- The COVID-19 virus is causing worldwide pandemic.
- COVID-19 cases continue to increase.
- Most COVID-19 infections are associated with mild symptoms.
- However, it is unclear whether mild COVID-19 infection can induce immune response which could contribute to immunity.
- Researchers evaluated people who recovered from mild COVID-19 infection to determine if they develop COVID-19 specific immunity.
- Researchers determined that individuals developed COVID-19-specific antibodies, neutralizing plasma, and memory cells that continued for more than 3 months.
- Data also revealed COVID-19-specific IgG memory B cells increased over time.
- Memory T cells have shown potent antiviral function such cytokine secretion.
- Memory T cells are antigen-specific T cells that remain long-term after an infection has been eliminated.
- Memory B cells expressed proteins capable of fighting virus.
- Memory B cells remember the same pathogen for faster antibody production in future infections.
- Mild COVID-19 infection induce memory immune cells that persist and show functions related to antiviral immunity.
