Sandra Barroso, researcher of the Services of Viral Immunology and Preventive Medication of the UCM, explained to Agencia Sinc the promising success of experiments with the new vaccine: “In our research we clearly show a superior efficacy of this vaccine to limit the viral replication of SARS-CoV-2 in cats, which it would enable handle transmission among animals and avoid them from performing as likely sources of an infection. “
Journal Study in veterinary sciences revealed the results of the study, which was conducted at the Veterinary Health and fitness Surveillance Middle (VISAVET) of the Veterinary College of the UCM. The Microbial Immunology Device of the Carlos III Overall health Institute also collaborated in the investigation.
Barroso describes the motives for the research, which is component of the Analyze of the probable effect of COVID-19 on animals and lynxes: “Whilst Covid-19 ailment is not at the moment of great relevance in veterinary drugs, the consistent physical appearance of mutations in the virus could lead to the emergence of new variants that plainly affect animals.”
The experimental system
The to start with phase of the method consisted of intramuscularly vaccinate two cats with the experimental vaccine and then be monitored search for possible secondary reactions. Serum samples ended up then taken to consider antibody creation.
Just after 30 days of vaccination, the cats have been taken to a superior biosecurity laboratory with each other with two command animals, exactly where they had daily veterinary attention and they have had environmental enrichment to maximize their effectively-getting. As soon as there had been contaminated with the SARS-CoV-2 virus.
Soon after a 21-day period of time of an infection and evaluation of ailment response, the scientists concluded that “the experimental vaccine proved productive in this regard, considering that, in the scenario of just one of the vaccinated animals was totally prevented from an infectionwhilst in the other it was confined to the area of the higher respiratory tract and no excretion of infectious virus“.

In addition, each cats confirmed a solid immune reaction centered on neutralizing antibodies which served command the an infection. Having said that, the researcher regrets that “we simply cannot rule out new scenarios in which the epidemiology of the sickness alterations. For that reason, it is important to have management and prevention equipment for the distinctive sensitive species”.
