A motorized ‘spermbot’ has nothing to do with the COVID-19 vaccine

A video circulating on social media states that “nanobot” – which is said to be contained in the Pfizer-BioNTech and Moderna COVID-19 vaccines – “attacks sperm” and changes e DNA of a pregnant egg. The claims presented in this video are false: the COVID-19 vaccine does not contain small computers or robots and will not genetically alter the recipients or their children.

A Facebook post with the video that has been shared more than 1,065 times reads: “You better not get the covid test or that vaccine. I warn you folks. These evil psychopaths have been trying to hurt and depopulate us for a while now. “

Another feather can be seen here.

The clip contains a female voiceover which begins with the warning: “This is what they are hiding from your family. This is that they don’t want you to know. “

She says that the Pfizer-BioNTech and Moderna COVID-19 vaccines, which she calls “nanobytes,” contain “millions and millions of” small robots “, most likely in terms of nanobots (here).

“Now what you look at is a nanobyte attacking sperm. And this is the marrow that goes into the egg, ”says the voice. “Now you got a chip that was inserted into that child with DNA written on it to destroy that child’s DNA”.


As previously explained by Reuters here, the Pfizer-BioNTech COVID-19 vaccine contains “nanoparticles,” a lipid that is between 1 and 100 nanometers in size, but not nanobots or any type of chip or computer. The Moderna vaccine contains lipid nanoparticles (here) but not nanobots.

Reuters has also repeatedly dealt with false claims about the vaccine containing a microchip in the recipient’s body (here, here)


Two of the three vaccines authorized and recommended in the United States to prevent the new coronavirus (here), the Pfizer-BioNTech vaccines and the Moderna COVID-19 vaccines, rely on a new technology called messenger RNA (mRNA).

As explained by the U.S. Centers for Disease Control and Prevention (CDC) here, instead of introducing a weak or inactive virus into our bodies, mRNA vaccines teach our cells how to make proteins , or a piece of protein, to stimulate an immune response. .

Dr. Paul McCray, professor of pediatrics, microbiology and internal medicine at the University of Iowa (here), previously told Reuters via email how a COVID-19 vaccine would use a DNA or RNA vector working.

As with vaccines that use an inactivated (dead) virus, the only change in the host is to stimulate them to make antibodies and T cells that prevent or kill infection with the virus any infectious cells to prevent or reduce disease. depth, ”McCray said.

“This is what happens if you get a viral infection naturally, but the vaccine carries a risk of serious infection out of the equation. ”

Reuters has previously leaked false claims on social media that the COVID-19 vaccine would involve injecting the genetic code of the virus genetically altering the recipient or their children here and there.


The film that has been misrepresented in this claim comes from a laboratory demonstration of the “spermbot,” an artificially “motorized” sperm that may be a means of assisted reproduction. It can be seen here in a video in 2016 by the Chemical Society of America (ACS).

A 2016 paper, published in the journal ACS Nano Letters (here), states that the “spermbot” uses micro-controlled microbes to act as “motors” for transport sperm cells with mobility deficits.

At the time researchers said more studies were needed to achieve successful fertilization with the artificial motor sperms and before it could be confirmed in the human body (here, here).


Attracted. The COVID-19 vaccine does not infect many computers or robots. It will not cause genetic modification of recipients or their children, according to experts. In this clip is a laboratory display of artificially motorized sperm with microhelices controlled by a magnetic field. It is not linked to the COVID-19 vaccine.
