Pinkeye protection.

Look to stop pinkeye before it starts. Boost immunity against Moraxella bovoculi with a new pinkeye vaccine now available from Merck Animal Health.

Pinkeye vaccines are a critical part of a three-step approach to managing pinkeye, including fly control and pasture management.

An Effective Approach at Preventing Pinkeye

M. bovis

The major cause of pinkeye is due to a bacteria called M. bovis. Vaccines such as BOVILIS® PILIGUARD® PINKEYE, BOVILIS® PILIGUARD® PINKEYE+7 and BOVILIS® 20/20 VISION® 7 with SPUR® from Merck Animal Health are available to help prevent against this pathogen.

M. bovoculi

In a recent study of 466 pinkeye cases, up to 80% of cases were found to include M. bovoculi alone, or along with M. bovis1.

It Takes Two

Utilizing a combination approach to vaccination against M. bovis and M. bovoculi helps your herd gain the maximum protection they need against pinkeye.
