TI  - Randomised, placebo-controlled trial of a live vaccine against porcine 
      reproductive and respiratory syndrome virus in sows on infected farms.
PG  - 475-8
AB  - A randomised, double-blinded, placebo-controlled study into the effectiveness and 
      safety of a vaccine against porcine reproductive and respiratory syndrome virus 
      (PRRSV) was carried out on three farms with a history compatible with chronic 
      PRRSV infection; representative groups of sows and gilts were injected with a 
      live vaccine against PRRSV, and during the next six weeks no side effects were 
      observed. The remaining sows and gilts on the three farms were then vaccinated 
      with the same vaccine. Again, no side effects were observed. There were 
      significant reductions in abortion, reproductive disease, returns to oestrus and 
      the numbers of stillborn pigs per sow, and significant increases in the numbers 
      of liveborn pigs per sow and weaned pigs per sow among the vaccinated animals.
