DNA vaccines induce antigen production in the host. It is a plasmid that contains a viral, bacterial or parasite gene. The animal's immune system recognises the expressed protein as foreign, and this can lead to a cellular or humeral response. DNA vaccines overcomes the safety concerns of live-attenuated vaccines.
An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [1] The vaccine delivers molecules of antigen -encoding mRNA into cells , which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus ) or by a ...
Rhipicephalus microplus is best known for being a cattle parasite. However, it has also been discovered in a number of other animal hosts such as domestic water buffalo, wild and domestic goats, horses, wild pigs, various rat species, and humans. [4] R. microplus serves as a vector for numerous pathogens, most notably Babesia bigemina and B. bovis.
The bird flu outbreak in U.S. dairy cows is prompting development of new, next-generation mRNA vaccines — akin to COVID-19 shots — that are being tested in both animals and people. Next month ...

(Reuters) -Twenty-four companies are working to develop an avian flu vaccine for cattle, as the virus spreads among U.S. dairy herds, Agriculture Secretary Tom Vilsack told Reuters on Wednesday.
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
