Diabetes: Pneumonia vaccine

I am home today after a day stay in the hospital for pneumonia. For me, it began with pharangitis and a cough for a week. Then, I felt better for a day, then by Sunday, I crashed. My hubby took me to the emergency room that morning. I knew I had pneumonia (I've had it before) but the doctors in the ER were concerned that the spot on my right lung was a blood clot! I had a scary couple of days! Finally, after two CAT scans, x rays, and an ultrasound, they determined that it was just pneumonia.
I met with the diabetes educators while I was there. Actually, I'm a little grateful for the stay. It allowed me to see what correct portions look like, and gave me fool proof practice on carb counting. I couldn't take my metformin while I was there due to the dyes they use for the CAT scans, so I was given insulin.
I still feel tired and a bit short of breath, but much better than I did before. The odd thing is, I had the pneumonia vaccine just last month. The same thing happened to me years ago when I had the flu vaccine...I had the worst flu I have ever had.
Is there anyone here that opts out of the vaccines? Right now, I can't see a viable reason why I should have them.

I have refused those two shots in the past. I was considering reversing that policy (after my recent illness), but your story gives me cause for pause. I would be interested in additional opinions on this.
