Dr. Bregliasko, Is it true that the virus spreads in 5-10 seconds with the delta variant?
«This is an element of the hypothesis that needs to be verified. In fact, the Australian Ministry of Health, during an epidemiological investigation, reconstructed a chain of epidemic infections, searched the index case and identified it as a quick contact on the sidewalk of a shopping center. They were persons who had no connection with each other: but this was only an observation in one case. Situations like this occur when there are super speakers, especially subjects with a high virus load».
How much do vaccines protect us? What about the second heterologous dose?
«The effectiveness of vaccines against delta variant is high: from AstraZeneca to Pfizer, Moderna and Johnson & Johnson, different vaccines are essentially equivalent. We do not have enough information about the heterologous vaccine, and whether it protects us from this variant is not easy to say now: we will have to wait for studies».
Is the new variant more or less aggressive than before?
«This is also difficult to say: at first glance it was said to have had twice as heavy effects, but now we see a different symptom in young people without fever and loss of taste and smell. I have to say that the biggest case history comes from the United Kingdom where many of the victims received the first dose of the vaccine. I would say that the Delta variant as a whole causes us less fear: it will inevitably come to Italy in a clear way, but the vaccine protection we have already received will ensure that the negative effects of the past are not lost. It would be a very civilized coexistence».
