Autumn settles in, leaves are falling… and viruses are making their return as well. This year, the vaccination campaign against the flu and Covid officially kicks off this Tuesday. And it has one clear objective: to limit epidemic waves and protect the most vulnerable.
Indeed, while Covid was thought to have been pushed to the background, a discreet yet noticeable resurgence is looming in France this fall. In fact, indicators show an upward trend. The XFG variant, nicknamed “Frankenstein” because it originates from a blend of two Omicron lineages, is now responsible for the majority of cases.
So don’t panic, but this resurgence arrives at the strategic moment of launching the joint vaccination campaign against flu and Covid. It is scheduled from October 14, 2025 to January 31, 2026. A campaign that comes at just the right time… provided as many people as possible participate.
What’s fueling this Covid resurgence
The rise in cases observed in France is partly explained by the active circulation of the XFG variant, which would account for roughly 75% of identified cases. This variant combines two Omicron branches, giving it increased transmissibility. But note, this does not yet appear to increase the severity of cases according to available data so far.
Meanwhile, a drop in collective vigilance is playing a role. Many people are less mindful of barrier measures. Additionally, immunity acquired through vaccination or prior infection is beginning to wane for some. This combination — a more transmissible variant + reduced vigilance + waning immune protection — sets the stage for a resurgence.
Vaccines? Our best weapon against spread
The main challenge of this pandemic rebound is its pace. In fact, it begins the moment the vaccination campaign starts. For it to have a meaningful impact, it must be rapid, well-targeted, and well-accepted.
Logistically, the Covid and flu vaccines will be available simultaneously, which simplifies things. We can get vaccinated at the same time (one shot in each arm if needed). The target populations remain the same: those over 65, people with comorbidities, pregnant women, healthcare professionals, etc.
From a communications standpoint, we will need to explain potential side effects and, above all, the benefits. So yes, Covid is back this fall 2025. But this return should not spell panic.
You’ve got it: vaccination remains a useful tool to defeat the spread of the actively circulating XFG variant. If the resurgence is real, signals point to a moderate uptick rather than a tidal wave. To get through this season safely, agree to get vaccinated.
Also remember to continue observing barrier gestures, especially in enclosed spaces. We cannot eradicate the virus, but we can contain it with smart measures!
