The vaccination program against covid-19 “substantially” reduced hospitalizations in Scotland by up to 94% four weeks after the first dose, according to a new preliminary study released today.
The study, which has not yet been independently verified, was carried out by scientists from the universities of Edinburgh, Strathclyde, Aberdeen, Glasgow and St. Andrews and the general directorate of public health, Public Health Scotland (PHS), which focused on people who received the vaccines developed by Pfizer and AstraZeneca.
The scientists looked at the numbers of hospitalizations in Scotland among those who received a first dose and compared the data with those who have not yet received the injection.
Thus, they found four weeks after the initial dose, there was a reduction in the risk of hospitalizations for coronavirus by up to 85% with the Pfizer vaccine and 94% with the AstraZeneca vaccine.
For those over 80, one of the priority groups in the immunization plan, there was an overall reduction of 81% in hospitalizations.
“These results are important as we move from expectations to solid evidence of the benefit of vaccines. Across the Scottish population, the results showed a substantial effect in reducing the risk of hospitalization with a single dose of the vaccine, ”said Jim McMenamin, national director of Incidents covid-19 at PHS.
This is one of the first scientific studies on the impact of vaccination in the UK, and the results in England are due to be published today as well.
The United Kingdom is one of the most advanced countries in terms of vaccination, having administered a first dose to more than 17.5 million people, about a third of the adult population in the country.
The British Government’s goal is to complete the immunization of the adult population by the end of July.
The United Kingdom is one of the countries with the highest number of covid-19 deaths, 120,580 confirmed since the beginning of the pandemic, behind only the United States, India, Brazil and Mexico.
The covid-19 pandemic caused at least 2,461,254 deaths worldwide, resulting from more than 111 million cases of infection, according to a report made by the French agency AFP.
In Portugal, 15,962 people died from 797,525 confirmed cases of infection, according to the most recent bulletin from the Directorate-General for Health.
The disease is transmitted by a new coronavirus detected in late December 2019 in Wuhan, a city in central China.
