Infected cats develop antibodies and kittens appear to be protected initially for the first one or two months of life by maternally derived antibodies (Wills, 1986). Active immunity

Immunity

Chlamydia felis vaccines are non-core. Both inactivated and modified live (attenuated) vaccines, based on whole Chlamydia organisms, are available, but only as components of multivalent vaccine preparations. Vaccines are effective in protecting against clinical manifestation of the disease, however, not against occurrence of infection (Wills et al., 1987). No reliable data are available to compare the efficacy of inactivated versus modified live vaccines.

The nature of the protective immune responses to Chlamydia infection is uncertain. However cellular immune responses are believed to play a crucial role in protection (Longbottom and Livingstone, 2006). The MOMPs and POMPs are important targets for protective immune responses in other species (Longbottom and Livingstone, 2006) and have been shown to exist in the cat (Harley et al., 2007).
