One in Four Vaccinated Children in Chinese City Got Measles

One in Four Vaccinated Children in Chinese City Got Measles

Story Highlights

  • A new study shows that despite a measles vaccination rate of more than 97 percent, over a quarter of vaccinated children in Tianjin, China still became infected with measles.
  • Even with two or more doses of measles vaccine, 8.5 percent of cases in the surveillance dataset and 26 percent in the case series dataset contracted measles.
  • The results of the study calls into question the ability of measles vaccines to create herd immunity.

A recent study published in the journal Vaccine revealed that, despite having a vaccination coverage rate of over 97 percent with two or more doses of measles containing vaccine (MCV), 8.5 percent of cases in the surveillance dataset and 26 percent in the case series dataset of vaccinated children in Tianjin, China still became infected with measles.1

Despite high measles vaccination coverage, wild-type measles continues to cause large epidemics in China. The reported vaccination coverage for the last decade in China has been above 95 percent, which is said by public health officials to be the critical vaccination rate for herd immunity and measles eradication, yet measles continues to cause large epidemics every year among highly vaccinated child populations.2

According to the new study, Edmonston-derived vaccines strains are the most commonly used MCVs (usually measles-mumps-rubella MMR vaccine) in the United States and Europe. China uses a vaccine from a locally-isolated measles strain, the Shanghai (or Hu-) 191 strain, which has shown to have comparable safety and immunogenicity to the Edmonston-derived vaccine.1

In China, children receive MCV at eight months old, 18-24 months old and, in some large urban areas including Beijing, Tianjin and Shanghai, a third dose is given at 4-6 years of age. The vaccination coverage is high among children (over 97 percent for the 1st and 2nd dose in Tianjin).1

Vaccine effectiveness of a single MCV dose given in China has ranged from 85 percent when administered at nine months old to 90-95 percent when the second dose is given at 12 months old.1

Public health officials in China are concerned about measles outbreaks occurring in people who have received multiple doses of measles vaccine.1

Vaccine Failure?

 Two datasets were used in this study. The surveillance dataset contained data for 2,945 measles cases from 2009 to 2013 and the case series dataset contained 500 measles cases from 2011 to 2015.1

This study revealed that within a small subset of identified measles cases in Tianjin, there is a high burden of measles among those who have been vaccinated. It revealed that over a quarter of cases of measles diagnosed in individuals living in Tianjin had received one dose of measles vaccine prior to contracting the disease.1

Time-to-event analysis also showed that those with two doses or more of MCV had significantly delayed onset of wild type measles, though the onset of measles for those who received only one dose MCV was similar to those who were unvaccinated. This evidence suggests that one dose of measles vaccine does not provide protection against infection and perhaps the dose administered at eight months of age, one of the earliest suggested dose times in the world for MCV, may indeed have a reduced immune response or no immune response at all.1

Perhaps the most interesting finding in this study is that 8.5 percent of cases in the surveillance dataset and 26 percent in the case series dataset contracted measles, despite two or more doses of MCV. As a result, the authors of the study call for a vaccine effectiveness study to examine the reasons as to why fully vaccinated children are still contracting measles.1

Findings Raise Questions Regarding “Herd Immunity”

Scientists and public health officials today claim that 95 percent of the population must be vaccinated to stop measles from spreading altogether.3 This concept is known as vaccine acquired “herd immunity” or “community immunity,” which is theoretically achieved when a certain percentage of the population is vaccinated, thus preventing transmission of infection. The original theory of herd immunity had nothing to do with vaccination but was reportedly achieved when a certain percentage of humans or animals in a population experienced the natural disease and acquired natural immunity.4 5

This study raises questions regarding the current theory of vaccine acquired herd immunity. If more than 97 percent of the population in Tianjin has been vaccinated with the MCV, yet measles outbreaks have continued to occur, it highlights the fact that a vaccination rate of almost 100 percent does not necessarily result in herd immunity—at least with current measles vaccines.

Moreover, this study calls into question the effectiveness of booster shots. Since 8.5 percent of cases in the surveillance dataset and 26 percent in the case series dataset got infected with measles after getting two or more doses of MCV, this suggests that the measles vaccine is failing to give long-term protection against infection and transmission.

While this study has limitations, it is a good starting point to begin asking serious questions about vaccination and whether the theory of herd immunity is a scientific fact or a myth.

    Good luck protecting your children in 2019.
    Most health (or SICK) agencies are vigorously pushing vaccines of suspect efficacy.

    Its’ amazing in this modern era where we can send missions to the moon and
    admit that we are not the only inhabited planet, that we are naiive enough to believe
    that we need an injection of toxins to be healthy. Not only that but multiple injections
    of multiple different and unnecessary toxins. I can only conclude that the world
    ‘leaders’ either actually believe the lies, or, they have an agenda to depopulate their
    countries.

    We know that 8 months and even 18 months are too soon for an infant to develop immunity from shots. This report demonstrates this.

    I have yet to see a scientific study or valid peer-reviewed article for “herd immunity” – what I have seen is hypothesized projections and inferences that are far from science. It’s not surprising that they don’t stand up to any valid testing.

    In addition, the one piece of data that explains everything is the rate of infection from vaccine-strain virus. Yes, the MMR is making those who receive it infectious carriers.

    Two kinds of possibilities for infection – live virus contracted out in the “wild” and vaccine-strain – “attenuated” virus received via the vaccine itself. It has already been amply proven in Canada and other places that these two possibilities are present with MMR.

    So what’s missing in this picture – it might be noted in the study but just not in this article – is the rate of flu symptoms caused by the vaccines. A second injection could be a potential cause of an increased rate of vaccine-strain-infection.

    I’m not a doctor or researcher – just repeating what I’ve read recently and possibly butchering the details.

    Killing two birds with one stone. Possible side effects of depopulation and first and foremost making Bookoo Bucks for Big Pharma.

    Antibody responses among children born to vaccinated mothers were reduced based on earlier administration of their first measles vaccine dose at 12 years old and under vs at 15 months months of age and older. Negative effects of earlier age at first measles vaccine dose also persisted after the second dose, increasing the risk of reduced antibody responses and secondary vaccine failure among successive birth cohorts systematically initiated to measles vaccination younger than 15 months of age In China, children receive the first measles vaccine at eight months old. Note that the CDC schedule also recommends 2-dose series at 12–15 months, 4–6 years. The CDC also says MMR can be given to children as young as 6 months of age who are at high risk of exposure such as during international travel or a community outbreak. Studies are showing that an attempt to boost antibody titers through revaccination boosters do not result in a sustainable increase of measles virus antibody titers.

    Note also that mutations of measles virus circulating genotypes B3, D4, D8, and H1 all are becoming less able to be neutralized by antibodies, causing a rise in measles outbreaks and puts even those with natural immunity at risk. In one study, measles antibody resistant subgenotype D4.2 MeVs were isolated predominantly in France and Great Britain, countries with higher vaccine coverage rates which suggest that an intermediary level of vaccine coverage provides an environment more prone to driving the adaptive mutations. http://bit.ly/2HuYFhO

    Why isn’t the original study cited under references? When reposting an article like this, many people do want to set the original study. It’s frustrating to have to try to track it down.

      Many times doing your own research and tracking things down actually is good because you find other little gems along the way.
