Ag Notes: Handle vaccine properly

October 27, 2004|JERRY LITTLE

Part of good herd management is to properly handle and store vaccines so they will provide effective disease protection for animals.

This will help develop a strong immunity to the diseases which you are vaccinating for.

Be sure to buy vaccine from a dealer who uses good storage and handling. After purchase, store vaccine in a cool, dark place such as a refrigerator as soon as possible. Do not leave vaccines on the dashboard of your vehicle because temperatures, light or freezing will cause inactivation.

Properly store vaccines until you are ready to use them; then, expose only the you will use in about one hour. If you will be working several animals, keep in a cool, insulated container and remove them as needed.

Modified live vaccines are especially sensitive to being mishandled.

Most of these vaccines must be rehydrated by adding a sterile solution to the freeze-dried material. Use a transfer needle to remove the fluid and transfer it into the vial containing the vaccine. If you are using a syringe and needle to transfer the diluent, use a clean needle to withdraw vaccine to keep from contaminating the entire vial. In addition to preventing contamination, it may help keep "knots," or abscesses, from forming at the injection site.


Rehydrated modified live vaccines are effective for just a few hours under perfect Exposure to sunlight and heat will quickly inactivate them, usually within 45 minutes.

When using a modified live vaccine refrain from disinfecting the needle between animals, because the vaccine can be killed if only a drop of disinfectant remains in the needle. Instead dispose of needles and change syringes between every 10 to 15 animals.

Always read and follow vaccine label directions.

For more information contact your local county extension service office or your veterinarian.

Keep it

A man is going out of town and needs to board his horse for a couple of months.

He asks a local farmer about it and the guy says, "Sure, but I charge $50 per week, I keep the manure."

Well, the fellow can't afford this, so the farmer refers him to ol' Jones, down the road.

When approached with the request, Jones said, "Yup, I can do it for $40 a week, and I keep the manure." This is still too much, and Jones suggests that he try Mr. Brown.

When our desperate friend asks Mr. Brown, he is surprised to hear "Sure, Sonny. I'll be glad to for $5 a month." With delight, the young man exclaimed, "WOW! I suppose for that price you'll want to keep the manure."

The old man looked at him with kind of a squint, and says, "Feller, for $ 5 a month, there ain't gonna be none!"
