In the report “Comparison of anamnestic responses to rabies vaccination in dogs and cats with current and out-of-date vaccination status” (J Am Vet Med Assoc 2015;246:205–211), the name of the individual in footnote a who provided information regarding rabies vaccine formulations is incorrect. The correct individual is Richard Chambers of Zoetis.

Also, some clarification is needed regarding the statement in the second paragraph of the section on “Classification of rabies vaccination status” that “A cutoff of 3 years since the last vaccination was used regardless of whether the last vaccine administered had been licensed for a 1-year or 3-year duration, because the antigenic mass, carrier, adjuvant, and other characteristics of 1-year and 3-year vaccines from 2 companies2,a were reportedly identical.” According to Merck Animal Health, although the formulations for their 1-year and 3-year rabies vaccines may be similar, the resultant potencies can differ and one should not assume that the performance of a 1-year vaccine will reliably be equivalent to the performance of a 3-year vaccine. Both vaccines are tested to ensure that they pass USDA-mandated potency requirements.
