Humans have been unjustly prevented from associating with an allergy this week, following news of a resurgence in a potential vaccine that makes cats less likely to cause allergies. But as this research promises, a finished product will not be available anytime soon.
The vaccine in question was developed by the Swiss-based Hypocat and is the company's flagship experiment and name drug. This April, Hypocat published the results from a vaccine study. And this is the news that the internet has, with reasons gone into void, started buzzing again. ] The vaccine does not attempt to disrupt the immune system of people who are allergic to cats, as do other immunotherapies such as allergic shots. Instead, it tries to train the immune system of cats to go after a specific protein, or allergy, that they can naturally produce called Fel d 1. This trick should be accomplished by hitting a Genetically modified version of a protein like a particle virus derived from a plant virus (being just a particle, it should not be capable of causing disease).
About 90 percent of people with cat allergy produce antibodies to Fel d 1. Thus, if successful, the vaccine usually cat hypoallergenic cats by greatly reducing the amount of Fel d 1 they do and eventually flow into our noses and mouths. Cat owners will happily tell you that their felines are capable of responding to themselves …

In the study, that's what the felines seem to be doing vaccine. Throughout the various experiments, more than 50 young cats were dosed with the vaccine, which was managed through a shot on their hind legs. In the latest experiment, cats were given three doses for nine weeks; some cats also get a booster shot six months later.
All cats, they reported, developed a prolonged immune response to the allergy, and booster shot helped maintain antibody levels. Antibiotics taken from the cats' blood also seemed to neutralize Fel d 1 in the lab, while the cats themselves produced less Fel d 1 in their saliva and tears. And when these cat samples are mixed with blood extracted from real human patients with cat allergy, they cause less of an allergic reaction.
Most important for animal lovers, the vaccine does not appear to cause serious or long-term side effects in cats. One possible reason for this is that Fel d 1 has no important function in cats, as we know it. Some cats are naturally very low on Fel d 1, without obvious health problems. The vaccine also does not remove the protein.
This is exciting news, but it's also early, "pre-clinical" data. The company said it was in discussions with both drug approval agencies in the United States and that it began to provide the basis for mass production and clinical trials involving people. But even though these trials have begun today and the vaccine has been passed on to them with flying colors, you will still have to wait years before they hit the market. A similar vaccine for the company's development dogs, called Hypodog, is further back in the pipeline. . Just know that you need to be patient for a long time.
