Gerek normal ve gerekse zorunlu aşılama programının ön gördüğü
şekilde HB1 ile yapılan burun-göz aşılamala.rından sonra istenil-
en bağışıklık temin edilemedi : Kırkbeşinci ve 4,5-5. aylarda yapılan
odele aşılamalarından sonra meydana gelen H.l antikorları bağışıklık
limitleri içerisinde olup bir ay devam etti.
HB1 ile yapılan ilk aşıdan sonraki uygulamaların LoSota suşu
ile içme suyu veya pülverize veyahut yağ adjuvanlı odele aşısı şeklinde
uygulanmasının daha olumlu olacağı kanaatindeyiz.
