I checked the figures established by local health authorities in a number of countries in Europe regarding flu related deaths; they are roughly the same as in the US in proportion of the number of inhabitants in those countries: 4 000 to 12 000 per year depending on the severity of the flu in the UK, roughly the same in France and Germany.
These are rough estimates but they give an order of magnitude; indeed, they are not based on confirmed cases, (based on proper identification of the strain of virus involved in those deaths). Does that make per se these statistics invalid? Certainly not: huge numbers of people die each year of diseases like malaria without proper identification of the infectious agent involved; does that means these deaths should not be counted in the stats?
Opposition to vaccination is one thing, denial of the grave even lethal consequences the seasonal flu can have on weak people's health is another. I personnally know of two elderly members of my family who died from the flu, one of them being my father who died from a pneumonia that started as a flu.
