Canine
Parvovirus Types 2c and 2b Circulating in North American
Dogs in 2006 and 2007
includes vaccinated dogs - check out the chart on page
2 of the PDF version of the study (Table 1 of the HTML
format)

The CDC's document regarding Parvovirus in general.
Includes info on all strains - 2, 2a, 2b and 2c. References
2c back to the year 2000.

Only an abstract (which I find annoying), but I found
the last line rather interesting:
"No significant associations were found between
CPV type, clinical outcome, breed, vaccination status,
or age."
Also of interest, this report notes that 2c was first
seen in Germany in 1996, 4 years before it was "officially"
reported in Italy.

Another abstract re: parvovirus in Australia. Date 2005.
Needless to say, I can't get my hands on the FULL study
report, only the abstract.
"The vaccine failures investigated in the study
were likely caused not by genetic variation of field
viruses but bymaternal antibody interference in the
response of pups to vaccination."

Italian study published in 2002. Note: Glu-426 is the
"lab" name for parvo 2c. I think it has since
then been formally renamed to 2c to avoid confusion.
