T cells triggered by ordinary flu also fend off Covid: Study

The high level of protective immune cells that combat some ordinary colds also makes people less likely to sign Covid-19 in a study.
The researchers found higher T cell level against certain colds in people who did not develop Covid while living with someone who suffered from this disease, according to a study released Monday by Imperial College London.
The previous disease was caused by other Koronavirus related to SARS-COV-2.
These findings, published in the journal Nature Communications, provide further evidence of the effect of T cell protection, the arms of the immune system that gets attention as a stretch of pandemic to the third year and a new variant such as the protection of Omicron vaccine erodes.
“Affected by the SARS-COV-2 virus does not always cause infection, and we want to understand why,” said Rhia Kundu, the main author of the research and researchers at the Imperial’s National Heart and Lung Institute.
“We found that existing T cell level, made by the body when infected with other human coronavirus such as ordinary flu, can protect.” Explanation: T cells standing on the guard against Omicron as an antibody failed.
Scientists analyzed blood samples from 52 people living with someone who had been positively tested for Covid, where half was not infected.
Their conclusion shows the protective role of T cells caused by other Koronavirus for the first time, they said.
Compared to antibodies, T cells tend to survive longer in the body and can kill infected cells, prevent serious illness.
They also tend to attack a broader relevant pathogen range than antibodies, which enable a greater level of cross protection in various viruses or strains, Peter English, former chairman of the Public Health Medical Committee of the British Medical Association, said in a speech published by the British Science Media Center .
Universal vaccinetibodies caused by the Covid vaccine blocking protein spike, the virus used to enter the cell.
These shots tend to lose effectiveness when a surge experiences significant mutations, as it has in the omicron variant.
But T cells made in response to other Koronavirus are targeting internal proteins in SARS-COV-2, said scientists.
A similar approach can help with the development of a universal vaccine that can prevent infection from the current and future variants, the author said.
“Internal protein targeted by the protective T cells that we identify far less,” Kundu Imperial said.
“The new vaccine that includes this conservation, internal protein will cause protective T cell responses to be protected against the variant of the” current and future variants.
There are warnings for findings.
This study was small and 88% of participants were ethnic European white, according to the statement.
The best way for people to protect yourself from Covid still has to be fully vaccinated, including getting a booster dose, Kundu said.
