Rates of anaphylaxis have increased dramatically since the introduction of the Hib vaccine.
Clin Exp Pharmacol Physiol 1979 Mar-Apr;6(2):139-49 Comparison of vaccination of mice and rats with Haemophilus influenzae and Bordetella pertussis as models of atopy, states “The Haemophilus influenzae vaccinated experimental animal provides a model that is possibly more related to human atopy than the Bordetella pertussis vaccinated animal.” PMID 311260
Ann Allergy 1979 Jan;42(1):36-40 states “To determine whether Haemophilus influenzae could be a factor in human atopy its effects were studied on the (para-)Sympathic Cyclic nucleotide-histamine axis in rats. Haemophilus influenzae vaccination induced changes in the cholinergic system compatible with higher cyclic GMP levels and enhanced histamine release. The authors suggest an involvement of the cholinergic system in Haemophilus influenzae vaccination effects. PMID 216288
Agents Actions 1984 Oct;15(3-4):211-5 entitled Bronchial hyperreactivity to histamine induced by Haemophilus influenzae vaccination states “……This suggests a hyperreactivity of the parasympathethic, cholinergic pathways as a result of H.influenzae vaccination.” PMID 6335351
Eur J. Pharmacol 1980 Apr 4;62(4):261-8 entitled The effects of Haemophilus influenzae vaccination on anaphylactic mediator release and isoprenaline-induced inhibition of mediator release states “These results indicate an increased sensitivity to antigenic challenge and suggest that the functioning of beta-adrenoceptors was decreased as a result of H. Influenzae vaccination.” PMID 6154589
DOES THE PERTUSSIS VACCINE CAUSE ASTHMA, ALLERGIES AND ANAPHYLAXIS?
Pediatrics 1988 Jun (81) Supplement - Report on the Task Force on Pertussis and Pertussis Immunization – extract states, For more than 25 years, it has been known that pertussis vaccine is a reliable adjuvant for the production of experimental allergic encephalitis.4
Bull Eur Physiopathol Respir 1987;23 Suppl 10:111s-113s A model for experimental asthma: provocation in guinea-pigs immunized with Bordetella pertussis states, “ Guinea-pigs were sensitized with killed Bordetella pertussis………the presence of the immediate type of immune response was verified by passive cutaneous anaphylaxis……B. pertussis not only alters adrenergic function but provocation in B. pertussis-sensitized guinea-pigs seems to be a good model for bronchial asthma. PMID 2889487
Pediatr Res 1987 Sep;22(3):262-7 Murine responses to immunization with pertussis toxin and bovine serum albumin: I. Mortality observed after bovine albumin challenge is due to an anaphylactic reaction……….the results of our experiments have established that the disease induced by coimmunizing mice with Ptx and BSA is due to an immediate type hypersensitivity…………PMID 3309858
Infect Immun 1987 Apr.;55(4):1004-8 Anaphylaxis or so-called encephalopathy in mice sensitized to an antigen with the aid of pertussigen (pertussis toxin), states, Sensitization of mice with 1mg of bovine serum albumin (BSA) or chicken egg albumin (EA) ………….induced a high degree of anaphylactic sensitivity when the mice were challenged i.v. with 1 mg of antigen 14 days later. PMID 3557617
JAMA 1994 Aug 24-31;272(8):592-3 Pertussis vaccination and asthma: is there a link?
A study of 450 children, 11% of the children who had received the pertussis vaccination suffered from asthma, as compared with only 2% of the children who had not been vaccinated. PMID 8057511
Allergy 1983 May;38(4):261-71
The non-specific enhancement of allergy. III. Precipitation of bronchial anaphylactic reactivity in primed rats by injection of alum or B. pertussis vaccine: relation of response capacity to IgE and IgG2a antibody levels. …..These results show that injection of alum or B. pertussis vaccine without antigen can precipitate/enhance anaphylactic response capacity and production of specific and non-specific IgE and IgG2a. PMID 6307077
The most recent of those articles is dated 1994, which tells me that whatever they were looking at failed to pan out upon further investigation. Also, since I don’t feel like looking up all those references in PubMed, I can’t see the authors, which would tell me whether those studies were conducted independently, or by an author or two with an agenda.
It is not unusual for studies to seem to show a phenomenon that turns out not to be valid upon further examination.
After reading hundreds of studies, I would say that many of them (regardless of the subject) are deeply flawed. Not in their observations, but in their conclusions, which often appear to be bias-driven interpretations rather than solid conclusions based strictly on the data.
For example, how often do we hear now that consumption of sodas causes obesity? Study after study shows a real correlation between soda drinking and obesity. Nevermind that a pattern of overconsumption leads to both the high quantity of sodas consumed and the obesity; because of the correlation, we are to believe that sodas cause obesity. Why not assume that obesity leads to high soda consumption, another conclusion equally supported by the data?
