“A single dose of vaccine for those recovered from Covid”

AGI – IS It is possible to give a single dose of the vaccine to people who have already had Covid at least three months before, and preferably six months before.

This was established by a circular from the Directorate General for Prevention of the Ministry of Health.

“Given the opinion expressed by the Permanent Group on SARS-Cov-2 infection of the Superior Health Council”, we read, “in accordance with that expressed by Aifa on 23/02/2021, it is represented that it is possible to consider the administration of a single dose of anti-SarsCoV-2 / Covid-19 vaccine in subjects with previous Sars-CoV-2 infection (symptomatic or asymptomatic), provided that the vaccination is performed at least 3 months after the documented infection and preferably within 6 months of the same “.

However, this “is not to be understood as applicable to subjects with immunodeficiency conditions, whether primary or secondary to pharmacological treatments. In these subjects, since the immunological protection conferred by the SARS-CoV-2 infection and its duration are not predictable, it is recommended to continue with the proposed vaccination schedule (double dose for the three vaccines available to date) “.

Since the information relating to a previous SARS-CoV-2 infection is collected at the time of vaccination through a self-certification model, the circular emphasizes, “it is recommended to collect, whenever available, evidence of documented SARS-CoV infection -2.

In the absence of this positive swab evidence, it is recommended that medical history information relating to a previous infection be collected in the most complete and detailed manner possible.

Furthermore, as indicated by the World Health Organization, the execution of serological tests aimed at identifying antibody positivity against the virus or other type of test, is not recommended for the purposes of vaccination decision-making. Finally, these recommendations could be revisited if variants of Sars-CoV-2 with a particular risk of reinfection emerge and spread ”.
