DiarrVac RCE Emulsion for Injection for Cattle — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

colostrum from vaccinated cows during the first week of life, these antibodies have
been demonstrated to reduce the severity of diarrhoea caused by bovine rotavirus,
bovine coronavirus and enteropathogenic E. coli F5 (K99) and to reduce the
shedding of virus by calves infected with bovine rotavirus or bovine coronavirus.
Onset of immunity: Passive immunity commences with colostrum feeding and is
dependent on calves receiving sufficient colostrum after birth.
Duration of immunity: has not been established.

Common aseptic procedures should be used during vaccination.
Only sterile syringes and needles should be used.
Allow the vaccine to reach room temperature before use. Shake well before and
occasionally during use to ensure that the sediment is dissolved prior to
administration.
For the 90 ml and 450 ml pack sizes, it is recommended to use automated dosing
equipment to protect the stopper against damage from multiple piercing.
One dose: 3 ml
One dose in the course of each pregnancy, given in the 12 – 3 week period before
calving is expected.
Feeding of colostrum
The protection of calves depends on adequate ingestion of colostrum from
vaccinated cows. Measures should be taken to ensure that calves receive sufficient
amounts of colostrum within the first few days of life. If calves do not get enough
antibodies through the colostrum soon after they are born, they will have failure of
passive transfer of antibodies. It is important that all calves receive as much
colostrum as possible from the first milking within the first six hours after calving.
It is recommended that at least 3 litres of colostrum are fed within the first 24 hours
and this amount is equivalent to approximately 10% of the weight of a calf.
To achieve optimum results and to reduce infection pressure on the farm, a whole
herd cow vaccination policy should be adopted.

None.

Cattle (pregnant cows and heifers):
Common
(1 to 10 animals / 100 animals

, elevated temperature
1
5–7 cm in diameter which typically resolves within 15 days.
