Two meters away at the table without a mask, quarantine also for vaccinated people in case of close contacts with positives, vaccine also for those who have had Covid after 3-6 months of infection but only one dose.
These are some of the new recommendations of Iss and Inail for the containment of the epidemic in the face of the spread of variants.
Following the circulation of variants of the virus, it is emphasized in the document, "it is not indicated to modify the prevention and protection measures based on physical distancing, on the use of masks and on hand hygiene; on the contrary, an application is deemed necessary extremely careful and rigorous of these measures ".
With regard to physical spacing, in particular, "there is no scientific evidence that demonstrates the need for an increase in the safety distance following the appearance of the new viral variants; however, it is believed that one meter remains the minimum distance to be adopted and that it would be It is advisable to increase the physical distance up to two meters, where possible and especially in all situations in which respiratory protection is removed, such as, for example, when consuming drinks and food "
Close contacts of a COVID-19 case can be vaccinated but "they would have to finish quarantine 10-14 days before they can be vaccinated."
Even vaccinated subjects, "albeit with reduced risk, can become infected with SARS-CoV-2 because no vaccine is 100% effective and the immune response to vaccination may vary from subject to subject. Furthermore, the duration of protection does not exist. has yet to be defined. "
The risk of SARS-CoV-2 reinfection, the report emphasizes, was assessed in a multi-center study involving over 6,600 healthcare professionals in the UK.
The results show that "in subjects with previous SARS-CoV-2 infection the likelihood of symptomatic or asymptomatic reinfection is reduced by 83%".
A person, the document explains, "can become infected in the days immediately following vaccination, as the organism requires a minimum time to develop a complete protective immune response. In the majority of the vaccinated population, the first dose of vaccine evokes a initial immune response that confers only partial protection ".
This starts, depending on the type of vaccine, for those with mRNA after about 2 weeks from the first dose, while for the AstraZeneca vaccine protection starts from about 3 weeks after the administration of the first dose.
For all vaccines currently in use in Italy "it is necessary to administer the second dose of vaccine in order to obtain optimal protection" A person, at the time of vaccination, also clarifies the relationship, "may have already become infected with SARS-CoV -2 and being unknowingly in the incubation phase. In these cases, the infection can occur after vaccination and before the development of a complete protective response. "
The Ministry of Health recommends sequencing the positive samples of individuals vaccinated against COVID-19 in order to verify the possible occurrence of a new viral variant infection.
