Between 1990 and 1995, the incidence of pneumococcal bacteremia among adults in Sweden increased 2.6-fold, the same was observed in Norway.Protective effect of breastfeeding: an ecologic study of Haemophilus influenzae meningitis and breastfeeding in a Swedish population. 1999, Silfverdal, Int J Epidemiol
The incidence of Hib before vaccination began was 30/100,000 among whites, and 600/100,000 among Aboriginal people in Alaska. The incidence in the United States increased 4-fold from 1940 to 1970. The same happened in Scotland and Sweden.
Breastfeeding has a protective effect against meningitis caused by Hib, and this effect lasts 5-10 years.
A short period of breastfeeding (less than 13 weeks) increases the risk of Hib 3.79 times. Painful children get sick 4.5 times more often.
Breast milk has an inhibitory effect on the attachment of bacteria to the mucous membrane of the nasopharynx.
As the chart shows, after the decrease in the number of children on breastfeeding, the incidence of Hib increased, and when their percentage increased again, the incidence of Hib decreased.
Among children over 1 year of age, a short period of breastfeeding (HS) is associated with an increased risk of Hib 7.79-fold. Each additional week of HB reduced the risk of Hib by 5%. The protective effect of HB started already with 13 weeks of exclusive breastfeeding, and lasted for months and years.Risk factors for primary invasive Haemophilus influenzae disease: increased risk from day care attendance and school-aged household members. 1985, Istre, J Pediatr
Among children under 6 months of age, exclusive HB is associated with a 90% reduction in Hib risk. Visiting kindergarten - increasing the risk by 1.9-5.9 times. The larger the group in the garden, the higher the risk.Long term enhancement of the IgG2 antibody response to Haemophilus influenzae type b by breast-feeding. 2002, Silfverdal, Pediatr Infect Dis J
Among the sick Hib children, those who were longer on HB, had more antibodies.Why the rise in Haemophilus influenzae type b infections? 2003, Silfverdal, Lancet
In Sweden and Finland, there has been no increase in the number of cases of Hib after switching to acellular pertussis vaccine, the authors believe that this is due to the fact that longer breastfeeding is common in these countries.Immunity and immunization of children against diphtheria in Sweden. 1989, Mark, Eur J Clin Microbiol Infect Dis
The authors measured antibodies level of 2,400 people in Sweden. 19% of people of the age of 20 and under did not have immunity against diphtheria. Among people over 40 years of age, only 15% had sufficient level of antibodies. Among the elderly, 81% of women and 56% of men did not have the immunity. On average, 70% of adult women and 50% of adult men had antibodies level below 0.01 IU/ml.Whooping cough in adults. 1981, Trollfors, BMJ
After 1978, it was discovered that 84% of pertussis patients had been vaccinated with three doses of the vaccine. Consequently, in 1979 Sweden stopped administering the vaccination. Only in 1996, when the acellular vaccine appeared, was vaccination reinstated.
В Швеции уровень СВДС коррелировал с уровнем нитратов в воде.Vaccination and Allergic Sensitization in Early Childhood - The ALADDIN Birth Cohort. 2018, Swartz, EClinicalMedicine
It is known that among people practicing anthroposophic lifestyle, the risk of allergic disease is much lower. Anthroposophic lifestyle is characterized by a preference for home births, a long breastfeeding period, a diet of organic products with an accent on vegetarian diet, limited use of antibiotics and antipyretics, and low level of vaccination, among other things.
This prospective study, which lasted 5 years, found that there were 2-3 times less cases of allergies among unvaccinated people. This correlation persisted even after the authors corrected the results for allergy risk factors (sex of the child, parental sensitization, mother’s education, mother’s smoking during pregnancy, number of siblings, life with animals on the farm, and exclusive breastfeeding till the age of 6 months). However, after the authors corrected for the anthroposophic lifestyle, it turned out that there was no longer a statistically significant difference between the vaccinated and unvaccinated. Despite the fact that the division into anthroposophic, partially anthroposophic and non-anthroposophic lifestyles was based on the subjective assessment of the parents, the authors conclude that there is no link between vaccination and allergies, and some other, unknown component of the anthroposophic lifestyle affects the reduced risk of allergies.
