For a glimpse into the future of SARS-CoV-2 immunity, scientists at La Jolla Institute for Immunology (LJI) are investigating how the immune system builds its defenses against common cold coronaviruses (CCCs).
According to a new LJI study, published recently in Cell Host & Microbe, adults have stable memory responses of CCC-fighting antibodies and T cells, presumably derived from multiple exposures to CCCs in childhood. Thanks to this immune cell army, CCC infections in adulthood tend to be infrequent and mild.
These findings may be a clue to how immunity can build up against SARS-CoV-2, the virus that causes COVID-19, and the leading researchers think the COVID-19 booster shots available today may be critical for long-term immunity.
