Equivac

Equivac is a brand of veterinary vaccines for horses marketed by Zoetis (formerly Pfizer Animal Health). The product line is best known for Equivac HeV, a vaccine developed to protect horses against Hendra virus, a zoonotic pathogen that can be transmitted from horses to humans. The Equivac brand has in the past included vaccines targeting other common equine diseases as part of standard vaccination programs, such as vaccines against equine influenza and tetanus, though exact product availability varies by country and over time.

Origin and corporate history: The Equivac line originated with Pfizer's animal health division. Following the spin-off of Pfizer Animal Health as Zoetis in 2013, the Equivac products were brought under Zoetis's portfolio and continue to be marketed internationally under the Equivac name.

Usage and administration: Equivac vaccines are administered by licensed veterinarians or trained staff, given by intramuscular injection according to product labeling and veterinary guidance. Dosing schedules typically include a primary series followed by ongoing boosters, with variations by disease and region.

Regulatory status and safety: As with other veterinary vaccines, Equivac products are subject to regulatory approval in the countries where they are sold. They are designed to be safe and effective when used as directed; adverse events are monitored through pharmacovigilance programs.
