Flu Season
The expected severity of this particular strain isn't as bad toward the elderly but instead will be more severe toward children and young adults.
If you have health issues it's generally recommended to get the vaccine to help you survive a bad flu.
I get a vaccine every year since having the flu twenty five years ago and thinking that I was dying. It hurt and my recovery was slow. Since then I've been hit with colds and possibly the flu but never as severely as that one.
Play it safe and rely on science and a vaccine.
