In middle age I had the flu for seven consecutive years, and serious

few mild ones.
Effectiveness varies from year to year, as they have to guess months
in advance which strains will dominate in the next flu season. But
the vaccine is never entirely ineffective. Such weak infections as I
have had in recent years came when the guess was a poor one.
