When i was in the Marines, i had to get the flu nasal mist every November. Within a few days, i always ended up sick. Perhaps that's just the way it works, since the flu vaccine is designed for different strains of the virus every year, so you need to go through the process of building new antibodies every year.

ReplyDeleteRemember that Canadians have less direct sunlight therefore lower vit d levels so weaker immune function overall can be widespread.
