Hipradermic®, a needle-free jet injector for intradermal application of swine vaccines, has been on the market since 2015. During this period, this vaccination device has been used by customers from more than 30 countries to carry out vaccinations in both sows and piglets. Thanks to the feedback provided by users several improved versions have being released, being the last one, Hipradermic 3.0 recently released.
Users' thoughts and experiences are the most relevant tools to discover the main characteristics and advantages that this intradermal needle-free device can offer to swine producers.
User-friendly and better time management
A vaccination program is an essential part of any producer's toolbox to maintain herd health and it has to be safe and easy to carry out for employees. Pig producers should get the most value from the vaccines they use, and from their employees' time spent administering them.
For Alexander Igolnik, veterinarian at JSC Chistogorosky, Russia, with 12,000 sows in production “Hipradermic® allows us to easily and quickly carry out mass vaccination of animals. The device proved to be very reliable and very easy to use, the staff quickly mastered the work with Hipradermic®”.
Markus Bender is the owner of a 200-sow farm in Germany. For two years, Markus has been vaccinating piglets by intradermal application “with Hipradermic® 400 piglets can be vaccinated in around 30 minutes and only one person is needed”.
Erika Romerde, Farm Veterinarian, JLD Livestock Corporation, Sta. Maria, Philippines. “It is actually easy to use, efficient (especially with mass vaccination) and safe to use”.
David Owers runs a 700-sow farrow to finish unit in Lincolnshire, UK. “Sows are vaccinated from behind while they eat, meaning there is less chance of staff being trapped or crushed”.
Reduction of the risk of spreading viremic disease
The risk of spreading diseases can occur by injection (iatrogenically), when re-using the same needle-syringe on multiple animals.
Sara Silva is the person in charge of the Agro Pecuaria Passadouro farm, Leiria, a high-density area located in the central region of Portugal. When a PRRS outbreak occurred in early 2018, the vet decided that a piglet vaccination program was needed.
“We chose the intradermal route over intramuscular mainly to avoid disease spread between individuals. When we use intramuscular administration, we try to change needles between litters, but it’s often impractical to do this. With Hipradermic® we can go faster without having to worry about disease spread!“.
Markus Bender agrees on that approach “Needles go through the skin and virus can become attached, making it possible to spread the disease from one animal to the others. Intradermal application works without a needle as it is a high-pressure stream that penetrates into the skin”.
Elimination of the possibility of broken needles and damage to the carcass
The elimination of broken needles and associated carcass trim are important in pork quality assurance. These factors have been targeted by different national pork producers’ associations in the “One Is Too Many” needle awareness campaign.
In this respect, Alexander Igolnik states that “Hipradermic® avoids the problems that accompany the use of needles. For example: needles can bend or even break, which significantly slows down the vaccination process. Also, with needles sometimes you cannot get into the muscle, leaving the vaccine in the fat layer.
Plus, with intramuscular administration of the vaccine, local inflammatory reactions, such as abscesses, are possible. We have vaccinated more than 60,000 sows with Hipradermic®, and not a single abscess”.
Edwin van 't Foort is the person in charge of the farrowing unit on Maatschap van de Lagemaat farm, Netherlands. “Since we started vaccination without needles, we see fewer abscesses”.
Less stress and pain for the animals
Intradermal injection is considered to be a less invasive technique, causing less stress and pain for the animals. Lowering the pain and stress of pigs in production has been shown to increase their general health and growth capabilities¹.
Sara Silva noticed that ”when using the device to vaccinate sows, we have much less stress in the animals and mass vaccinations are a lot faster, not to mention operator fatigue, which is higher if we use IM products”.
Edwin van’t Foort has noticed that after vaccination with Hipradermic® “the sows remain lying down or standing where they are. They don’t suffer from it”.
Piyawan Nonsaket works in a swine farm located at Lopburi province in Thailand and “observed no evidence of adverse reactions and a decrease in fear and pain in vaccinated pigs.”
Markus Bender “piglets are more relaxed during the vaccination process with a needle-free device and the application is less painful and piglets do not scream during the vaccination.”
Proper vaccine administration is a critical component of a successful immunization program. It is a key part of ensuring that vaccination is as safe and effective as possible².
Alexander Igolnik “there are no errors in the introduction of the vaccine. The vaccine always gets into the animal body in the right dose”.
Samran Pongsa owns a 1000-sows farm in Thailand. “Hipradermic® as a needle-free device displays accuracy in the administration of the vaccine with an optimal dose delivery on the surface of the pig’s skin”.
All vaccination data generated by Hipradermic® are recorded on HIPRAlink® Vaccination, allowing the management, control and analysis of the vaccination activity. Being the first and only needle-free device that automatically recognizes the vaccine and traces the vaccination process.
Ronn Catinding, owner, Pilpride Feed and Livestock Corporation, Pulilan, Bulacan, in Philippines. “We could even check offsite what happened in a certain mass vaccination and the vaccination history of our farms”.
Sonia Bel, veterinarian in Coop. Ganadera de Caspe, Spain: “I can know how the vaccination session went even when I am not at the farm“.
Intradermal vaccination with a needle-free device as Hipradermic®, is an advanced, easy and reliable vaccination method that improves the lives of both users and animals. Every time, more producers and veterinarians from different countries around the world are using this vaccination system conscious of the benefits they can get, that for sure will help them to tackle in a better position some of the challenges the swine industry is facing.
