Having had it back around Easter....I will vouch that it was for me a 3-star Flu-like experience...ten days of house-rest, some serious coughing, and a minor temperature. If this is the standard, then it wouldn’t matter to me if I had this every 18 months. After two or three bouts....natural immunity would arrive and I’d just accept it.
I red decades ago that the immune system is like a muscle in that, without regular “exercise”, it atrophies. Farm kids were exposed to many more “exercises” than city kids and hence were more immune to hay fever or asthma. Don’t know if that is true but it seems to make some sense. At the age of 69 I have never had the flu, never had mumps, did have measles and chicken pox which were common in my childhood. I am a proponent of tried and true vaccines like polio and dpt but I have taken the flu vaccines once when we had a baby who was very vulnerable to respiratory infections. I am willing to trust my own immune system over this hastily-authorized treatment now pushed by government. If I am banned from any business or activity, so be it. I, and the business, will have to live with it.
