Greco (Cts): “Rapid swabs are a weak element to obtain the Green Pass, guarantees not comparable with vaccine and molecular”

The Green pass obtained through the swab, especially that quick antigenic, is less reliable than that resulting from the vaccination. And in the background you can see the possibility of one revision of the ways in which it is possible to be in possession of a green certification. The statements by Donato Greco, epidemiologist member of Scientific technical committee. In an interview with Corriere della Sera, the epidemiologist explains that “vaccine and swab are not comparable in terms of reliability” and “the time will come when we will have to ask ourselves the problem”. Because a Green pass “based on a weak element such as the antigen test cannot hold up forever”.

To vaccines and the Green pass, he recalls, “we owe the return to a certain normality, the resumption of activities. And also the growth of the GDP ”. But “we do not hide the fact that the Green pass obtained by making the vaccine is not comparable to the Green pass recognized for those who performed a swab – explains Greco – guarantees which are not even remotely comparable. And even among the tampons, the molecular, very more reliable because they examine a fragment of thenucleic acid, and the antigenic ones that detect a part of the spike protein “. The reliability of the unsanitary, he adds, “is not my opinion, it is a fact” and therefore “in the future, with the achievement of 90% of the vaccinated, it could be deleted at least the antigenic one “.

Greco’s words are easily explained with daily data: Sunday, for example, gods 7,569 new cases register only 656 they have been identified through rapid antigen tests. And how many swabs were carried out? Well 445.593 total, of which 340.025 antigenici quick. Therefore 105 thousand molecular they almost returned 7mil cases with an incidence of 6.5 percent. While the incidence of antigenic agents was well below 1%.

Rapid and molecular buffers, the CTS member argues, are “different for specificity and for sensitivity: that is, they can give false negatives and false positives “. And again: the antigen test performed in laboratory it is “safer” than “the one performed at home”. In a moment of recovery of the viral circulation, with the new cases grown of the 41 percent in the last week compared to the previous one, Greco remains calm in view of Christmas: “I expect attach the serene, maintaining the limitations currently in force, observing theobligation to wear masks and distancing “. Although it is “possible” that “some regions pass in yellow already before the end of December “.
