I had my first Moderna *** today. Had a mechanical valve put in 2 weeks ago. I have not tested my INR since getting it, but I am not aware of any data supporting any changes in INR due to the vaccine. I had contemplated waiting a few more weeks, as I am still healing from my surgery and thought that it might not be so good if I get flu like symptoms after the shot, as my wife did, and dealing with that while in recovery. However, CA will open up the vaccine to 16yrs+ in about a week and the floodgates opening might mean that I need to wait several weeks. I had a one time opportunity to get it today and after weighing pros and cons, and checking with my cardiologist, decided to go for it.
So far no symptoms at all.
