Vaccines against covid-19 do not implant brain nanosensors which can be controlled by 4G and 5G

There is a video circulating on WhatsApp suggesting that vaccines against covid-19 have the mission to implant nanosensors in the brain, which allow them to give orders to the body through the 4G and 5G networks. This is FALSE. None of the vaccines against SARS-CoV-2 is designed to introduce microscopic sensors in our nervous system, so it is impossible that if we are vaccinated we will be controlled by mobile networks. 

"The nanosensors implanted in the brain can emit real time data to control centers via 4 and 5G networks and, depending on the received data, such centers could emit signals and orders to such biosensors in our body and brain"

The speaker of the video affirms that these nanosensors are programmed to transmit signals, but the reality is far from this claim. Nanotechnology has long been applied to understand how the brain works and to treat neurological diseases that are difficult to treat because of the nervous system complexity. Ten years ago, for example, this technique was already being used to diagnose brain tumors. Advances in science have made it possible to adapt it to such delicate cases as administering drugs using nanoparticles that manage to cross the blood-brain barrier, a small layer of cells that cover the brain's blood vessels and whose impermeability prevents the exchange of substances between the brain and the blood. 

These techniques, however, do not work through the 4G and 5G networks, which are mobile technologies, the latter more advanced than the former, which facilitate the velocity of navigation increasing the capacity of connection of mobile devices such as smartphones, tablets or laptops. Their design is not related to the function of nanotechnology in the brain. As the World Health Organisation (WHO) explained in February 2020 in relation to the advent of the 5G network and its impact on health, "to date and after much research, no adverse health effects have been causally linked to exposure to wireless technologies”. Furthermore, he stressed that "the radio frequency exposure levels of current technologies cause a negligible temperature increase in the human body".

The fifth generation of mobile networks uses small cells, towers, masts and other transmission systems installed in buildings, which connect with a main network that administers the connections. Its objective is to achieve an ultrarapid connection being able to transmit data using a much lower power.
