Вот совсем свежая статья в серьезном электронном журнале SF Gate про штамм CPV-2c:

Статья ссылается на Melissa Kennedy, D.V.M., Ph.D., специалиста по микробиологии в University of Tennessee и Dr. Uwe Truyen, исследователя, называемого "гуру собачьего парвовируса".

Цитата:
Do current vaccines protect against CPV-2c? All indications are that yes, they do. Kennedy told me that parvo in dogs simply hasn't changed enough since its emergence 30 years ago that immunity to one strain doesn't also confer immunity to the others.
...
Although adult dogs don't seem to face any greater risk from the new strain than from the older ones, there may be one group that is at increased risk. Very young puppies rely on their mother's antibodies to protect them from disease before they have the ability to form their own. If the mother has antibodies to the older strains, those antibodies may possibly be less effective against CPV-2c.
...
"My biggest concern is puppies who are totally dependent on the antibodies that they got from their mom to protect them, and in that case they don't have any backup," said Kennedy. "Adult dogs have not only antibodies but cell-mediated immunity, which can help protect them." A number of researchers, including Dr. Truyen, have noted the need for studies examining maternal antibodies and CPV-2c.

Вкратце (очень вкратце): статья утверждает, что существующие вакцины способны защитить взрослых собак от нового штамма так же, как и от старых. У взрослых собак иммунная защита вырабатывается клетками организма, усиливая защиту от прививки. Беспокойство вызывают щенки в возрасте до 16-20 недель, иммунитет которых не сформирован до конца. Поскольку штамм новый, щенки не получают соответствующих антител от матери. Также под угрозой оказываются те редкие собаки, которые неспособны вырабатывать иммунитет в ответ на прививку от парвовируса.
