A Game-changing Vaccine

Innovation is critical in vaccine development. For decades it was believed that vaccinating young animals was not effective because of maternal antibody interference. The industry needed to find a way to protect young calves from BRD.

Learn from members of the team who brought to market BOVILIS NASALGEN 3-PMH – the first and only intranasal BRD vaccine offering protection against viral and bacterial pathogens.

How to use NASALGEN?

Nasalgen products are designed to make preparation and administration easy without sacrificing powerful protection. Simple steps and instructions are one more way Merck Animal Health Works for you. See details below.

Rehydrate

Mix

Intranasal Administration

Rehydrating instructions

Rehydrate freeze dried vial with part of the accompanying vial of diluent using the transfer needle provided.

Insert the transfer needle fully into the small vial of dehydrated vaccine to release the vacuum.
Insert the other end of the transfer needle fully into the large vial of sterile diluent.
Squeeze enough diluent from the large bottle into the smaller vial to rehydrate the vaccine

Mixing instructions

Mix reconstituted vial well and transfer rehydrated vaccine into diluent vial using transfer needle. Remove transfer needle from the former diluent vial and mix reconstituted vial well. Peel label from the vaccine vial and place on diluent vial containing all vaccine.

With the two bottles still attached, swirl the small vial gently until the vaccine is mixed.
With the small vial upside down, squeeze the large bottle several times to draw the mixed vaccine into the large bottle.
Separate the bottles and remove the vaccine label from the small vial and apply it to the large bottle for proper identification.

Administering instructions

NASALGEN IP and NASALGEN-3 are 2 mL doses administered intranasally into one nostril. One mL of Nasalgen® IP may be administered into each nostril.

For an intranasal vaccine to be effective, the intranasal mucosal surfaces must come in contact with the fluid. Typically, younger calves are less resistant to having their head tilted into the proper position, making it easier to ensure the vaccine can run into the nostril
