Scientists were surprised when they learned that individuals with a deficit in antibody production recovered from measles just as well as normal antibody producers. […] Therefore the antibody part of immunity is not at all necessary for the natural recovery from measles (p 364).

Whooping cough (also known as pertussis or 100-day cough) is a highly contagious bacterial disease [with] weeks of severe coughing fits. Following a fit of coughing, a high-pitched whoop sound or gasp may occur as the person breathes in. The coughing may last for 10 or more weeks, hence the phrase ‘100-day cough’. The time between infection and the onset of symptoms is usually seven to ten days. Disease may occur in those who have been vaccinated, but symptoms are typically milder [my emphasis].b) Use of gamma globulin (passive antibody) as a treatment for measles to eliminate rashes. This, however, is no longer in use since 1968. A study from 1967 revealed that the vaccine could cause pneumonia as well as encephalopathy (p 347).

Wrong About Polio: A Review of Suzanne Humphries, MD and Roman Bystrianyk’s “Dissolving Illusions” Part 1 (the long version) The response to poliovirus infection is highly variable and has been categorized on the basis of the severity of clinical presentation. When Silfverdale evaluated thousands of vaccinated and unvaccinated breastfed and non-breastfed children looking at the risk of measles, breastfeeding had a far larger impact on measles risk than vaccinating. (p 389)

So, Humphries displays a callous disregard for the significant number of cases with long-term paralysis and, based on her use of the Brown paper, her credibility is highly questionable! Whereas chronic carriers constitute the reservoir of S. Typhi, the maintenance of a high incidence of typhoid fever requires conditions that permit amplified transmission of S. Typhi to susceptible persons. Usually this involves fecal contamination of water sources consumed by large numbers of persons. In the later 19 th and early 20 th centuries, it was demonstrated in Europe and the United States that treatment of municipal water supplied caused the incidence of typhoid fever to plummet, despite the continued existence in the population of large numbers of carriers. Over one to two decades this led to the near-elimination of typhoid fever from many area (Levine, 2018, p. 1142). The risk of disease can be reduced by preventing mosquito bites through the use of mosquito nets and insect repellents, or with mosquito control measures such as spraying insecticides and draining standing water. Several medications are available to prevent malaria in travellers to areas where the disease is common. Firstly establishing the historical record of abysmal sanitation and living conditions at the turn of the century, and secondly reviewing the mortality data from infectious disease in the public record, Dr Suzanne Humphries makes a compelling argument that infectious disease was conquered by improved sanitation and nutrition, and not by vaccination programs which were either ineffective, or actually increased the mortality. To prevent interference from latent transplacental antibodies, the measles vaccine is only given from 9 months onward. Passive antibodies decline before that age so that babies can form a successful immune response to the virus. Any hypothetical risk factors outlined in the 1985 study above are thus nullified.
