R. ChinaVaccination is the most effective and cost-saving way to hepatitis B virus (HBV) infection. Collective data suggest that helminthinfections affect immune responses to some vaccines. Therefore it is important to reveal the effects of helminth infectionson protective vaccines efficacy in countries with highly prevalent helminth infections. In the present work, effects of Trichinellaspiralis infection on the protective efficacy of HBV vaccine in a mouse model were investigated. This study demonstrated thatthe enteric stage of T. spiralis infection could inhibit the proliferative response of spleen lymphocytes to hepatitis surface antigen(HBsAg) and lead to lower levels of anti-HBsAg antibodies, IFN-γ and IL-2, along with higher levels of IL-4 and IL-5. However,these immunological differences are absent in the muscle stage of T. spiralis infection. The results suggest that the muscle stage ofT. spiralis infection does not affect the immune response to HBV vaccination, while the enteric stage infection results in a reducedimmune response to HBsAg.Keywords: Trichinella spiralis; protective efficacy; hepatitis B; vaccineleijiahui@ hust.edu.cnJ <strong>Vaccines</strong> Vaccin <strong>2013</strong>ISSN: 2157-7560, JVV an open access journal<strong>Vaccines</strong>-<strong>2013</strong>July 29-31, <strong>2013</strong>Volume 4 Issue 5Page 110
