Social media users around the world are sharing videos in which people who have been immunized against covid-19 attach coins and other small metal objects to their arms. According to users, the fact of being able to secure objects on the place where the vaccine is applied would prove the existence of a magnetic field contained in the immunizing agent.
Theories abound: from identification microchips and monitoring nanorobots to a fanciful connection to the 5G network that will allow real-time tracking of citizens. The billionaire and philanthropist creator of Microsoft, Bill Gates, would be behind the supposed new technology, believe some netizens.
But is it possible that the vaccine is related to any of these claims? THE Brazil Agency explains.
According to immunologist Renato Kfouri, from the Brazilian Society of Immunizations (SBIm), what actually happens is a wave of disinformation that spreads quickly on social networks.
The doctor informs that there is no magnetic component in the composition of the vaccines, and that it is not physically possible to create a magnetic field in the body when being immunized. “All vaccines available in the world, and the four available here in Brazil, share high safety. They are extremely safe vaccines, unrelated to serious side effects. All of them have excellent efficacy in preventing severe forms of covid-19”, says Kfouri.
The Ministry of Health clarified the Brazil Agency that it is normal for some multidose vaccines – those that come in vials that are used for more than one person – to use thimerosal – a mercury-based preservative that has been used for decades to prevent contamination by bacteria and fungi. The amount, however, is insignificant and does not have the capacity to generate the effects shown in the videos.

But why do vaccines generate symptoms?
In fact, symptoms are caused by the body’s immune response. Upon recognizing the antigen present in the vaccine, the body automatically triggers its natural defenses to fight the presumed enemy.
This means that the molecules present in the vaccine trigger a danger alarm. The body cannot differentiate an active virus from the immunizing particles contained in the vaccine, whether it is based on inactivated virus, encapsulated protein or messenger RNA technology – the three main technologies for manufacturing vaccines against covid-19.
Upon realizing the presence of the “invader”, the body starts a complex cascade of reactions. Various defense molecules are immediately dumped into the immune system. The metabolism speeds up, and the body races so that monocytes – the cells that act as soldiers to defend the body from viruses and bacteria – reach the battlefield as quickly as possible.
“Many common diseases in Brazil and in the world are no longer a public health problem because of the massive vaccination of the population. Possible reactions, such as fever and local pain, can occur after the application of a vaccine, but the benefits of immunization are much greater than the risks of temporary reactions”, informs the Ministry of Health.
The fight usually takes place in the region where the immunizing agent entered the bloodstream, that is, in the arm. The burning, local pain and the sensation of increased temperature indicate where the immune response is being applied.
It is common for post-vaccine symptoms to be identical to those of the disease, since the purpose of the immunizing agent is precisely to simulate a bacterial or viral invasion (in the case of covid-19) to “train” the body’s response against the disease. The answer, therefore, is consistent with the effects that would be caused by the live virus, but without the risk of uncontrolled replication of the invading agent.
Some vaccine technologies, however, generate stronger reactions than others due to the amount of viral material contained in the doses.
Food against covid-19?
According to the Ministry of Health, the severity of the pandemic is proportional to the amount of fake news and disinformation. Another recent rumor opposed by the ministry is the one that deals with foods that would have positive effects on the disease, which is not supported by any research or study so far.
“The population must take even more care with the information they receive and share on their cell phones and social networks, especially those that guarantee a miraculous solution, without scientific evidence. Therefore, it is worth emphasizing that any treatment must be indicated by a medical professional”, warns the folder.
The Ministry of Health also warns that the flu vaccine has absolutely no immunizing effect on covid-19 – misinformation also spread on social networks.
