- Legend: DPV = days post vaccination; nf = number of farms; nWV = number of “well vaccinated” farms (farms where the proportion of DT+ was not significantly lower compared to an ideal 95%-immunization coverage); %WV = percentage of “well vaccinated” farms; nfc = number of sampled female calves; n DT + = number of female calves positive to the diagnostic tests; % DT = percentage of female calves positive to the diagnostic tests; asignificant differences with the ideal 95%-coverage
