Despite vaccinations, COVID-19 variants, particularly Omicron and its subvariants, continue to evolve and challenge our immunity, leading to increased reinfection rates. Healthcare professionals emphasize the necessity of receiving annual boosters similar to flu shots, as immunity wanes six months post-vaccination. New variants remain more contagious yet typically present milder symptoms. The unpredictability of future variants highlights the ongoing need to monitor and adapt vaccination strategies accordingly, given they can circumvent prior immune responses developed from previous infections or vaccinations.
We're now five years in and still seeing new variants and subvariants of COVID-19, which can mutate into forms that evade the immune system.
The most recent COVID vaccine protects against subvariants that weren't here last year, but it's impossible to predict what we'll see down the line.
