The upcoming flu season in Europe may be severe due to low vaccination rates and early signals from countries like Japan and Australia. As of mid-October, flu-like symptoms are increasing, and health experts are monitoring flu activity, particularly in vulnerable populations. Vaccination rates have lagged, raising concerns about the potential severity of the season. The EU aims for 75% vaccination coverage, but many countries fall below 50%. Health officials stress the importance of timely vaccination, especially for high-risk groups.
