I've had great success with the flu vaccine for the last couple of decades.

Yes, sometimes the vaccine is a bit of a miss, but when it works it's nice not to get sick. I appreciate greatly not getting sick. I'm kinda of whiny baby when I get sick.

In fact, the last time I felt sick was the day after I got the second Moderna vaccine. Felt a little feverish and achy. It lasted one day and was completely gone the next.

However, I've heard of some folks getting pretty sick like vomiting and all that good stuff. But, that beats going to the hospital and dying.
