No significant difference was found between the groups both one and 12 months after primary immunization, and all the serum tetanus antitoxin concentrations were above the protective level. Immunization with DPT vaccine both with monthly intervals completed at 4 months of age and with two-month intervals completed at 6 months of age provided adequate protection against tetanus, and protective antitoxin levels persisted until the first booster a year after the third dose of DPT vaccine.eninfo:eu-repo/semantics/closedAccessaccelerated immunization scheduleprimary immunizationserum tetanus antitoxinArticle253189191Q3
