In December 2019, it became public that the Bill & Melinda Gates Foundation provided funding for a project that aims to store a person’s vaccination history in a dye pattern, invisible to the naked eye, which is administered under the skin.

This “specialized dye,” which would be administered along with a vaccine, could allow “in-patient” storage of their entire vaccination history without the need to carry a passport or paper.

The researchers suggested that this new injection method would primarily help developing countries, where traditional medical records are rare or non-existent.

However, in the new “COVID” era where most governments are talking about exercising greater vaccination control over the population, this Massachusetts Institute of Technology (MIT) project—largely funded by Gates—takes on new significance, according to The Western Journal.

“Storage, access, and control of medical records is an important topic with many possible approaches,” says Mark Prausnitz, chair of chemical and biomolecular engineering at Georgia Tech, who was not involved in the research.

“This study presents a novel approach where the medical record is stored and controlled by the patient within the patient’s skin in a minimally invasive and elegant way,” he added.

“It’s possible someday that this ‘invisible’ approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided particularly in the developing world,” said the MIT researchers.

The dye uses nanocrystals known as quantum dots. The dots radiate a slightly sub-infrared light that a certain type of smartphone can read.

The material is not injected with a hypodermic syringe but uses a patch with microneedles, 1.5 millimeters long, which dissolve as the dye is administered into the skin.

According to the MIT release, tests using human cadaver skin showed that smartphone cameras could detect quantum dot patterns after up to five years of simulated sun exposure.

The researchers also tested this vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. They found that these rats generated an immune response similar to the response of rats that received a traditional injected polio vaccine.

“This study confirmed that incorporating the vaccine with the dye in the microneedle patches did not affect the efficacy of the vaccine or our ability to detect the dye,” said the researcher Ana Jaklenec.


On July 17, conservative activist Candence Owens shared on twitter the MIT release with the news, with the following text:

That “So interesting” could be interpreted in an ironic sense, as what could go wrong?

There were also other users who echoed the news, which although it is from 2019, spread particularly in the last few days.

The vaccine passport—which is already implemented in almost all of Europe—presents opposition in some countries for fear that it could become a discriminatory tool.

For example, anyone who does not want to be administered the experimental vaccine against the CCP Virus (or COVID-19) will probably not be able to move freely, travel, go to a concert, theater, or wherever he/she likes.

It is not a conspiracy theory; it is something real, which is already being experienced in some places. The same this dye under the skin, it is not a mere “theory” either. It is a kind of “invisible tattoo” that was already tested—coincidentally—at the end of 2019, coinciding with the appearance of the new coronavirus.

What better way to monitor a person’s vaccination simply by scanning their skin?

According to MIT scientist Ana Jaklenec, the dye method could be especially beneficial for tracking vaccines that require multiple doses.
