Shingles vaccine (the new Shingrix) experiences?

Fiberman

My post-polio wife has concerns about getting the new two-injection Shingrix vaccine, yet the disease can be very serious. Questions:

1. What has your physician advised?

2. If you received the vaccine, did you have any unusually servere adverse effects from either or both injections.

I've found little guidance on the Web except a small survey that found the older Zostavax (less effective) was generally safe for PPS.

Thank you,
David
