Make sure autumn-born calves are up to date with any vaccines used to improve herd health, especially when following a programme that requires a booster shot in a two-part vaccine.

Calves born from August to November will be old enough to get the first shot of a pneumonia vaccine, as well an IBR vaccine. These may be given into the muscle or up the nose.

Follow-up shots

Depending on the product being used, a second shot may be required a few weeks after the primary shot, while other products require a booster shot to be administered after a few months.

Vaccines do not eliminate the risk of disease, nor do they make up for poor management. But when administered correctly and there is good herd health practices in place, then the disease risk is greatly reduced.

Where calves are on a clostridial vaccine programme, make sure the booster shot is given around four weeks after the primary shot to give effective long-term cover.

Neglecting to give the booster shot greatly reduces the efficacy and cover period of the vaccine used.
