Harm of HPV vaccine
Latest information and examination of epidemiological studies
Abstract:
According to the latest pharmacovigilance data, the incidence of serious adverse reactions to HPV vaccine is 3.2% per year (3,200 cases per 100,000 person-years). This is similar to the incidence rate of serious adverse events within 1.2 years after the first vaccination (annual rate of 2.8%) reported in randomized controlled trials (RCT) for Cervarix. In Cervarix RCTs, the excess incidence of serious reactions, autoimmune diseases and death after 3.4 years compared with reactions from 1.2 to 3.4 years was respectively calculated to be 4,000 patients, 630 patients and over 100 deaths per 100,000 person-years. These might also occur in Japan. The epidemiological surveys from Europe and North America that Japan’s Ministry of Health, Labour and Welfare (MHLW) used as evidence for safety of the vaccine have flawed methodologies. One study confused prevalence with incidence, and the other two have serious risk of bias attributable to the "healthy vaccinee effect". While there is no evidence yet confirming that HPV vaccination decreases the incidence of and mortality from cervical cancer, assuming that the vaccine could halve cervical cancer mortality, the expected maximum benefit would be 2.0 deaths per 100,000 person-years. Hence, the harm experienced to date is overwhelmingly greater than the benefit expected.
Conclusion:
As the harms of HPV vaccine became well known, many serious adverse reaction cases were reported long after injection including unprecedented “severe reactions”, which were completely new even to specialists in neurology and collagen disease of childhood. Because the risk of autoimmune disease is estimated to be several hundred-times higher and even the excess fatalities higher than the maximum expected preventable cervical cancer death risk by several orders of ten; so, the harms are definitely unacceptable. The MHLW and the manufacturers should admit the causality of the HPV vaccine in serious adverse reactions as soon as possible. HPV vaccine should be withdrawn from the market and all women inoculated with HPV vaccine should be followed up.

SV40 causa cáncer, vacuna contiene SV40, conclusión???
Recent studies have detected simian virus 40 (SV40) DNA in certain human tumors and normal tissues. The significance of human infections by SV40, which was first discovered as a contaminant of poliovirus vaccines used between 1955 and 1963, remains unknown. The occurrence of SV40 infections in unselected hospitalized children was evaluated. Polymerase chain reaction and DNA sequence analyses were done on archival tissue specimens from patients positive for SV40 neutralizing antibody. SV40 DNA was identified in samples from 4 of 20 children (1 Wilms' tumor, 3 transplanted kidney samples). Sequence variation among SV40 regulatory regions ruled out laboratory contamination of specimens. This study shows the presence of SV40 infections in pediatric patients born after 1982.
SV40 is significantly associated with some types of non-Hodgkin lymphoma. These results add lymphomas to the types of human cancers associated with SV40.
Intracerebral and subcutaneous injection into newborn hamsters of vacuolating virus, SV40, grown in renal cell cultures of grivet monkey resulted in single or multiple fibrosarcomas at site of injection which were histologically of varying degree of malignancy. These occurred 3 1/2 to 8 months post-inoculation and in both sexes.
#2"Poliovirus vaccine produced in 1954 contained a variant of SV40 that can be distinguished from common laboratory strains. This viral variant has been found in three non-Hodgkin’s lymphoma patients"
Tampoco se puede demostrar que la vacuna no produce cáncer, pero para qué asegurarse si total son unos pocos.
Pregunta. Según los siguientes datos estadísticos recogidos en Estados Unidos desde el año 1900, la incidencia de ciertas enfermedades se ha ido reduciendo progresivamente incluso antes del inicio de las campañas de vacunación. Al inicio de estas no parece discernirse una reducción drástica del número de casos como se aprecia en las gráficas de los siguientes documentos:

Over the last 100 years, North America and Europe have experienced a substantial decline in mortality and an increase in life expectancy. The "theory of epidemiologic transition" attributes these trends to the transition from an "age of pestilence and famine," in which the mortality pattern was dominated by high rates of infectious disease deaths, especially in the young, to the current "age of degenerative and man-made diseases" in which mortality from chronic diseases predominates.

Diphtheria Toxoid - Characteristics
Beginning in the early 1900s, prophylaxis was attempted with toxin–antitoxin mixtures. Toxoid was developed around 1921 but was not widely used until the early 1930s. It was incorporated with tetanus toxoid and pertussis vaccine and became routinely used in the 1940s.
Según estas gráficas que recogen datos desde el año 1900, la incidencia de enfermedades como la difteria, tos ferina, rubeola y poliomelitis ha ido cayendo drásticamente independientemente de la introducción de la correspondiente vacuna. La vacuna de la difteria se comenzó a aplicar masivamente en 1930 y la triple vírica desde los años 40. Como se ve en las gráficas, la incidencia de estas enfermedades ya había decaído.
¿Podrían existir otras causas aparte de la vacunación que contribuyeran a la reducción en la incidencia de estas enfermedades? No digo que las vacunas no hagan su papel, pero la situación actual podría deberse a la suma de muchos factores.
Preguntas. ¿Es cierto que muchas vacunas no proporcionan inmunidad a lo largo de todo el periodo de vida del individuo? ¿Sería necesario revacunar en la etapa adulta? Si es así, ¿se podría considerar a los adultos de más de 30-35 años vulnerables a las enfermedades?
Tetanus-specific antibodies decreased rapidly, with an estimated half-life of 11 years (95% CI, 10 to 14; P<0.001), which is similar to the decrease shown in a model reported more than 40 years ago.
An analysis of diphtheria-specific antibodies indicated an estimated half-life of 19 years (95% CI, 14 to 33; P<0.001). These results suggest that antibody maintenance is greatly influenced by the nature of the antigen, with these proteins eliciting quantitatively shorter antibody responses than those observed after viral infection.
Sanitation and Hygiene
The 19th century shift in population from country to city that accompanied industrialization and immigration led to overcrowding in poor housing served by inadequate or nonexistent public water supplies and waste-disposal systems. These conditions resulted in repeated outbreaks of cholera, dysentery, TB, typhoid fever, influenza, yellow fever, and malaria. By 1900, however, the incidence of many of these diseases had begun to decline because of public health improvements, implementation of which continued into the 20th century. Local, state, and federal efforts to improve sanitation and hygiene reinforced the concept of collective “public health” action (e.g., to prevent infection by providing clean drinking water).
The decline of mortality in industrialized countries
There is a long history of human experience demonstrating that most disease need not occur. In Europe there was a decline in mortality in the latter nineteenth and early twentieth centuries from infectious diseases such as gastroenteritis, measles, whooping cough, diphtheria, tuberculosis, puerperal sepsis, and pneumonia, long before the advent of any effective specific therapy [6] Figure 1 (see FIG. 1. Death rates of children under 15 from whooping cough in England and Wales (Source: ref. 7)) and figure 2 (seeFIG. 2. Death rates of children under 15 from measles in England and Wales (Source: ref. 7)) show the dramatic fall in mortality from whooping cough and measles in England and Wales from 1850 to 1960, despite the lack of any therapy for this disease until the recent development of vaccines [7]. In the 1960s before the use of a measles vaccine nearly every child in both industrialized and developing countries contracted measles; yet in the industrialized countries medical treatment was rarely required and measles was not a significant cause of death. In the developing countries, however, measles mortality rates were 100-400 times higher.
Figure 3 (see FIG. 3. Death rates from respiratory tuberculosis in England and Wales (Source: ref. 7)) shows the fall in tuberculosis in England and Wales before BCG or therapies such as isoniazid and streptomycin were available. Similar declines were observed for the other common infectious diseases. McKeown concludes that improvement in food supplies and nutrition is the only reasonable explanation for these declines in mortality. Similar trends are occurring in developing countries today in areas in which some nutritional improvement has occurred despite little or no access to medical services.
