Although a standardized treatment protocol has not yet been developed — and it will probably vary according to the type of cancer involved — managing patients
who respond to the vaccine promises more hope than does treatment with gene - targeted chemotherapy alone.
That said, you might get a runny nose or slight fever after receiving either form of the vaccination, but «thats just your immune
system responding to the vaccine — its not the actual flu,» assures Melinda Wharton, MD, deputy director of the Centers for Disease Control and Prevention (CDC) s National Center for Immunization and Respiratory Diseases.
These weak or killed stimulants, called antigens, are grown in a lab setting, isolated and then mixed with preservatives, stabilizers and a substance like aluminum that will trigger the immune system to
vigorously respond to the vaccine.
So the vaccine needs to contain some pretty toxic ingredients called adjuvants (stuff like aluminum) that make the body
respond to vaccines quicker, longer and more actively.
Note that some cats are genetically «non-responders» and never will
respond to a vaccine no matter how many you give them.
A clue emerged last year with the revelation that those
who responded to the vaccine and fended off HIV tended to produce antibodies against a specific part of the virus's protein shell called the V1 / V2 loop3.
They found that the children who did
n't respond to the vaccine had an elevated expression of inflammatory cytokines but were also less able to respond to cytokine stimulation.
Poland reckons doctors will be able to use the technology to predict whether a person is likely to
respond to a vaccine, or if they are at risk of side effects.
«We devised a different method from the traditional vaccine strategy, and instead of relying on the immune system to
respond to a vaccine, this new, strategy delivers DNA sequences that directly encode the protective antibodies rather than inciting the production of antibodies through an immune response,» said co-lead author of the study Sarah T.C. Elliott, Ph.D., a postdoctoral fellow in Wistar's Vaccine and Immune Therapy Center in the Weiner lab.
A study of a cross section of different puppies showed that the age at which they were able to
respond to a vaccine and develop protection (become immunized) covered a wide period of time.
At 9 weeks of age, 40 % of the puppies were able to
respond to the vaccine.
Research also shows that the vaccine appears to make no difference in catteries where FIP has been endemic, probably since kittens get infected before they are old enough to
respond to the vaccine.
Healthy animals are able to
respond to vaccines a lot better, so if producers aren't deworming their cattle, they could be wasting their money.»
That said, even the best vaccines take some time to provide protection, and vaccine failure may occur when animals enter the shelter already infected with disease, or if they fail to
respond to the vaccine, or are exposed before they are able to do so.
Many factors determine when the kitten will be able to
respond to vaccines.
Unfortunately, many vets recommending Leptospirosis vaccines rely on information provided by the drug companies that make the vaccines, and, as a result, are not aware that the vaccine does not confer immunity — despite the fact that even the AVMA guidelines warn that 30 % of dogs may not
respond to the vaccine.
If your pet is already suffering from an illness, or is receiving an antibiotic, their immune system may not be able to
respond to the vaccine.
Now the puppy's own immune system can
respond to the vaccines and protect him against the diseases the vaccines are for.
If a dog has a compromised immune system, due to illness, parasite load, malnutrition, immune - suppressive medications, or stress its immune system may not be able to
respond to a vaccine.
Protection from disease depends on the immune system's ability to
respond to a vaccine.
Your dog or cat's ability to
respond to the vaccines your veterinarian administers or diseases I might encounter depend on it having a strong, underlying immune system.
We are trying to catch the puppy as soon as possible after that critical window of susceptibility, when his body can
respond to the vaccines.
At Dogtopia, we ask that dogs wait a minimum of 48 hours after a vaccination before returning to Dogtopia to allow the dog's immune system to
respond to the vaccine and to safe guard against any potential (and rare) vaccine reaction.
We now have inexpensive in - house titer testing (Vaccicheck and TiterCHEK)-- titer tests will determine whether your pet has
responded to his vaccines and formed immunity.
When the body is forced to
respond to a vaccine to which it has already established antibodies, this wreaks havoc on the immune system and can cause a number of chronic diseases.
This is a race between immunity and disease, and we are trying to vaccinate that puppy or kitten as soon as their maternal antibody level has dropped low enough that their immune system will be able to
respond to the vaccine, thereby minimizing the amount of time they are unprotected against natural infection.
