Experts’ findings look promising

A study in Italy shows that the number of deaths from coronavirus decreases after just one shot of the vaccine. The risk of COVID-19 infection and hospitalization is also declining after the first vaccination.

The study was carried out by the Italian National Institute of Health and the Ministry of Health with 13.7 million people vaccinated across the country.

According to the Hong Kong edition of the South China Morning Post, citing Reuters, the results obtained during the study showed that the risk of infection, hospitalization and death gradually decreased during the first two weeks after the first vaccination.

Five weeks after the first dose of Pfizer, Moderna or AstraZeneca vaccine, COVID-19 infection in adults of all ages dropped 80 percent, according to a study released Saturday.

The first such study by a European Union country on the real impact of its immunization campaign was organized by the Italian National Institute of Health (ISS) and the Ministry of Health on 13.7 million people vaccinated nationwide.

Scientists began studying the data from the start of the vaccination campaign in Italy, December 27, 2020, until May 3, 2021.

The analysis showed that the risk of Sars-CoV-2 infection, hospitalization, and death gradually decreased over the first two weeks after the initial vaccination.

“As of the 35th day after the first dose, the number of infections has decreased by 80%, the number of hospitalizations by 90% and the death rate has decreased by 95%,” the Italian National Institute of Health said, indicating that the same pattern is observed as in both men and women, regardless of age.

“This data confirms the effectiveness of the vaccination campaign and the need to quickly reach the population to end the emergency,” said Silvio Brusaferro, president of the Italian National Institute of Health, in a statement.

Among the nearly 14 million people included in the Italian study, 95 percent of those who took Pfizer and Moderna completed their vaccination cycle, while none of those who received AstraZeneca received a second dose.

So far, Italy has followed the manufacturer’s recommendations, giving a second dose of Pfizer three weeks after the first, a second dose of Moderna after a four-week break, and a second dose of AstraZeneca after a 12-week break.

As of Saturday, about 8.3 million Italians, or 14 percent of Italy’s population, have already been fully vaccinated, and about 10 million have received their first vaccine.
