Interesting regarding your parents. My 69 year old father-in-law, also in Texas, had his first shot today.
My parents, same age, are many many weeks away in their county in Montana.
The discrepancy is frustrating.
I live in Texas and many people who are 70+ or have serious health issues have gotten the first shot, at least among the people I speak with. May be different in different areas.
My parents are 75+ and live in Nebraska. They've been told that it may not be until March or April. However, my friend's parents still live in the small town in Nebraska where I grew up, and they've received both doses. I can't figure it out.
