You will not hear this on the news but those who have been vaccinated, can get measles and also transmit it to others. Bacteria and viruses are smart. They have evolved for thousands of years and vaccination is not going to stop them from adapting and replicating .
“Immunization is also making once-rare or nonexistent genetic variants of pathogens more prevalent, presumably because vaccine-primed antibodies can’t as easily recognize and attack shape-shifters that look different from vaccine strains. And vaccines being developed against some of the world’s wilier pathogens — malaria, HIV, anthrax — are based on strategies that could, according to evolutionary models and lab experiments, encourage pathogens to become even more dangerous.”
As we see the frenzy of measles blame on the “anti-vaxxers”, we need to explore some scientific research that shows a different scenario:
This measles outbreak occurred in an adult population with high 2-dose measles vaccination coverage. The primary patient had documentation of receipt of 3 doses of measles-containing vaccine, one each at ages 1, 2, and 6 years, per the vaccination schedule in Ukraine. Although it is possible that the vaccination record contained an error, the high IgG avidity suggests secondary vaccine failure (2). All patients except one had high measles IgG avidity, which is an indicator of previous vaccination or previous infection. Because all the serum specimens (except that from the primary patient) were collected 2–3 days after the onset of symptoms, the high avidity IgG was assumed to be a result of patients’ previous vaccination.
Although outbreaks of measles among vaccinated populations have been reported worldwide (4–7), most outbreaks in Israel have occurred in unvaccinated or partially vaccinated populations (8,9). Measles transmission from a vaccinated person with documented secondary vaccine failure also has been described in New York City in 2011, including among vaccinated health care providers (4), and in the Marshall Islands (10). Waning of vaccine-induced immunity is a phenomenon that needs to be addressed.
An outbreak of measles occurred in a high school with a documented vaccination level of 98 per cent. Nineteen (70 per cent) of the cases were students who had histories of measles vaccination at 12 months of age or older and are therefore considered vaccine failures.
We investigated a measles outbreak among healthcare workers (HCWs) by assessing laboratory characteristics, measles vaccine effectiveness, and serological correlates for protection.....Eight HCWs were notified as measles cases; 6 were vaccinated with measles vaccine twice, 1 was vaccinated once, and 1 was unvaccinated. All 6 twice-vaccinated cases had high avidity and PRN titers....Among 106 potentially exposed HCWs, the estimated effectiveness of 2 doses of measles vaccine was 52%
An epidemiological investigation was carried out for outbreak of measles in a young adult population of college students from Pune. It is reported that, with increase in overall coverage of vaccination, there is a rise in incidence of measles in vaccinated individuals. The age profile also shifts to higher age groups. Investigation of such outbreaks provides an opportunity to identify high-risk groups, changes in measles epidemiology and weaknesses in the routine immunization programs.
This is the first report of measles transmission from a twice-vaccinated individual with documented secondary vaccine failure. The clinical presentation and laboratory data of the index patient were typical of measles in a naive individual.
There is much evidence that vaccination and not exemptions, or unvaccinated people, are a more accurate reason that measles cases are growing. Adaptation and evolution are scientific mechanisms that vaccination produces and provide a new niche(s) for viruses and bacteria to emerge. The reality is that vaccination has unintended consequences:
Here that mechanism is explained:
“Presumably a vaccine is used because it protects the host against death. This means the fitness cost of virulence—the force selecting against virulence—is relaxed by vaccination. Since there are still fitness benefits of virulence, more aggressive strains will spread in vaccinated populations because they are now less likely to kill the host. Even if vaccination reduces pathogen titers and transmission rates, virulent strains will still produce more transmission stages than less virulent strains. In fact, in an immunized host, they may produce disproportionately more transmission stages if immunity is more effective against less aggressive strains. Consequently, vaccinated individuals create the conditions that favor the spread of intrinsically more virulent parasites”
The MMR vaccine is a triple-virus vaccine. It is a live-attenuated vaccine and this concluding paragraph shows how it can cause both undesirable effects on an individual and also on society:
However many live-attenuated vaccines exhibit reversion to virulence through back-mutation of attenuating mutations, compensatory mutations elsewhere in the genome, recombination or reassortment, or changes in quasispecies diversity. Additionally the combination of multiple live-attenuated strains may result in competition or facilitation between individual vaccine viruses, resulting in undesirable increases in virulence or decreases in immunogenicity. Genetic engineering informed by evolutionary thinking has led to a number of novel approaches to generate live-attenuated virus vaccines that contain substantial safeguards against reversion to virulence and that ameliorate interference among multiple vaccine strains. Finally, vaccines have the potential to shape the evolution of their wild type counterparts in counter-productive ways; at the extreme vaccine-driven eradication of a virus may create an empty niche that promotes the emergence of new viral pathogens....This review can also be used to emphasize the danger of ignoring evolution when deploying live-attenuated vaccine viruses, as, without due safeguards, evolution may reshape the virulence or transmissibility of these agents.
