Hi,
I had the Zostavax vaccine around 2010 too. I haven't had shingles but understand it can be very painful and serious, even affecting vision at times.

So I've discussed getting the newer Shingrix vaccine with my doctor. It needs to be given in two doses and can have fairly severe side effects.

I've postponed getting the Shingrix because of the side effects but I have MS and want to avoid anything that might cause a fever. Ordinary routine flu shots every year sometimes are a problem for me, and my doctor pointed out that the Zostavax is already providing me with some protection. She'd like to have me get the newer vaccine though.

I'm sorry I don't know if peripheral neuropathy will be made worse by getting the Shingrix vaccine.
