Vaccines prepared with protamine sulphate or with calcium phosphate were no more immunogenic than the untreated parent suspensions.<\/jats:p><jats:p>Cross tests with aqueous vaccines revealed antigenic differences in the TRIC agents examined, in terms of their ability to protect against conjunctival challenge.

This reaction may be an expression of a hypersensitive state induced by relatively ineffective vaccines; like immunity, it is unrelated to the titre of CF antibody in the serum.<\/jats:p>","DOI":"10.1017\/s0022172400040833","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T10:25:16Z","timestamp":1242383116000},"page":"529-544","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":7,"title":["Immunogenicity of experimental trachoma vaccines in baboons: II.
