Exposure to the coronavirus that causes the common cold could lead to Existing immunity to Covid-19according to a new study from Rutgers University (NJ, USA).
The study was published in the journal Journal of Clinical Virology Plus, The researchers examined the immune responses of two groups of people from Lagos, Nigeria: health workers at a university hospital and the general public living at five sites.
“In 83% of the people in our study who were exposed to the common cold coronavirus, we found that their T cells cross-reacted with SARS-CoV-2, suggesting the following facts: People who have been exposed to these genetically related coronaviruses have immunity that protects them from future SARS-CoV-2 infectionsBobby Brooke Herrera, assistant professor of global health at the Rutgers Global Health Institute and lead author of the study, said.
The researchers’ findings provide insight into factors that may influence global infectious disease outbreak preparedness and response, such as vaccine development.
Topics discussed in the study include: The link between immunity and The Paradox of High SARS-CoV-2 Infection and Low Mortality in Africa; SARS-CoV-2 seroprevalence was high among health workers and the community in Lagos, suggesting that infection rates may be higher than reported.
They also proposed laboratory techniques to examine the characteristics have immunity to coronavirussuch as antibodies against only the more conserved SARS-CoV-2 nucleocapsid protein compared to antibodies against the SARS-CoV-2 nucleocapsid and spike proteins.
They also include dynamics related to previous SARS-CoV-2 infections and Enhanced antibody response to AstraZeneca vaccine COVID-19; Viral challenge detected by examining T cell responses to SARS-CoV-2 nucleocapsid protein using new whole blood test.
The study’s findings are unique because the data was collected during a critical time during the pandemic. The researchers looked at the antibody and T cell immune responses in people before and after they were vaccinated. Most people have been exposed to SARS-CoV-2 antigens through infection or vaccinationHerrera said.
“However, there are many unknowns “The more we learn about COVID-19, the better we will be able to develop better diagnostics and vaccines for this and other infectious diseases,” explained researcher Herrera.
“We are trying to understand whether T cell based vaccines they do provide cross protection. We know they can cross-recognize other coronaviruses, but we don’t know if cross-recognition really means cross-protection.If so, this may result in New strategy for developing a coronavirus vaccine‘ he warned.
