Eris, a subvariant of omicron, is gaining attention due to its potential to outpace other variants. The World Health Organization (WHO) warns that Eris can grow and evade immunity, raising concerns.
In the Stockholm Region, Eris has infected over ten percent of COVID-19 cases. Although it's highly contagious, experts suggest it might lead to milder illness for most people. Vaccinated individuals or those previously infected should have good protection, but the Public Health Agency advises booster shots for those over 50 and at-risk groups. An improved vaccine targeting Eris is in development, expected to be available in autumn. Currently, a significant portion of individuals over 65 in the Stockholm Region have received booster shots.
