Vaccines are one of the greatest achievements in medical science. In recognition of their role in the control of equine disease, the Equine Veterinary Journal (EVJ) has produced a special collection of articles on equine vaccine research, available free online here.

Vaccines as infectious disease control in horses

Vaccines as infectious disease control in horses

The Equine Veterinary Journal has produced a special collection of articles on equine vaccine research, available free online to horse owners and care takers everywhere. New window.

Vaccination involves the administration of a biological preparation that stimulates the immune system to fight a specific disease and recognize and destroy it in any further encounters. It is the most effective method for the control of infectious diseases in humans and animals.

Guest edited by Janet Daly, Associate Professor in Emergent Viruses, School of Veterinary Medicine and Science at the University of Nottingham and Pablo Murcia, EVJ’s Latin American Editor, based at the Institute of Infection, Immunity and Inflammation, College of Medical, Veterinary and Life Sciences, University of Glasgow, the collection covers aspects of the control of equine influenza, immunology in young horses and herd immunity.

The first inactivated virus vaccines for the control of equine influenza became available in the late 1960s, and there are now several licensed vaccines for horses. The protection induced by an equine influenza vaccine depends on the antigenic relatedness of the strain(s) included in the vaccine to circulating strains encountered by horses.

However, a vaccine containing a mismatched strain can still limit clinical signs of disease. In the paper What can mathematical models bring to the control of equine influenza? Janet Daly and collaborators confirm that because a mismatched vaccine is poor at suppressing virus replication and shedding, the likelihood of a large outbreak occurring increases.

In order to ascertain whether the equine influenza vaccines in use in Japan remain appropriate, Yamanaka et al’s 2015 paper assesses The potential impact of a single amino-acid substitution on the efficacy of equine influenza vaccines and suggests that vaccine efficacy may be compromised as a result of a single amino acid change.

The importance of including a relevant strain in vaccines emphasizes the need for effective surveillance strategies. In the article on the Surveillance of equine influenza viruses through the Réseau d'Epidémio-Surveillance en Pathologie Equine (RESPE) network in France from November 2005 to October 2010 Legrand and collaborators show how surveillance improved the detection of equine influenza in France and highlight the importance of training in veterinary surveillance.

In addition to vaccine composition, strategic timing of delivery of vaccines to pregnant mares, foals and youngstock is an important factor for vaccine efficacy according to Perkins and Wagner’s paper The development of equine immunity: current knowledge on immunity in the young horse.

Following this, a paper by Davis et al on the characterisation of immune response in healthy foals when a multivalent vaccine was initiated at age 90 or 180 days concludes that the immunity gap could be reduced if required.
