Not sure where you live but we’ve had to get a mandatory flu shot every year since I’ve become an RN. Sure, you can decline it but then you have to mask every day. Yes, fall/winter is atypical flu season but we’ve seen it all year, at anytime for years now. So imo there is no ‘Flu Season’ anymore. People can and do get it anytime all year long. As far as a ‘reduced immune response’ causing people to be more susceptible to the flu, that’s just more fake news Bs. Last time I had the flu? 1998. And I’ve been exposed to flu positive people every year for 12 years now.
