I know many dog owners who don't agree with the need for yearly vaccinations (I'm not one of them, BTW). However, all who take this step continue to do regular immunity testing with their vets (known as titre testing) and in general are dealing with healthy adult dogs, not puppies. In any case, even those owners who reduce the need for vaccination rarely are able to justify lifelong abstention.
We vaccinate every year because we foster, we do transport runs, we use kennels, and because to me it is a simple, easy prophylactic whose benefits outweigh the risks, along with regular worming, flea and tick control. Also, our dogs are very social - we attend many events such as greyhound playgroups, regular organised walks, shows, etc.
Like OwlLady, I am really trying not to be judgemental. All I'll say is that I am old enough to remember the swathes of ill and dead puppies caused by Parvo back in the 80s. Sadly, it is back on the rise. Issues of herd immunity are just as important for dogs as they are for people.
I'd also say that even if you don't expect to use a kennel for holidays, family emergencies and illnesses are never planned and can make alternative care arrangements for your dogs suddenly very necessary. Having dogs who are vaccinated or have a known immune status makes that much simpler whether they are going for kennel care or are heading for emergency foster.
For a perspective from the BSAVA - click here to read their very useful summary of their policy, reasons, and links.
Finally, from a rescue perspective. Nearly every dog that is surrendered is not vaccinated (the exceptions are elderly people parted from pets because of ill health or care home), despite their owners protestations that they are a much loved family pet who has been taken care of. Vax and worming are basics for responsible pet ownership (like going to training classes, wearing ID, etc). Their absence is a red flag for rescues as a marker for an owner that may lead a chaotic lifestyle, may be unable to afford the financial aspects of pet ownership, or may not be willing to invest in preventive health care. You will almost certainly not fall into any of these categories but be aware that rescues see not only far too many dogs with parvo, worms and other preventable health issues but routinely hear many different stories to justify the absence of care. If you could show that you were regularly doing immunity testing then I think the rescue's stance might be different.
