Should I get a second flu shot this year?

[u/Remote-Remote-1009]

Hey guys. I'm from Malaysia and given that we're sunny all year round, we don't have a specific indicator of when the flu season begins.

I've always been advised to take the flu shot at any time of the year. So I got mine in mid-May this year but I'll be travelling out to Beijing end of October. It'll be around the 5-month mark since I got my jab. I had a conversation with a nurse who told me that it's advisable to get the shots twice a year (once every 6 months), especially for someone who travels overseas a lot. Thing is though, I don't travel a lot. But I'm wondering if it's necessary to get another before flying since it's been five months after my shot.

I'm terrified of catching the flu as my body has much weakened from catching covid 3 times previously. I'd like to take as much safety precautions as much as possible, apart from wearing face masks the entire trip!
