Survival and genital lesions in immunized guinea pigs after intravaginal challenge.

<p><b>(A)</b> Survival curves. The table shows urinary retention and hind limb weakness during the first two weeks. <b>(B)</b> Days with acute genital lesions. <b>(C)</b> Days with recurrent genital lesions. Tables below (B) and (C) show the numbers used to generate the graphs. <b>(D)</b> Vaccine efficacy of gD2, trivalent, or trivalent + gD2 compared with mock. P values for (A) were calculated using Prism software by linear regression, while P values for (B-D) were calculated using Fisher’s exact test, except that severity of disease was calculated by Student’s t-test.
