Influenza, experts warn: vaccines essential for the elderly and for keeping hospitals running
From emergency room doctors to the Istituto Superiore di Sanità the appeal to also protect oneself from Covid-19, especially if one is over 65 or frail, to protect one's health and to avert the risk of overcrowding of facilities

With the winter season approaching, the experts' appeals to vaccinate are multiplying: they are directed in particular at the elderly and the frail, who are called upon to get their flu and Covid-19 booster vaccinations, not least because the coronavirus has reared its head again with the Stratus variant, which, by circumventing the immunity guaranteed by previous infections or vaccinations, risks impacting the most vulnerable. A growing chorus of indications that counterbalance the latest data from the Ministry of Health, according to which only 52% of the over-65s were vaccinated in the last flu season, still down on the previous year and a long way from the minimum target of 75% coverage. Let alone the 95% set as the ideal goal.
The appeals to protect oneself come from the Istituto Superiore di Sanità (Iss) - which has just published the data of the Sari Integrated Surveillance Report (on severe acute respiratory infections) - and from the Simeu Scientific Emergency Society. Concerned not only about the health of Italians but also about the resilience of hospitals in the face of a flu wave that, if the trends recorded in Australia are respected, could prove particularly aggressive.
Previous Australia
.Experience teaches or at least should guide one in making choices: look at what is happening in Australia Fabrizio Pregliasco of the University of Milan. 'In the other hemisphere,' he explains, 'two immuno-evasive flu virus variants with a wide spreading capacity (A/H3N2 and B/Victoria) are circulating and are expected here too. What will happen will also depend on the weather pattern: if the winter is harsh with low temperatures, the flu will be heavy, if, on the other hand, there are temperature swings, the other respiratory viruses - parainfluenzal, adenovirus, and others - will make themselves felt, which are less heavy from a clinical point of view. It is a fact that, in addition to influenza, the impact on the season is also determined by other viruses, first and foremost the respiratory syncytial virus, well known for its effects on young children in whom it causes bronchiolitis but which causes flu-like forms in adults and the elderly'.
Iss data
Meanwhile, the Iss's latest Sari report, relating to last season, certifies a number of 601 people admitted to intensive care with 134 deaths. Cases that, it must be said, are down from the 820 of the 2023-2024 season and significantly lower than the 965 recorded for 2018-2019, just before Covid.
Sari surveillance is based on reports from hospitals of all cases of severe acute respiratory infections and acute respiratory distress syndromes (ARDS), admitted to intensive care units and undergoing Ecmo (extracorporeal membrane oxygenation) and in which the presence of an influenza virus type/subtype has been confirmed.
