Covid Deaths Last Winter: 1,906 Fatalities, 96% 65+, Not Age or the Variant to Blame

A striking figure, yet it mainly conceals a more precise explanation than the mere inevitability of age. Last winter, 1,906 people died of Covid in France, and nine out of ten were over 65. One could conclude that the virus continues to strike the frailest bodies without surprise. Yet, digging a little into public health data reveals another reality, far from common beliefs about age-related vulnerability or the supposed danger of a new variant. What emerges from this analysis concerns a simple, accessible action that is too often neglected.

The numerical tally of winter 2025-2026, examined in detail

Between October 2025 and April 2026, Public Health France recorded 1,906 deaths mentioning Covid-19, out of a total of roughly 213,000 deaths from all causes. This represents 0.9% of the season’s overall mortality, a figure that may seem modest at first glance. The season also included 194 severe cases admitted to intensive care, compared with 326 during the previous winter, marking a notable decline. In long-term care facilities, which house a large share of frail elderly residents, 954 clustered Covid-19 episodes were reported. Taken together, these figures paint a season that was generally milder than the predecessors, yet it did not spare the most vulnerable.

Why age alone does not explain the observed excess mortality

It would be tempting to stop there and conclude that advanced age alone accounts for the 96% of deaths among those over 65. After all, aging is often accompanied by a less reactive immune system and comorbidities that weaken the body. But this explanation, while not false, remains incomplete. Millions of people over 65 pass through each winter without major issues, and birth date alone does not determine the outcome of an infection. Age creates a conducive ground, certainly, but it is not the direct trigger for tipping into severe forms. The real key to interpreting these figures must be sought elsewhere.

The role of variants ruled out by epidemiological data

Another hypothesis often proposed whenever a peak in deaths occurs is the circulation of a more aggressive variant than the predecessors. Yet the epidemiological data from the 2025-2026 season do not support this. The decline in severe cases in intensive care, from 326 to 194, suggests a viral circulation that is comparable to, or even less severe than, before. Nothing indicates that a particularly formidable strain circulated this winter and explained the concentration of mortality among the elderly. The virus, in broad terms, seems to have maintained a relatively stable danger profile. This finding gradually rules out one path and brings to the foreground another, far more discreet one.

The vaccination deficit identified as a determining factor

This is where the numbers become truly telling. Covid-19 vaccination coverage among those aged 65 and over reached only 16.8% during the 2025-2026 campaign, down by about five percentage points from the previous year, a figure Public Health France even considers likely underestimated. For comparison, coverage was still 30.2% at the end of the 2023-2024 campaign. In two seasons, the protective vaccination for the highest-risk groups has thus eroded noticeably. Interestingly, flu vaccination, by contrast, rose to 56.7% among the 65+ group, an increase of three points—the first rise since the pandemic. This contrast between the two trends illustrates a relaxation specifically toward Covid vaccination, perceived by part of the population as less urgent than before.

What the profiles of the deceased reveal

Cross-referencing the profiles of those who died with vaccination coverage data reveals a clear trend: the majority of deaths involve older individuals who were insufficiently protected, rather than well-vaccinated seniors who nonetheless succumbed. In other words, it is not so much age itself that pushed these people toward a fatal outcome, but the absence or the waning of their immune protection gained through vaccination. With vaccination coverage for those over 65 nearly halved in two years, the field was unfortunately conducive to a resurgence of severe forms among the unprotected. This finding shifts attention to a modifiable factor, unlike age, which cannot be bargained with.

Here are the main takeaways from this analysis:

• Age alone does not suffice to explain the excess mortality observed among those over 65
• The circulating variants did not show increased danger this winter
• Covid vaccination coverage fell to 16.8% among seniors, down from 30.2% two years earlier
• The vaccination deficit emerges as the most determinant factor in the observed mortality

The booster dose, a clinical urgency for autumn 2026

The analysis of the 1,906 deaths in winter 2025-2026 demonstrates that the vaccination deficit is indeed the main factor of Covid-related mortality among those over 65, which clinically makes the booster dose essential this autumn 2026. In fact, recent developments confirm that the virus has not disappeared from the radar: emergency department visits for suspected Covid-19 among adults rose by 22% between September 21 and 27, 2026, i.e., 114 additional visits in a single week. Despite this signal, the Health Ministry chose in early October not to advance the vaccination campaign, arguing that overall indicators did not justify such haste. The joint influenza and Covid-19 vaccination campaign nonetheless began on October 13 in metropolitan France, the Antilles, and Guyana, in line with official recommendations. For people over 65, and more broadly for their surroundings, this vaccination window offers a concrete opportunity to correct course after two seasons of declining coverage.

At heart, these figures tell a fairly simple story behind their statistical complexity: protection from vaccination remains for the most fragile groups a far more decisive shield than the age printed on a passport. Booking this booster is therefore not merely an administrative reflex, but a preventive gesture that can concretely tilt the statistics in the right direction.
