Are the Delta and Delta + variants a threat to our vacations? No, as long as you have protected yourself with two doses of the vaccine. the opinion of several experts, in the face of the advance of the new Sars-CoV-2 strains. In Italy the spread of the Delta is estimated at 16.8%: it is of concern in Europe, after the exponential increase in infections in United Kingdom and Portugal, which forced governments to partially restrictive measures. Even outside Europe, there is concern about the variant identified in India in October. In Australia A two-week lockdown was imposed in Sydney.
Protect those over 50
The virus (Delta strain, ed) more transmissible, but also less sensitive to antibodies – writes on Facebook the immunologist of the University of Padua Antonella Viola, taking stock of the variant -. For this reason, those who have received only one dose can not only become infected, but also get sick. So here is now the rush to make calls quickly: it is better to cover people over 50 years of age rather than vaccinating children. We must do the recall without postponing until after the holidays: only after the complete vaccination course can we feel safe. Of the same opinion Francesco Vaia (director of the Spallanzani Institute in Rome): it is important that we leave for the holidays with the second dose of vaccine done. At the same time we must go out to meet people to facilitate them in vaccinations. In Lazio we will do it with centers in tourist resorts, but first we must make people aware of the importance of completing the cycle. In Lombardy it is already possible to change the date of the recall. With the second dose of the vaccine we are able to have protection – the undersecretary of health reiterated Pierpaolo Sileri, interviewed by Radio Me too on Rai Radio 1 -. The infections mainly concern those who are not vaccinated or those who have received only the first dose. Those who receive the second dose and who take the virus, at worst, do not develop severe disease.
Probably the third dose
The surge in cases for the Delta variant, and Delta plus, there will be. We are only behind England. If we are lucky, hopefully, the serious cases will not increase in proportion to the infection – he told al Courier service Fabrizio Pregliasco, medical director of the Galeazzi Institute in Milan -. Those who have already taken the two doses rarely have serious effects. For this reason the invitation, even more intense, to vaccinate everyone with the full cycle. And the Minister of Health Roberto Speranza a Sky Tg24: Completing first and second dose vaccinations is now top priority. Then the scientific community will give us elements of certainty, I hope as soon as possible, so a third dose will most likely be needed. Meanwhile, some Regions are considering anticipating the administration of second doses to counter the possible spread of the Delta variant.
Cases quadrupled
The new strain is advancing rapidly: in one month the cases have quadrupled, going from 4.2% of the total infections (May) to 16.8% in June. We need to continue the vaccination campaign with determination, continue and increase swabs, increase sequencing, said the prime minister Mario Draghi. The data from the Covid Integrated Surveillance System of the Higher Institute of Health indicate that the most widespread variant in Italy is still Alfa (English), with 74.92%, but according to many experts the circulation of the Delta could increase in the coming weeks . For this reason, the Ministry of Health and the Regions insist on the need to continue with the vaccination campaign to immunize as many people as possible with a full cycle, said the Director of Prevention. Gianni Rezza. At the same time, he added, it is important to maintain prudent individual behavior. Although the obligation to wear it outdoors is about to drop, the mask for Minister Speranza e remains an essential tool to keep the virus under control. The coordinator of the Technical Scientific Committee, Franco Locatelli, did not rule out that red areas may be restored in the event of the detection of Delta variant outbreaks.
Tracking and vaccines
The recommendation contained in the new circular of the Ministry of Health to strengthen tracing, considering that the Delta variant is 40% -60% more transmissible than Alfa and may be associated with a higher risk of hospitalizations. As for vaccinations, proceed as soon as possible to administer the second crucial dose to increase protection against Delta variant contagion: There is evidence – the document reads – that those who have received only the first dose of a vaccination that involves the administration of two doses are less protected against infection with the Delta variant than infection with other variants, regardless of type of vaccine administered. An orientation in line with that of the executive director of the European Medicines Agency (EMA), Emer Cooke, for whom the vaccines are also working against the Delta variant, but we must be sure that the second dose is also done.
