When and how often vaccinate Puppies and Mature Dogs

Below here is a copy from an article out of a wonderful magazine called:
Dogs Naturally.
I recommend this article as a "must read"!
We all want to do the very best for our pets, and I can highly advise you to do your own research, and not just listen to your vet alone concerning your pet's health and care. Acquire your own  knowledge, for you to be in control over the welfare of your pet. It may not only be better for your pet, it may save you a lot of money,( and grief) over the long run.
I will just cut a couple of slices out of the article, so you get an idea about the subject.

3 Puppy Vaccination Mistakes: Too Early, Too Often, Too Much


Too Early

When puppies are very young, they are protected from disease by ingesting their mother’s first milk, called colostrum. This rich milk contains maternal antibodies against infectious disease, which the mother passes down to her puppies. The puppy’s immune system is not fully mature, or active, until it is around six months of age, so the maternal antibodies provide passive immunity to each puppy.
When a puppy with a reasonable amount of maternal antibodies is vaccinated, the maternal antibodies will essentially inactivate the vaccine, just as they would a real virus. The maternal antibodies for distemper are fairly predictable and are usually low enough for vaccination to be effective at eight or nine weeks of age. In the case of parvovirus however, the maternal antibodies last a lot longer in most puppies so vaccinating at eight or nine weeks wouldn’t be all that effective.
In a study performed by Vanguard, it was found that a combination vaccine (which typically contains parvovirus, distemper and one to five other antigens), given to six week old puppies had only a 52% chance of protecting them against parvo. This means that the puppy has all of the risk of the vaccine but only half the potential benefit. At nine weeks of age, 88% of the puppies in the study showed a response to the vaccine. At 12 weeks, 100% of the puppies were protected. Some vaccines will provide protection earlier or later.
Vaccinating puppies under 12 weeks of age, and certainly under nine weeks of age, for parvovirus is a high risk, low reward approach. Not only is the parvovirus component of the combination vaccine not all that likely to be effective, it can actually work to block the effectiveness of the distemper component. It also makes the vaccine more dangerous, because the more antigens contained in the vaccine, the greater the risk of autoimmune disease (including allergies, joint disease and cancer).
Moreover, most vets haven’t seen a case of distemper in years, which begs the question: what is the big push to start vaccinating puppies at six to eight weeks of age when the parvovirus component is unlikely to work and it is very unlikely the puppy will come into contact with distemper?

Too Often

After more than 40 years of testing immunity in thousands of dogs, Dr. Ronald Schultz has come to the following conclusion: “Only one dose of the modified-live canine ‘core’ vaccine, when administered at 16 weeks or older, will provide long lasting (many years to a lifetime) immunity in a very high percentage of animals.” That very high percentage is nearly 100%.
The only reason vets give puppies more than one vaccine is that they are trying to catch the small window in time when the maternal antibodies are low enough that they will not block the vaccine, but the puppy is young enough that he is not exposed to viruses in the environment. The point in time when the maternal antibodies for parvovirus wane enough for vaccination to work can vary between eight weeks and 26 weeks. So vets dutifully and mindlessly vaccinate every two to four weeks – with a combination vaccine, not just with parvo – trying to get one of them to work.
Most vets also vaccinate once more at a year of age – just to be certain.

Too Much

The result of these errors in judgement is that puppies receive more vaccines than they need – lots more. They receive a parvovirus component in their first combination vaccine when that part of the vaccine has little chance of working. Most puppies are protected against distemper with the first vaccine if not given too early, yet most puppies are given a combination vaccine containing distemper at 12 to 16 weeks and older – when they really only need the parvovirus.
Most combination puppy vaccines also contain an adenovirus component. Adenovirus has been shown to suppress the immune system for ten days following vaccination. This means that puppies that receive needless vaccines not only suffer the risk of adverse events from the vaccine, but they are more at risk of picking up any other virus or bacterium that crosses their path because their immune system has been overloaded by the vaccine itself.
This is not a good proposition for a puppy taken to the vet clinic to receive his vaccines, because it exposes him to the riskiest possible environment, outside of perhaps an animal shelter, and his immune system will be suppressed while his body tries to fight four, five or even seven different diseases, all at the same time. It’s no wonder that puppies can succumb to vaccine-induced disease – their immune system is simply overloaded at a time when they are exposed to a pretty dangerous place for puppies to be.
Adenovirus is an upper respiratory disease that is self limiting – that hardly seems like a good trade off for immune protection when puppies need it most. The same applies to parainfluenza – and coronavirus which commonly occurs only in puppies too young to be vaccinated anyway. And that’s just the core vaccines.
