Tip of the Needle - over vaccination of animals

Here is another article on the subject of vaccines and how often our dogs etc should have them. My horse hasn't had a vaccination for several years - he is retired - my dogs don't go anywhere to meet other dogs as we have our own meadows to talk in. At least for them, rabies vaccination is now only every 3 years. But they are still pumped up with the rest of the drugs! As one is 15, one 13 and one 9, surely they are well protected without still needing an annual vaccine?

Anyone else feel the same?
