and viral infections, including coronavirus infections, together with emerging data about COVID-19 disease. Vaccine-associated enhanced disease has been rarely encountered with existing vaccines or viral infections. Although animal models of SARS-CoV-2 infection may elucidate mechanisms of immune protection, we need observations of enhanced disease in people receiving candidate COVID-19 vaccines to understand the risk of immune enhancement of disease. Neither principles of immunity nor preclinical studies provide a basis for prioritizing among the COVID-19 vaccine candidates with respect to safety at this time. Rigorous clinical trial design and post-licensure surveillance should provide a reliable strategy to identify adverse events, including the potential for enhanced severity of COVID-19 disease, after vaccination.

SUMMARY
The aim of this study was therefore to analyze the association between COVID-19 related deaths and influenza vaccination rate (IVR) in elderly people worldwide. The results showed a positive association between COVID-19 deaths and IVR of people ≥65 years-old. There is a significant increase in COVID-19 deaths from eastern to western regions in the world. Further exploration is needed to explain these findings, and additional work on this line of research may lead to prevention of deaths associated with COVID-19.

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
Excipients, considered “inactive ingredients,” are a major component of formulated drugs and play key roles in their pharmacokinetics. Despite their pervasiveness, whether they are active on any targets has not been systematically explored. We computed the likelihood that approved excipients would bind to molecular targets. Testing in vitro revealed 25 excipient activities, ranging from low-nanomolar to high-micromolar concentration. Another 109 activities were identified by testing against clinical safety targets. In cellular models, five excipients had fingerprints predictive of system-level toxicity. Exposures of seven excipients were investigated, and in certain populations, two of these may reach levels of in vitro target potency, including brain and gut exposure of thimerosal and its major metabolite, which had dopamine D3 receptor dissociation constant Kd values of 320 and 210 nM, respectively. Although most excipients deserve their status as inert, many approved excipients may directly modulate physiologically relevant targets.

SUMMARY
The Merck Sharp & Dohme Corp aluminium adjuvant ‘amorphous aluminium hydroxyphosphate sulfate’ (AAHS), primarily used in the Gardasil vaccines against human papilloma virus, has been criticised for lack of evidence for its safety. Documentation from Danish authorities and answers from the European Medicines Agency (EMA) suggest that AAHS may not have been sufficiently evaluated. Documentation from the Danish Medicines Agency shows discrepancies in the trial documents of two prelicensure clinical trials with Gardasil in 2002 and 2003. For both trials, the Agency seems to have authorised potassium aluminium sulfate as the adjuvant and not AAHS. In addition, the participants in the trial launched in 2002 were informed that the comparator was saline, even though the comparator was AAHS in an expedient consisting of L-histidine, polysorbate-80, sodium borate and sodium chloride. According to the EMA, AAHS was first introduced in Europe in 2004 as the adjuvant in Procomvax, a vaccine against the hepatitis B virus and Haemophilus influenza type b. The EMA reports that AAHS was introduced without any prelicensure safety evaluation. The adjuvant is described by the company to be both physically and functionally distinct from all other previously used aluminium adjuvants. There is a need for rigorous evaluation of benefits and harms of the adjuvant AAHS.

Vaccine Hesitancy and Attributions for Autism among Racially and Ethnically Diverse Groups of Parents of Children with Autism Spectrum Disorder: A Pilot Study
CITATION
Little is known about how racial/ethnic differences may influence attributions for autism spectrum disorder (ASD) and subsequent vaccine hesitancy, the latter of which refers to a continuum of concerns about vaccine safety that may lead to vaccine delays and/or refusals. Two hundred and twenty‐five parents of children with ASD who were enrolled in the SPARK cohort (Simons Foundation Powering Autism Research for Knowledge) completed the Parent Attitudes about Childhood Vaccines survey and the Revised Illness Perception Questionnaire . 28.9% of respondents (n = 65) were vaccine hesitant (PACV score ≥ 50). Significant differences were observed between proportions of vaccine‐hesitant parents (VHP) in the White sample and combined samples of color (Asian, Black, Latinx, Multiracial, and Other): 22.8% of the White sample (n = 39) versus 48.1% of the samples of color (n = 26). White, non‐hesitant parents more often agreed with the child’s brain structure as a cause of their child’s ASD, while White, VHP more often agreed with the deterioration of the child’s immunity as a cause. All VHP (regardless of race) agreed more often with diet , their own decisions , and vaccines as causes. VHP of color more often agreed with accident or injury , environmental pollution , their own general stress , and their own emotional state as causes. Future work should examine this phenomenon in larger, diverse samples to further understand differences across specific racial/ethnic groups.

Acute exposure and chronic retention of aluminum in three vaccine schedules and effects of genetic and environmental variation
CITATION
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.”

Interacting, Nonspecific, Immunological Effects of Bacille Calmette-Guérin and Tetanus-diphtheria-pertussis Inactivated Polio Vaccinations: An Explorative, Randomized Trial
CITATION
SUMMARY
Certain vaccines, such as Bacille Calmette-Guérin (BCG), have nonspecific effects, which modulate innate immune responses and lead to protection against mortality from unrelated infections (trained immunity). In contrast, in spite of the disease-specific effects, an enhanced overall mortality has been described after diphtheria-tetanus-pertussis (DTP) vaccination in females. This randomized trial aimed to investigate the nonspecific immunological effects of BCG and DTP-containing vaccines on the immune response to unrelated pathogens. The trial results showed Tdap vaccination led to short-term potentiation and long-term repression of monocyte-derived cytokine responses, and short-term as well as long-term repression of T-cell reactivity to unrelated pathogens. BCG led to short-term and long-term potentiation of monocyte-derived cytokine responses. When given together with Tdap or after Tdap, BCG abrogated the immunosuppressive effects of Tdap vaccination.
The data indicated non-live vaccines like Tdap are immunosuppressive. It could mean each non-live vaccine administered could defeat the benefits of all previously administered vaccines. And of course, the general immunosuppressive effect means the person is more susceptible to all pathogens except the ones the vaccine is intended to protect.

Antigenic Drift Defines a New D4 Subgenotype of Measles Virus
CITATION
SUMMARY
Measles virus is a paradigmatic RNA virus, as the antigenic composition of the vaccination has not needed to be updated since its discovery. The vaccine confers protection by inducing neutralizing antibodies that interfere with the function of the hemagglutinin protein. Viral strains are indistinguishable serologically, although characteristic nucleotide sequences differentiate 24 genotypes. In this work, we describe a distant evolutionary branch within genotype D4. Designated subgenotype D4.2, this virus is distinguishable by neutralization with vaccine-induced monoclonal antibodies that target the neutralizing epitope (NE). The subgenotype D4.2 viruses have a higher predominance in countries with intermediary levels of vaccine coverage. Our studies demonstrate that subgenotype D4.2 lacks epitopes associated with half of the known antigenic sites, which significantly impacts our understanding of measles virus evolution.

SUMMARY
In Japan a significant number of adolescent girls complain of unusual symptoms after human papillomavirus (HPV) vaccination that are considered adverse effects of HPV vaccination. However, a causal link between HPV vaccination and these adverse effects has not been demonstrated. In the present study, we investigated autoantibodies against diverse G-protein coupled receptors in the serum of girls who complained of possible adverse effects after HPV vaccination. This preliminary study provides evidence that post-vaccination abnormal autoimmunity plays an important role in the development of unique symptoms after HPV vaccination.

This study’s objective was to assess whether the sequence of diphtheria-tetanus-pertussis vaccine (DTP) and measles vaccine (MV) was associated with child survival. Using a data set previously used to assess non-specific effects of vaccines with no consideration of vaccination sequence researchers found that out-of-sequence vaccinations in children were associated with higher mortality compared with children vaccinated in-sequence.

Prevalence of cervical disease at age 20 after immunisation with bivalent HPV vaccine at age 12-13 in Scotland: retrospective population study. BMJ. 2019;365:l1161.
SUMMARY
This collection of published comments responds to the assertion by Scottish researchers (Palmer et al., 2019) that bivalent HPV vaccination in Scotland has been “highly effective” in lowering the prevalence of pre-malignant cervical disease. The seven commenters make the following points:
- Exley critiques the authors’ “serious omission” in failing to discuss serious adverse events following HPV vaccination; those with “privileged access to human data” should use it “to cover all aspects of both efficacy AND safety of this vaccine.”
- Gervas estimates that 4,300 women would need to receive the HPV vaccine to prevent one case of severe cervical dysplasia (the “number needed to treat”).
- Selley describes secular trends in teen sexual behavior over the study period and asks whether the falling prevalence of pre-malignant cervical disease attributed to the HPV vaccine could be related to changes in sexual behavior.
- Stone calls attention to an article (Castanon and Sasieni, 2018) that reported a “dramatic increase” in England of cervical cancers in the first generation to be targeted for HPV vaccination.
- Thomas contests the lead author’s assertion that “In Scotland, as elsewhere, no serious adverse effects have been demonstrably linked to the [HPV] vaccine,” pointing to reports of several hundred thousand adverse events assembled by the World Health Organization (including 400 deaths) and almost 13,000 reported reactions in the UK, and observes that valid informed consent is not possible without communicating information about these risks.
- Vasquez points to Scotland’s public health campaign to address endemic vitamin D deficiency implemented in “close chronologic proximity” to its launch of HPV vaccination. “Crediting the reduction in HPV-related disease solely to vaccination…is potentially invalid and misleading, especially when the authors make no account whatsoever of the national program for vitamin D supplementation which started in the same timeframe.”
- Miller points out that the Palmer et al. study only included 12- and 13-year-old girls and “did not include older teens and women who are sexually active, have been exposed to HPV prior to HPV-vaccination, and are likely to have significantly worse outcomes than unvaccinated females.”

SUMMARY
The development and wide-spread use of mumps vaccine resulted in a dramatic and sustained decrease in the incidence of mumps disease; however, since 2000, an increase in the size and number of mumps outbreaks in the United States and other countries has sparked renewed interest in the durability of mumps-specific immunity elicited by mumps vaccination. The most likely explanation for mumps cases in previously immunized persons may be secondary vaccine failure, or waning immunity. Researchers examined changes in markers of measles and mumps immunity at two timepoints, approximately 7 and 17 years after two-dose MMR-II® vaccination, and found that the mumps IgG titers exhibited a large and significant decline during this time period. There was a similar discrepancy with measles-specific immune responses.

The authors examined passively collected reports of adverse events following immunization (AEFI) in Zimbabwe from 1997 to 2017. Given widespread underreporting to the country’s still-developing vaccine surveillance system, just 272 Individual Case Safety Reports (ICSRs) were available, of which 11% represented “serious events.” Of these, 6% were deaths and 5% were life-threatening or involved prolonged hospitalization. Measles-containing vaccines had the highest AEFI reporting rate and were also strongly associated with serious events, as was a six-component vaccine containing antigens for oral poliovirus, diphtheria, tetanus, pertussis, Haemophilus influenzae type b and hepatitis B (OPV/DTP-Hib-HepB). The majority of AEFI were systemic (versus vaccine site reactions)—and systemic events, again, were associated with measles-containing vaccines.

IDFPHB conducted an epidemiologic investigation, which identified nine measles cases in a population with high measles vaccination coverage. All measles patients had signs and symptoms consistent with modified measles (i.e., less severe disease with milder rash, fever, or both, with or without other mild typical measles symptoms). A total of 1,392 contacts were identified, and 162 received postexposure prophylaxis (PEP) with measles-mumps-rubella (MMR) vaccine; the remaining contacts were followed for 21 days (one incubation period). No tertiary cases were identified.

SUMMARY
This brief comment disputes as flawed the conclusions of a Cochrane systematic review of human papillomavirus (HPV) vaccine safety (Arbyn et al., 2018). The earlier review reported no increased risk of serious adverse events and dismissed post-HPV-vaccine deaths as a “chance occurrence.” However, other published studies show significantly more serious adverse events in (1) women who received Gardasil versus aluminum placebo and (2) women who received 9-valent Gardasil-9 versus 4-valent Gardasil. Stating that “hard statistical data must take preeminence over the expert’s opinion,” the author argues that Gardasil clinical trial and post-marketing data “should raise a red flag on HPV vaccine safety.”

This article reports limited effectiveness of “catch-up” HPV vaccination in women in their 20s. The vaccine showed “no significant effectiveness” in women who initiated vaccination between 21-26 years of age (or who received less than the three-dose series), in line with other studies that likewise have found no evidence of “any vaccine effectiveness” in women in their mid- to late 20s. [Note: Although the study’s results “conflict” with arguments to extend HPV vaccination to women of older ages, the FDA nontheless approved Gardasil-9 for women and men between ages 27 and 45 in October 2018.]

Vaccine manufacturer control over clinical study reports inhibits independent researchers’ ability to conduct comprehensive and accurate assessments of HPV vaccine safety. Researchers and regulators evaluating reports of HPV vaccine injuries often do not have access to thousands of pages of clinical study results and must rely on short journal publications. Unpublished reports are also far more likely to contain information about harms, including those that are relatively rare. After three years of efforts to obtain “all potentially eligible reports for a systematic review of HPV vaccines,” the authors had received only half “and these were incomplete and contained redactions.”

SUMMARY
Children with autism spectrum disorder (ASD) and concurrent gastrointestinal (GI) symptoms have a more imbalanced immune response, a more disturbed gut microbiome and worse behavioral outcomes (such as irritability, agitation, social withdrawal, lethargy, hyperactivity and noncompliance) than ASD children without GI symptoms. The study additionally looked at typically developing children with and without GI symptoms and found that ASD+GI children stood out compared to those two groups as well. Children with ASD plus GI symptoms may have a “propensity” toward leaky gut that contributes to their other symptoms and clinical outcomes.
