The result shows that vaccine with propolis is better than that without propolis and can obviously improve antibody titer and enhance immune effect.
The antibody titer and cross-reaction of fish serum were confirmed by ELISA test.
The average antibody titers(agglutination titer)of the Whole-cell vaccine immunization, injection immunization and microencapsulated vaccine oral immunization were respectively 1:19,1:190,1:62;
The RSV antibody titers in neonates and infants decreased rapidly within 6 months after birth and then increased gradually with a maximum level at 7 ~ 14 years old.
Test results, using two different assays, showed high antibody titer for H5N1 on consecutive serum samples taken on days 11 and 15 of his illness.
