We assessed anti-Vi IgG/IgA responses to typhoid conjugate vaccine (TCV) in children enrolled in a double-blind randomized controlled, phase 2 trial in Burkina Faso. Anti-Vi IgG seroconversion and anti-Vi IgA titers were higher in TCV than control recipients at 30-35 months post-vaccination. TCV induces durable immunity in Burkinabe children vaccinated at 15 months.

布基纳法索接种伤寒结合疫苗的 15 个月大儿童出现持久抗 Vi IgG 和 IgA 抗体反应。

我们评估了布基纳法索参与双盲随机对照 2 期试验的儿童对伤寒结合疫苗 (TCV) 的抗 Vi IgG/IgA 反应。接种后 30-35 个月时,TCV 中的抗 Vi IgG 血清转化和抗 Vi IgA 滴度高于对照接受者。TCV 可在 15 个月大时接种疫苗的布基纳法索儿童中产生持久免疫力。
