Expert: Common flu virus could provide immunity against Covid-19

In the search for a universal vaccine Coronavirus diseaseResearchers have found that one of the coronaviruses that causes the common flu can generate immunity to that virus. SARS-CoV-2.

Jose Angel Reguera Nava,researcher Udege People who participated in the study reported that through infection Transgenic mice carrying OC43 virus

one of four causes of the common cold, found to develop defenses Coronavirus disease.

“During the first infection, they develop immunity that protects the mice when they become infected with the virus. SARS-CoV-2 virus“he explained.

Immunity protects individuals from severe disease with less damage to the respiratory tract.

“The results of this experiment suggest less damage to the airways, so Lower chance of getting pneumonia anyone lung damagewhich is very important for diseases Coronavirus disease“.

The findings partly explain why some people experience mild or asymptomatic clinical manifestations when faced with the virus, the researchers added. SARS-CoV-2

.

“Their exposure to OC43 coronavirus helps them develop stronger immunity to Covid-19”explain.

found by Specific segments of proteins that confer immunityHelping a team of scientists design a more precise recipe to develop a universal vaccine that could attack all types of coronaviruses that are circulating, the researchers added.

“Our findings will help scientists design and improve existing vaccines, which we call ‘universal’. This vaccine is not only designed to protect against the SARS-CoV-2 virus, but also against other viruses in the same coronavirus family .”he added.

He explained that the idea of ​​having this type of creature originated from Need to improve effectiveness against SARS-CoV-2 mutationsStrengthen crowd protection and reduce the risk of serious respiratory complications such as pneumonia.

This research has been ongoing since the SARS-CoV-2 virus gained strength around the world in 2020.
