Had mine last Saturday, been getting them for decades. Never had any reactions. I got the regular shot which contains 4 strains.
My sig other was at the grocery store checking on a product and he noticed the pharmacy had flu shots, so he asked about them. He got the "senior" flu shot that contains 3 strains at a higher dosage. Plus he got a coupon for $5 at the grocery hot bar, you think he had struck gold :) Now with the "senior" flu shot, the pharmacist said it will make you very tired for a couple of hours, and sure enough it did. He's back to normal today.
My parents use to get their flu shots every year even up into their mid-to-late 90's. Not once did they ever have an issue.
But I can understand how you feel about "herd medicine". When I first saw my surgeon she was in a nice cozy townhouse office, just her, her tech and the receptionist. Then she went to a group practice which i didn't really care for, but she was so good I went anyway.... I had a feeling she preferred to be outside the box, and sure enough not long ago she went back to private practice.
Doctors are going from private practice to group practice to cut on overhead, medical equipment, payroll, etc. Plus the cost of medical malpractice insurance is eating up their profits since America is so sue happy.
Just up the street is an urgent care that also take on regular patients. I really like the place as is is so close by as my primary doctor's office is quite a drive. I am seriously thinking of changing over to those doctors.
Our health care system is surely broken.
