“About 10 to 18% of people who get shingles will experience PHN.”
“In adults 50 to 69 years old who got two doses, Shingrix was 97% effective in preventing shingles;;In adults 50 to 69 years old who got two doses, Shingrix was 91% effective in preventing PHN。”
假定一万成年人,三分之一3333人可能患带状疱疹,有神经痛的人群是333-600人。
注射疫苗后,患带状疱疹人数减少为3333X3%=100,患带状疱疹神经痛减少为333X9%=30及600X9%=54。
所以,不打疫苗不患带状疱疹的可能性是67%,打疫苗不患带状疱疹的是99%。不打疫苗不患神经痛的可能性是93%-97%,打疫苗后不患神经痛的是99.4%-99.7%。打疫苗后不患神经痛的可能性最多增加6%!
