“The delta variant causes a more severe disease course than the previous dominant alpha variant,” Prof. Wojciech Szczeklik, Head of the Department of Intensive Therapy and Anesthesia at the 5th Military Teaching Hospital with Polyclinic in Krakow. The specialist cites the latest research results, which show that unvaccinated people with delta are twice as likely to be hospitalized.
Lancet Infectious Diseases brings you the latest research from Public Health England. Among them, 43,338 people underwent a coronavirus test from March to May 2021. During this period, the Alpha variant was still prevalent, but Delta was already spreading in Great Britain.
Most people have been infected with Alpha, but this has already been discovered after that Delta is more likely to cause more serious illness, requiring a hospital stay. During this period (from March to May), only 2 percent. Respondents were fully vaccinated, 75 percent. However, they did not even receive a dose of the COVID-19 vaccine (others were partially vaccinated).
Public Health England data shows that most patients requiring hospitalization were unvaccinated. However, the delta variant turned out to be more dangerous even among fully vaccinated people.
“Our study indicates that undervaccinations and prevalence of the delta variant pose a greater risk to health care than alpha.”
– warns lead author of the study, Anne Brisanis of the University of Cambridge.
Mileage heavier covid
Although Delta is known to be more contagious, it was not yet certain that it could cause more severe COVID-19, Amber D’Souza, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, said in a statement to NBC News. There is no longer any doubt about that now.
“A pandemic is a test of your imagination. An invisible enemy, an indistinct (mass) infection, no (except in severe cases) amazing symptoms, a quiet death in hospitals, vaccines that work inside the body. Those who understand take shelter, those without imagination take risks.”
– says the COVID-29 expert at the Supreme Medical Council on Twitter, Dr. Paweł Grzesiowski.
Fighting the invisible enemy requires determination, intelligence, and prevention. As with a hurricane or a flood, it cannot be prevented, but thanks to prevention, losses can be minimized. We warn you: the next wave is coming – let’s wear masks, prepare hospitals, let’s get tested and fed https://t.co/42pec1jxz2

Recent research by Public Health England is also convincing that vaccination is worth it. they show it After two doses, a Pfizer preparation from March to May 2021 (when the Alfa variant predominated) protected 96% of hospitalization., and the AstraZeneki vaccine – 92 percent.
Other studies in the US and UK were done later, when the delta type had already spread more, and showed that vaccination was less effective. However, they still provide good protection against hospitalization and death from COVID-19 caused by the delta variant, says BBC News, citing the opinions of British specialists.
We already know that vaccination provides excellent protection against the delta region, which is 99% of that in the UK. COVID-19 infections”
Dr Gavin Dabrira from Public Health England says: He adds that those who have not yet been vaccinated should do so as soon as possible.
