Complete coronavirus vaccination significantly reduces not only the risk of infection but also the chance of the disease progressing to a long Covid-19 with many months of symptoms, according to a new British scientific study.
The study shows that in the minority of those infected with the virus, even though they have received both doses of the vaccine, the risk of developing prolonged symptoms of the so-called "long-term Covid-19- - for more than a month - is reduced by half, ie by 50%, in relation to the chance of the unvaccinated to get sick for a long time.
Most people get sick with Covid-19, have recovered within four weeks at most, but some continue to have one or more symptoms even for many months after the initial infection, which can happen even in patients who have had mild symptoms.
Scientists at the British College London (King's), led by Dr Claire Steves, published in the medical journal The Lancer Infectious Diseases, according to the BBC, analyzed data collected from the British online application Zoe Covid Study ”, which allows patients to record their own symptoms and duration, the tests they have done, as well as their vaccinations. Between December 2020 and July 2021, the app gathered data on more than 1,2 million people who took a single dose and nearly one million on those who took two doses of vaccine.
It was found that only 0,2% reported how they became infected with the coronavirus after they were fully vaccinated, while almost 0,5% became infected after a single dose of the vaccine they had received. From those fully vaccinated with Covid-19, 5% showed long Covid-19 with a duration of more than one month, against a corresponding percentage of 11%, ie at least twice, among the unvaccinated.
People over the age of 60, especially those with underlying problems such as obesity, heart disease, kidney disease, pneumonia, etc., as well as those who live in low-income and densely populated areas are more likely to have a "breakthrough" infection (as the vaccine is called internationally). , especially if they have taken a single dose.
"The good news is that, as our research has found, dual vaccination significantly reduces the risk of contracting the virus, but also that, in the event of infection, it prevents long-term symptoms," Steves said.
The study also shows that the risk of a fully vaccinated person being hospitalized for coronavirus is reduced by about 70% compared to an unvaccinated person. Even fully vaccinated people who become infected are almost twice as likely (94%) as unvaccinated to be asymptomatic.
