Elise Myers (MSD) spoke on the evolution of vaccines and tolerance of anticoccidials, among other topics, during the 1st PoultryUniverse Coccidiosis Congress in Curitiba, Brazil.
Thank you for your question.
My comment was meant to highlight the fact that these are all live coccidiosis vaccines that work through a similar process of initial infection, followed by subsequent reinfection until immunity is developed in the host. Many companies have made changes to how their live coccidiosis vaccine is applied (through new equipment or application methods) or formulated (through strain attenuation, the inclusion of new strains, or the alteration of oocyst counts etc.) however, the product itself remains at its core a live coccidiosis vaccine. The purpose of the talk was to stimulate discussion in the panel and audience about new ideas in the space that were not based on traditional coccidiosis vaccine technologies as we know them today. As this lecture did not have at its core the goal of discussing the pros and cons of attenuated vs non-attenuated products, I did not describe this at length, but would be happy to have a discussion offline to answer any questions that you may have.
Thanks again for reaching out-
Thanks for your idea for the hybrid program. Is it possible to make a hybrid program by using herb instead of coccidiostat with the vaccine for Antibiotics free chicken?
Thank you for the clarification, probably there was a misunderstanding since from what I know, there were some efforts from a company to develop a killed vaccine, which was by the way included in the list you mentioned.
The results also you shared regarding anticoccidials effectiveness are very meaningful.
Good day,
I have a question about your slide mentioning vaccines and technologies.
Don't you think that there was some efforts, regardless commercialization, to improve coccidiosis prevention in broilers, either by using specific devices to improve the vaccination process or to add underestimated strains, such as mitis or praecox?
Also, can you give us more details when you mentioned that there is no big difference between attenuated and non-attenuated, what is then the benefit from each technology, and most important why then a so important gap price (which can be up to x5 times for attenuated bigger than non-attenuated)
Greetings
