No, vaccines do not make our bodies magnetise
A series of internet users have recorded them affirming that an injection against covid-19 has magnetised the arm, while they put a series of metallic objects in their shoulder that apparently stick.
You have sent us two videos in which different people affirm to have suffered an arm magnetisation after receiving the vaccine. This is FALSE. Vaccines do not have the capacity to magnetise the arm or cause metal objects to stick to it.
"I did not want to get vaccinated but, after so much insistence, I said: “Well, I am going to stop with these things”. And it turns out that I don’t know what they put me in, as you can see, a coin is stuck, a small hook… and a magnet. My whole arm is magnetised, I look like the bionic woman".
This week the message that vaccines magnetise the arm has viralised in different formats. A series of internet users —among them, the main character of one of the videos that you have sent us introduces herself as the “bionic woman”— have recorded them affirming that an injection against covid-19 has magnetised the arm, while they put a series of metallic objects in their shoulder that apparently stick.
Covid-19’s vaccine is not able to produce such an effect because in its composition, as we have already explained, no heavy metals exist. At most, CoronaVac, Covaxin and Epivac, injections contain aluminium salts, which have functioned as adjuvants since the 1970s. Aluminium also functions as a vaccine packaging compound. "Based on scientific facts, none of the covid-19 vaccines contain metals that can be magnetic. Other vaccines do contain small and safe amounts of aluminium, which acts as an adjuvant, but aluminium does not even have magnetic properties", Rebeca Santano, a researcher at the Institute for Global Health (ISGlobal, in Catalan) in Barcelona, points out to Verificat.
Surface tension
To the fact that vaccines could not be able by themselves to magnetise the arm, the scientist adds that “natural oils present in the skin or even moisturising cream can generate a surface tension making slight or small objects like magnets keping stuck to it”.
Being an anonymous user whose identity is unknown, it has not been possible to prove she really received the vaccine. In any case, several verification agencies from the International Fact-Checking Network as Verificat, such as Reuters, Newtral or Politifact, have already insisted that it is impossible for vaccines to cause this effect.
