How comes i didn't get the flu this year?

my brother, mother, cousin, father and Aunty got the flu (live in the same house except my aunt comes and goes), i sat with my mum for ages, was always in close contact with the rest of them, i was in my brothers room for a while, in and out to check on him, so i'm wondering how comes i havn't got it yet? my usual diet is Oats in the morning with honey and raisons with little bit of milk, a sandwich for lunch and wheteva for dinner, sometimes cereal, i also take cod liver oil, and i'm 5 foot 6 or 7 and weigh around 100lbs. Only answer if you have anything constructive to say, i'm not showing off ive been researching before i posted this but couldn't find anything, just asking.

by the way i am female

most likely you are a healthy person and you have a strong system with a little bit of luck good job

people are different
if u have the flu when u r little there are many protective vires in ur body if u have had the flu , ur body reconise it and attacts ur virise very quickly
but some people have less protection on there body and
there body take time to reconise the viruse and it take longer to get better

you dont have to get the flu every year i haven't gotton the flu in like 3 years.

idk maybe your just lucky
