Developing and maintaining immunity to the new coronavirus involves more than just antibodies.
According to researchers T cells and B cells also offer us long-term protection from the virus.
Business Insider reports that these immune cells can persist at least eight months in recovered COVID-19 patients.
Researchers found that about 90% of patients develop immunity to the coronavirus with T cells, B cells, and antibodies.
A small subsection of participants however developed only some, or none, of them.
Those patients seem to have a weakened immune response and could be susceptible to reinfection quickly.
