If I only receive one dose what is the percentage of success?

Hello,

According to my research, there are no studies on the effectiveness of a single dose of Shingrix. When both doses are obtained, this vaccine is 97% effective in preventing shingles. You can visit this link for general information related to the shingles vaccine.

Hopefully this answers your question,
