Vaccinations
Remember!
• Vaccination does not give absolute
100% protection to each and every
animal or every herd
• Vaccination does not replace good
biosecurity/biocontainment
management practices
.
Vaccine Handling
• Rules #1-3
1. Read label
2. Read label
3. Read label
Label Directions
• Proper temperature
– Refrigerate most vaccines
– Refrigeration means 400 F, not 200, not 600
• Proper route of administration
– IM (intramuscular)
– SQ (Subcutaneous)
– IN (Intranasal)
– Oral
.
Label Directions
• Proper species
• Proper dose
• Proper time (including boosters as
necessary)
.
Vaccine Types
• Killed
• Modified Live (MLV)
• Antibodies/Antitoxins .
Vaccine Types
• Killed
– all organisms are inactivated
– No potential for any live germs
to cause disease
.
Vaccine Types
• Killed
– Induce primarily antibody
development in the vaccinated
animal against very specific
organisms
– Usually multi-dose vials
– Usually requires booster dose
first time
.
Vaccine Types
• Modified Live Vaccine (MLV)
– Live disease-causing organism is
treated in a way such that it
induces an immune response
without causing disease
– Modern technology has made this
very safe
.
Vaccine Types
• Modified Live Vaccine (MLV)
– Induces two forms of protection
in the animal: antibodies as well
as cell-mediated immunity
– Typically involves mixing liquid
and dry components and must be
used immediately
– Usually does not require a
booster first time
.
Vaccine Types
• Antibodies/Antitoxins
– Created by hyperimmunizing animals and taking
antibodies from their serum and putting into oral or
injectable form
– Allows for instant presence of antibodies to fight
disease
– Few exist - most common, E coli (First Defense),
tetanus antitoxin
.
What is the best, all natural
vaccine we have?
Colostrum
• The future of your herd is
born with NO antibodies
Colostrum & Calves
• Antibodies in colostrum are required
for the first several months of that
calf’s life to fight off ALL infectious
agents, including scours, navel-ill,
pneumonia
• Antibodies are “herd-specific” for
each farm
Colostrum & Calves
• ASAP – not 12 hours later
• “4 quarts in 4 hours”
• Minimum 100 grams
immunoglobulins
(antibodies)
.
Colostrum & Calves
• Colostrum and
feeding containers
must be CLEAN
• Cow should be
Johne’s negative and
BLV (Leukosis)
negative in tested
herds
.
Colostrum & Calves
• We can influence the antibodies
in colostrum with proper
vaccinations at the proper time
Summary
• Biosecurity and biocontainment are not just big words to
be ignored
• We need to reconsider how we bring additions into our
herds – what risks are we comfortable with?
• We need to evaluate how we handle different age
groups of cattle on our farms
• Vaccination is VERY important but NOT a substitute for
good management
• We need to develop a vaccination program for every
animal in every herd
• Colostrum, colostrum, colostrum
