Covid vaccine, reinfecting and transmitting the virus: what we know


May 10, 2021

Is it possible to get reinfected after getting vaccinated? And being unwitting carriers of the virus? To take stock of the coronavirus and the covid vaccine with Adnkronos Salute is Claudio Mastroianni, director of the Department of Infectious Diseases of the Policlinico Umberto I in Rome. To date, over 7.4 million Italians have completed the vaccination cycle. “Once the number of vaccinated people increases, it will be possible, as is already the case in other countries that are ahead of us, to take off the mask outdoors. But until then it is necessary to gradually reopen and keep the epidemiological situation under control in order to be immunized. it involves some benefits, they are safer than the disease, but also responsibility because we have no absolute certainty about some aspects of the immune response “. What do we know about reinfection after getting the vaccine? “It is certain that vaccination protects against Sars-CoV-2 and studies are coming out in which it is shown that the vaccine also protects against transmission but not 100% – replies Mastroianni – By increasing vaccinations and circulating the virus less the possibility of transmission will go down more and more “. Does the protection against Covid work even after the first dose? “For mRna vaccines – specifies the infectious disease specialist – the protection is at 95% after the second dose, but many studies and also the confirmations coming from ‘real life’ tell us that after two weeks from the first dose the protection is already very high “. After the second dose, can you still be an unwitting carrier of the virus? “On this aspect there are no data and it is very rare that a vaccinated subject can reinfect himself or be able to transmit the virus – he clarifies – However, the viral load will be low or very low, the subject asymptomatic and certainly also the contagiousness will be really minimal “. And in this case, do vaccinated people have to swab? “Even those who have already made the recall must still be attentive, if they know they have been in contact with a positive they must swab – he concludes – I give an example, I work in a Covid ward if I realize I have a symptom I will do it immediately a swab or if I had a contact at risk, screening always remains important, vaccinated or not. “” I don’t see how national recovery and resilience plans can be implemented without the involvement of national parliaments. ” Involving the Parliaments “is not just something we ask for”, but it is “essential for the Member States,” Gentiloni said later.
