Subject : Szczepionki DTP zabijaja niemowleta: kolejna praca
============ Forwarded message ============

Kolejna niedawno opublikowana praca naukowa ujawnia, że szczepionki DTP zabijają niemowlęta w biednych krajach afrykańskich – szczególnie dziewczęta. Umieralność żeńskich niemowląt zaszczepionych szczepionkami DTP była kilka razy większa niż niemowląt niezaszczepionych.

Ta sama grupa badaczy wykazała ten efekt poprzednio, ale WHO (która narzuca tym krajom szczepienia) próbowała go zatuszowac i dała te wyniki do analiz innym badaczom. Jednak efekt nie dał się zniwelować. Wszystkim badaczom wyszło to samo, że szczepionki DTP zabijają żenskie niemowlęta w Afryce.

W krajach zachodnich rządy, WHO i producenci szcepionek torpedują przeprowadzenie podobnych badań, widać bardzo się boją ujawnienia podobnych efektów i jego wpływu na zyski z masowych szczepień. Ale dane zebrane w VAERS mówią to samo. W samych tylko USA szczepionki DTP/DTaP zabiły w ciągu 20 lat co najmniej 26 000 dzieci. Dla porównania, dane w EU pokazują, że w Europie dziesiątki tysiecy ludzi zachorowują rocznie na krztusiec, lecz prawie nikt nie umiera z tego powodu.

<span >Abstract

Background Studies from low-income countries have suggested that diphtheria-tetanus-pertussis (DTP) vaccine provided after Bacille Calmette-Guerin (BCG) vaccination may have a negative effect on female survival. The authors examined the effect of DTP in a cohort of low birthweight (LBW) infants.

Methods 2320 LBW newborns were visited at 2, 6 and 12 months of age to assess nutritional and vaccination status. The authors examined survival until the 6-month visit for children who were DTP vaccinated and DTP unvaccinated at the 2-month visit.

Results Two-thirds of the children had received DTP at 2 months and 50 deaths occurred between the 2-month and 6-month visits. DTP vaccinated children had a better anthropometric status for all indices than DTP unvaccinated children. Small mid-upper arm circumference (MUAC) was the strongest predictor of mortality. The death rate ratio (DRR) for DTP vaccinated versus DTP unvaccinated children differed significantly for girls (DRR 2.45; 95% CI 0.93 to 6.45) and boys (DRR 0.53; 95% CI 0.23 to 1.20) (p=0.018, homogeneity test). Adjusting for MUAC, the overall effect for DTP vaccinated children was 2.62 (95% CI 1.34 to 5.09); DRR was 5.68 (95% CI 1.83 to 17.7) for girlsand 1.29 (95% CI 0.56 to 2.97) for boys (p=0.023, homogeneity test). While anthropometric indices were a strong predictor of mortality among boys, there was little or no association for girls.

Conclusion Surprisingly, even though the children with the best nutritional status were vaccinated early, early DTP vaccination was associated with increased mortality for girls.

Introduction

Ten years ago we reported that Bacille Calmette-Guerin (BCG) and diphtheria-tetanus-pertussis (DTP) vaccines surprisingly had opposite effects on child survival in Guinea-Bissau.1 2 BCG was associated with a 45% reduction in mortality over the following 6 months, whereas early DTP was associated with an 84% increase in mortality. The negative effect of DTP was strongest for girls.2 In response, WHO sponsored several groups to reanalyse existing data, but all still reported that DTP had major beneficial effects.3,,8 In contrast, we have continued to find negative effects for DTP for girls in Gambia9, Senegal,10 Ghana,11 Sudan,12 Congo12 and Malawi.13
