Covid, new recommendations: 2 meters away against variants

by admin

More than two meters away from anyone else while eating, drinking or staying without a mask, quarantine even for those who have been vaccinated if they have had close contact with a positive coronavirus case, vaccine in a single dose after a variable period between 3 and 6 months from the disease for those who have already contracted Covid, unless they are immunosuppressed: at that point the times are shortened and the injections increase to two. These are the salient points of the latest recommendations from Inail, ISS, the Ministry of Health and Aifa reported in a document entitled ‘Interim indications on prevention and control measures for SARS-CoV-2 infections of variants and vaccination ‘.

With 2 meter distance variants when you are without a mask

Given the circulation of variants of the SarsCov2 virus, one meter remains the minimum distance to be adopted for the physical spacing but, according to the report, it would be appropriate to increase it “up to two meters, where possible and especially in all situations in which it is removed respiratory protection such as, for example, when consuming drinks and food “. Therefore, where it is still or will be possible to sit down to consume in bars or restaurants, the distances, and therefore the length of the tables, should be further increased.

The vaccine for those who have had Covid

People with a history of SARS-CoV-2 infection confirmed by molecular testing, regardless of whether they have symptomatic COVID-19 or not, “should be vaccinated.” But when and with which serum? “It is possible to consider administering a single dose as long as the vaccination is performed at least 3 months after the infection and within 6 months after the same.” Exceptions are people with immunodeficiency conditions, primary or secondary to drug treatments, who, even if they have had Covid, “must be vaccinated as soon as possible and with a two-dose vaccination course”.

Regarding the safety profile of anti-COVID-19 vaccines, “there seem to be no significant differences between SARS-CoV-2 positive subjects”, who have already had Covid-19, “and negative ones”. However, “some recent reports show expected adverse reactions of a systemic nature, such as fever, chills, weakness, headache, more frequent in subjects with a previous infection than in those who tested seronegative”. Translated: those who have already had Covid, at the time of administering the vaccine, may experience some mild symptoms more frequently than others.

The vaccine for anyone who has had close contact with positive

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.” What is meant by close contact? “High-risk exposure to a probable or confirmed case; this condition is defined, broadly speaking, by the following situations: a person living in the same home as a Covid-19 case, a person who has had direct physical contact with a Covid-19 case (for example the handshake), a person who has had direct contact (face to face) with a Covid-19 case, at a distance of less than 2 meters and at least 15 minutes, a person who she found herself in a closed environment (for example a classroom, a meeting room, the hospital waiting room) with a Covid-19 case in the absence of protective equipment such as the Ffp2 and Ffp3 masks and gloves or medical devices as appropriate as surgical masks “.

Quarantine also for vaccinated after contact with positives

Even those who are vaccinated against Sars-CoV-2 after a high-risk exposure with a Covid case, “must adopt the same preventive indications valid for a person not subjected to vaccination, regardless of the type of vaccine received, the number of doses. and the time elapsed since vaccination “. The vaccine considered ‘close contact’ must observe, as long as always asymptomatic, 10 days of quarantine from the last exposure with a negative antigen or molecular test on the 10th day or 14 days from the last exposure.

But why do you still have to behave like the unvaccinated if you are vaccinated? “COVID-19 vaccination is effective in preventing symptomatic disease, but protection never reaches 100%. Furthermore, it is not yet known whether vaccinated people can still acquire Sars-CoV-2 infection and possibly pass it on to other subjects “, is specified in the report. It is also stressed that some variants “can evade the immune response” given by vaccines. “Preliminary reports suggest a reduced antibody neutralizing activity of biological samples obtained from subjects vaccinated with mRNA vaccines against some variants, such as South African, and a low level of efficacy of the AstraZeneca vaccine in preventing mild or mild disease. moderate in the South African epidemic context “.

The anti-Covid measures for the vaccinated

No “free all”, therefore, not even at work or in the family, for the vaccinated. Every worker, including health workers, “even if he has completed the vaccination cycle, to protect himself, any patients assisted, colleagues, as well as contacts in the family and community, must continue to maintain the same preventive and protective measures. and precaution valid for unvaccinated subjects, in particular observe physical spacing (where possible), wear appropriate respiratory protection, sanitize or wash hands according to established procedures “, reads the document.

“Vaccinated people can get reinfected but risks reduced”

In fact, even vaccinated subjects “can become infected with SARS-CoV-2, albeit with reduced risk, since no vaccine is 100% effective and the immune response to vaccination can vary from subject to subject. Furthermore, the duration protection has not yet been defined “.

A study conducted on over 6,600 healthcare professionals in the UK, cited by Inail in the document just released, showed that in subjects with previous SARS-CoV-2 infection “the duration of the protective effect of the previous infection has a median of 5 months”.
