I had shingles twice in my life before vaccines were available. The new vaccine in better than the first, two shot series. First one, then a second at least 60 days after the first but no more that six months after the first.
Take my word for it, you may get some light side affects, but WAY better than having to deal with shingles.

My wife and I have had both shots with zero side effects.

Same here...waiting for second shot.

I've had shingles twice. After the first time I got the first vaccine, Zostavax, but that didn't keep me from getting them again. Shingles for me was much more itchy than painfull, but the threat of getting it in one or both eyes, a medical emergency due to the potential for it to blind you, is reason enough to get the new vaccine. Zostavax was something like 60% effective whereas the new vaccine, Shingrix, is said to be over 90% effective. Shingrix is two shots with the 2nd administered 2 to 6 months after the first. I had a very mild reaction to the first shot. Sore arm and a bit of the chills the evening of the shot. With the second shot I felt bad for a couple of days. Nothing too bad but I didn't do much but read and sleep for 2 days. That's OK, it's the best indication that your body is reacting properly to the vaccine. Just plan for it. My wife just got the 1st shot last week and felt poorly (flu like) for a couple of days. Your arm will hurt and the arm pain tracks with any other symptoms.

I have had the first shot. Next one coming up soon. Arm was sore from shot more than the flue shot.
No other side effects.

I had both sets of shots and believe me, the sore shoulder is nothing compared to the Shingles rash.

Got both my shots about two years ago. I also had the older version. I remember the first of the two-shot series caused some soreness at the vaccination site. No side effect.

The new dbl shots are 95% effective
