After the United Kingdom, Italy also fears the Delta variant. The coronavirus mutation already known as “Indian”, 60% more contagious than the English one (which has long been dominant in our country), agitates experts and authorities, especially for its ability to reinfect even those who are already vaccinated.

Pregliasco: “The Delta variant is among us, but the numbers are underestimated”

Delta variant arrived in Sicily, 10 positive migrants landed in Lampedusa

OUTBREAKS. The outbreak in a gym in Milan, with one of the 10 positives who was infected with Delta despite having already received the double dose of the vaccine, is not the only one to worry. In Lombardy there have been 81 cases since April (with a decrease in June compared to May), while in the south of Sardinia 12 infected with Delta have already been identified. In Puglia, on the other hand, 25 cases have been traced, with two clusters in the province of Brindisi: “It worries us a lot because it could be less sensitive to vaccines: we risk not having herd immunity in October,” explained the Apulian governor Emiliano.

UNDERESTIMATED. The real problem of the Delta variant is its difficult identification: the symptoms similar to a common cold (headache and sore throat and runny nose), different from the common symptoms of Covid, make it even more difficult to flush out. And to understand how widespread it really is, new weapons are needed, from new criteria for analyzing swabs to greater sequencing. Currently, according to the ISS, its incidence on the total of cases is less than 1%, but it is very likely that it is a highly underestimated figure.

I STUDY. The most effective weapon for now remains that of double avaccination. According to a study published in the Lancet, Pfizer’s complete vaccination course protects against Delta variant infection at 79%, that of AstraZeneca at 60%.

MIX VACCINES. Meanwhile, the Aifa has given the green light to the “heterologous” vaccination in the under 60s who have already received a first dose of AstraZeneca, and who will be able to receive the second dose of Pfizer or Moderna: according to the Cts of the drug agency, the mix of vaccines leads to “a significant enhancement of the antibody response”. Vaccination crossing, assured Minister Speranza, “is something that Germany has been doing for two months”. The Regions adapt, after the initial skepticism: even Campania has now banned AstraZeneca and Johnson & Johnson for under 60s and from today will start the booster with mRna vaccines for those who had had the first dose of AZ.
