  1. aVaccination group was vaccinated with NADC30 like PRRSV inactivated vaccine, and sera were collected on indicated days and tested bypeptide ELISA, IDEXX PRRSV X3 Ab ELISA, and VN test
  2. bControl group was not treated, and sera were collected on indicated days and tested by peptide ELISA, IDEXX PRRSV X3 Ab ELISA, and VN test
