The misinformation on Covid strikes again: the latest episode in chronological order is the refusal of the daughters of a ninety-year-old hospitalized in Rimini to authorize the blood transfusion he needed. The reason for the refusal is the fear that the blood of a vaccinated donor could “transmit RNA”.
The hoaxes about the risks of contracting Covid by donating or receiving blood have been circulating for some time and have been re-launched by well-known personalities, but once again they must be categorically denied.

Donation and transfusion are safe
“Vaccinated people can safely donate and the bags taken from those who are immunized are used in recent months for transfusions without any difference with the others”, reiterated the National Blood Center (Cns), consulted after the statements by Enrico Montesano.
For Gianpietro Briola of the Avis these are “dangerous statements for public health and detrimental to the commitment of the association and donors. Donating blood after receiving the anti Covid vaccine does not involve any risk either for the donor himself or for the donors. patients to transfuse it “.
And underlines, Vincenzo De Angelis director of the CNS. “It is very serious to spread false information on blood donation. There is no difference between the blood of the vaccinated and that of the unvaccinated, both save lives every day, and indeed we hope that more and more donors are immunized, it would be a further sign of progress in the fight against the virus “.
Are vaccines giving birth to the variants of the virus? No and we explain why
To donate, you need to be in good health
Blood can only be donated if you are in good health, reads the information sheet on the Ministry of Health‘s website, so even a simple cold or sore throat, without any connection to the Coronavirus, would cause temporary exclusion.
The precautions in case of donor positivity
People who have tested positive for the swab or who have had close contact with a positive subject are required to observe a period of suspension from the donation, according to the Avis website.
Their readmission takes place subsequently on the basis of the criteria indicated in the circular of the National Blood Center:
Positive asymptomatic subjects must submit certification of negative result of the swab carried out at least 10 days from the appearance of the positivity;
Positive symptomatic subjects must submit certification of negative result of the swab carried out at least 3 days after the disappearance of the symptoms.
Asymptomatic donors who have had close contact with positive subjects will be able to resume donating at the end of the quarantine period of 14 days from the last exposure (in the absence of swab) or 10 days from the last exposure in case of negative result at swab carried out on the tenth day.
The donor who exhibits flu or Covid-19 symptoms in the 14 days following the donation is invited to immediately notify their Avis or the collection unit.
Covid, it is not true that vaccines are unsafe because they are developed quickly

The donation after getting the vaccine
You can donate blood and plasma after a withdrawal period which depends on the type of vaccine you have received.
If it is a vaccine based on inactivated viruses, which does not contain live agents, or a recombinant vaccine (such as those currently available in Italy), it can be donated 48 hours after administration. In case of symptoms such as fever or fatigue following vaccination, it is necessary to wait at least one week after the symptoms have resolved before donating.
If it is a vaccine with attenuated viruses (currently not yet available in Italy) you must wait at least 4 weeks before donating.
Blood donations in decline, fewer and fewer young people

No risk from transfusion
“There is no scientific evidence proving the transfusion transmission of Covid-19. Furthermore, viruses belonging to the same family as Sars and Mers have never been transmitted with blood.” This was explained by Giancarlo Liumbruno, director of the National Blood Center (Cns). As for RNA, the reassurance also comes from Rino Biguzzi, 62, doctor and coordinator of the “blood plasma” program committee of the Ausl Romagna: “The blood undergoes a processing, a minimum amount of plasma is present, but this aspect concerns dozens of vaccinations. It doesn’t make a difference. ” In other words: with the blood of a vaccinated, one does not become vaccinated.
