Doha: a revolutionary directed through researchers at Weill Cornell Medicine-Qatar (WCM-Q) revealed critical data on the evolution of the dynamics of immunity opposite to the reinfection of COVVI-19.
The effects highlight a replacement in the evolution strategy of the virus, going from the updated prioritization of the Pre-Microna Era building to an immune escape building in the OMICRON period.
The Examine, published in Nature, carried out through a collaborative association founded in Qatar of six establishments and presented epidemiological analysis at the point of the population in more than 1. 5 million people, who cover the four -year era of the pandemic . The examination revealed that before the OMICRON appearance, herbal immunity provided sustained and physically powerful coverage opposed to reinfection, with an estimated effectiveness of around 80%. However, for other inflamed people after the appearance of the OMICRON variant, this coverage has only remained forged in recently inflamed individuals, temporarily reducing insignificant grades in a year.
“This evolution without stopping and this immune escape makes it difficult to achieve the long -term immunity of the population opposed to the virus,” said Dr. Hiam Firelly, the first of the exam and the assistant teacher of the sciences of the phytness of the population In WCM-Q. “Short -term immunity leads to repeated waves of infection, reflecting models observed with coronavirus without blood and flu. This virus is there to remain and will continue to reinfect us, a little like other existing coronavirus. Regular vaccine updates are essential to renew immunity and protect vulnerable populations, especially the elderly and those who have underlying problems. »
Dr. Mainth Abu-Raddad, the main writer of the examine and professor of phytness sciences of the population on WCM-Q, said: “The virus has shown a remarkable adaptability, which allows persisting in human populations and causing repeated reinfections. Fortunately, these reinfections are almost gentle or asymptomatic. Our exam shows that herbal immunity offers physically powerful and lasting coverage opposite to Covir-19 would be in times of preimage and omicrons, with very few symptoms of decrease. The immediate evolution of the virus had a minimum in this coverage. Although the rodic virus is a component of our lives, it will not constitute the same serious risk as during its first appearance. »
The exam, entitled “Differential coverage opposite to the SARS-COV-2 reinfection, before and after the image”, became imaginable thanks to the financing of the Weill Cornell Medicine-Qatar Biomedical Studies Program. The National Study Group of the COVVI-19 Epidemiology that produced this exam includes, in addition to WCM-Q, Hamad Medical Corporation, of the Ministry of Public Health, the Primary Health Care Care, of the University of Qatar and Cider Medicine .
