The US Centers for Disease Control and Prevention (CDC) is launching a new advertising campaign to address misconceptions about flu shots. The campaign aims to boost confidence in flu vaccines by emphasizing that while they may not prevent individuals from getting sick, they can significantly reduce the severity of the infection, shifting it from "Wild to Mild." The ads target pregnant women and parents of young children, as vaccination rates have declined among these high-risk groups. Despite the belief that flu vaccines should completely prevent illness, experts highlight that they are more effective at preventing severe complications rather than mild disease. The campaign seeks to provide clarity and motivate individuals to get vaccinated, especially those at higher risk.
