Just incase you don't have time to read the whole article:

"A small dog half-dose vaccine study, which supports Robb’s theory, was published in the Integrative Veterinary Journal in the Spring 2016 issue.  In this study, Dr. Jean Dodds showed that small breed dogs receiving a half dose of distemper parvo vaccine effectively responded, producing sustained increased antibody levels as measured in a titer test. A study concluding that smaller dogs have a higher risk of vaccine reactions, as well as noting other risk factors, was published in the Journal of the American Veterinary Medical Association in 2005."

"Research published as long ago as 1998 estimates protection from distemper and parvovirus vaccines as lasting 9-15 years. Yes, years."
