  1. Calves were infected intranasally with live BRSV 28 days after vaccination with one dose of the inactivated BRSV-PI3-Mh combination vaccine.
  2. *According to the information of the manufacturer of the assay, values above the cut-off level (0.207) have to be interpreted as positive - indicated by the bold letter type
  3. # Average values with different superscript letters are significantly different (p < 0.05) from each other.
