A dose of Covid vaccine to recover? It’s possible. The Ministry of Health gives the green light to the possibility of administering a single dose of anti-Covid vaccine, without booster, to people who have already had an infection than the SarsCov2 virus.
This is what establishes a circular of the General Directorate of Prevention of the Ministry of Health, signed by the General Director Giovanni Rezza, which highlights: “It is possible to consider the administration of a single dose of anti-SarsCoV -2 / Vaccine Covid-19 in subjects with previous infection of Sars-CoV-2 (symptomatic or asymptomatic course) “.
Vaccine, single dose without booster 3 months after infection
However, the circular specifies that the administration of a single dose is possible, “provided that vaccination is carried out at least 3 months after the documented infection and preferably within 6 months of the same “.
But the recommendations, he says, “could be revised if variants characterized by a particular risk of reinfection emerge and spread.”
Covid vaccine and single-dose: beware of these pathologies
The possible administration of a single dose of Covid vaccine to people who have had a SARS-CoV-2 infection “is not meant to be applicable to the subjects who present immunodeficiency conditions, primitive or secondary to pharmacological treatments ”, we read again.
In these people, according to the circular, “given that 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 scheme (double dose for the three currently available vaccines) “.
Covid vaccine, it is important to document the infection.
Since information regarding a previous Sars-CoV-2 infection is collected at the time of vaccination through a self certification template, highlights the circular, “it is recommended to collect, whenever available, documented evidence of infection of Sars-CoV-2. In the absence of this evidence of positivity for the swab – emphasizes the circular – it is recommended that the anamnestic information relative to a previous infection be collected in the most complete and detailed way possible ”.
In addition, “as indicated by the World Health Organization, the performance of serological tests aimed at identifying positive antibody against the virus or another type of test, not recommended for vaccination decision making. Finally, these recommendations could be revised if variants of Sars-CoV-2 arise and spread with a particular risk of reinfection ”.
