The study emphasizes the importance of regular vaccine updates against COVID-19 due to short-lived immunity resulting in waves of infection similar to influenza. Researchers note that the virus has evolved under different pressures; initially increasing transmissibility, then focusing on evading immunity from prior infections. Although there's some evasion, protection against severe disease remains due to unaffected cellular immunity mechanisms. Continuous monitoring of viral evolution and strategic vaccine updates are vital for maintaining immunity, especially for at-risk populations.
The short-lived immunity leads to repeated waves of infection, mirroring patterns observed with common cold coronaviruses and influenza, highlighting the need for regular vaccine updates.
This virus is here to stay and will continue to reinfect us, much like other common cold coronaviruses, underscoring the importance of maintaining immunity.
