Could the SARS-CoV-2 vaccine reawaken previous antibody responses and point the way to a universal coronavirus vaccine? A new analysis of the antibody response to a COVID-19 vaccine suggests the immune system's history with other coronaviruses, including those behind the common cold, shapes the patient's response, according to a study published today in Cell Reports.

A new study from Northern Arizona University and TGEN suggests immune response to COVID-19 vaccines could be shaped by previous coronavirus infections. Key to the study was monitoring spike proteins, which viruses use to enter and infect host cells. Parts of those spike proteins can be shared by different types of the same virus.The study found that COVID-19 vaccines generate

Considering the speculation about whether the SARS-CoV-2 vaccine can reawaken previous antibody responses and pave the way to a universal coronavirus vaccine, new research on a COVID-19 vaccine's antibody response suggests that the immune system's history with other coronaviruses, along with those behind the common cold, influences a patient's response, as per the study published in Cell Reports.

Study: Coronavirus Activates Antibodies From Previous Coronavirus Infections This discovery could help in developing new therapeutic treatments. Individuals who have contracted the coronavirus have been found to rely on antibodies created during infections from earlier coronaviruses to help fight the disease, according to a new study conducted by Northern Arizona University and the Translational Genomics Research Institute (TGen). The research, published in the journal Cell Reports Medicine, noted that the coronavirus isn’t humanity’s first run-in with a coronavirus. In fact, before SAR...

The differences in the pre-existing antibody response identified by this study may possibly explain some differences in how severely COVID-19 disease affects old versus young people.
