• Awareness of vaccination against Covid-19 is reappearing.

    Enough to feed new fake news.

  • For some, the blood type rh would change on the second injection.

  • The French Blood Establishment immediately denied.

Covid-19 cases started to rise again in early summer, and vaccination awareness campaigns are intensifying.

Now in France, people aged 60 and over can receive their second booster dose.

Enough to bring back false information – of which we no longer count the number – about the famous sting.

Often accused of being the cause of dramatic side effects, or of being transmitted by blood, the vaccine is, this time, suspected of changing the rhesus of our blood group.

"The rhesus + or - changes in the blood of vaccinated guinea pigs", writes a person on different discussion channels.

This message, posted on Twitter, was widely shared.

“The blood of vaccinated people does not clot because their Rhesus has been transformed!

“added a user.

More details on another account: “It is now found that the blood rhesus changes after 2 doses of vaccine.

“Can we really go from a positive rhesus to a negative rhesus because of an injection against Covid-19?

FAKE OFF

Rhesus is the positive or negative symbol placed behind the letters A, B or O of your blood group.

The rhesus system indicates whether or not molecules – called antigens – are present on the surface of our red blood cells.

In the French population, 85% of people are carriers of this antigen and therefore have a blood group +.

The remaining 15% are rhesus negative.

If we follow the reasoning of the Internet users cited above, the various vaccines against Covid-19 would make these antigens disappear, changing a person from rhesus positive to negative.

Even stronger: two bites could cause them to appear and thus give a positive rhesus when it was originally negative.

However, the presence or absence of these different antigens is determined by our genes, so it cannot change naturally during life.

This can only happen with treatments, such as bone marrow transplantation.

The French blood establishment got wind of this rumor and hastened to deny it.

“Obviously, the #Covid-19 vaccine does not change your blood group or your Rhesus… If however you doubt it, come and donate blood with us and we will confirm all this #fakenews.

“I invite anyone who believes in what Astrid [author of the message] says, to come and make a donation to the @EFS_dondesang: No problem, we check the ABO and rhesus groups and we send the donor card to the 2nd donation”, quipped a surfer who claims to be a doctor.

And he's right: two donations are needed to be sure of a person's blood type.

All those who knew theirs before receiving their injections can therefore check: there has been no change since.

“I am on my 15th donation, including 5 since the start of the Covid, and still A +”, also notes a user in the comments.
