HS Vaccine (Haemorrhagic Septicaemia) — overview
HS vaccine protects cattle and buffalo against a major bacterial cause of sudden death during humid seasons.
Vaccination underpins profitable cow, buffalo enterprises across Punjab, Haryana, and neighbouring states. Missed boosters expose herds to production shocks and trade restrictions.
Schedule and timing
Schedule: Annually before monsoon in most North Indian states. Align farm calendars with block camp notifications and private vet visits. Late vaccination still beats no vaccination during regional risk periods.
Record dates in a herd register to avoid accidental gaps when animals are sold or purchased.
Age and dosage
Age guidance: Calves from 6 months; booster as per vet. Dosage: Standard dose per manufacturer label — usually 5 ml subcutaneous. Always follow manufacturer labels and vet instructions for route and storage cold chain.
Damaged vials or warm storage reduce efficacy — handle vaccines carefully.
Benefits for farmers
Documented benefits include: Prevents sudden mortality during stress periods; Recommended for dairy and fattening herds.
Herd immunity reduces catastrophic loss and stabilises milk income across seasons.
Storage and handling
Maintain cold chain until administration. Use sterile needles, avoid sun exposure on prepared doses, and dispose sharps safely. Train family labour to recognise post-vaccination fever monitoring steps.
Integration with biosecurity
Vaccination works best with quarantine, visitor control, and clean water. Do not assume vaccines alone eliminate all risk — especially where multiple strains circulate.
Purchasing animals — what to verify
Ask sellers for recent vaccination proof before high-value purchases. If records are missing, plan booster visits with your vet after quarantine.

Government camps and private vets
Many vaccines arrive through government camps at subsidised rates; private vets supplement timing flexibility. Combine both channels for coverage.
Next steps
Mark your calendar, update herd records, and locate a veterinarian on PashuMate if you lack a regular provider. Preventive care is the highest-return input for most dairies.
