A bat population could have a vaccine that works. Bats are injected with a lab-modified viral vaccine and spread it to other bats. A credit was given to the person by the person, who was:
Since the first lab-modified virus capable of replicating was created in 1974, an evidence-based consensus has emerged that many changes introduced into viral genomes are likely to prove unstable if released into the environment. Many virologists would question the release of genetically modified viruses that retain the ability to spread. Self-spreading vaccines for animals are being researched in Europe and the US despite concerns, according to researchers from Germany, South Africa, the United Kingdom and the United States. They are meant to limit the spread of diseases between animals and humans.
Vaccines for wild animals and humans against diseases such as tetanus and polio are already in use. In all modified virus applications, rigorous efforts have been made to eliminate the capacity of the viruses to spread in the environment between host individuals.
The tools needed to generate a vaccine that can be self-spreading have been around for a while. A field trial in 2000 demonstrated the transmission of a self-spreading rabbit vaccine. The European Medicines Agency did not approve the vaccine for marketing. Filippa Lentzos of King's College London says that self-spreading vaccines can be developed using methods that already exist.
There is a vaccine against swine fever.
In Spain, scientists are currently vaccinating pigs with self-spreading viruses that have not been modified in a laboratory against African swine fever as part of contained experiments. A four-year research project that sought to identify strategies for self-spreading vaccines has ended in the U.S. The Defense Department's research agency is funding experimentation to determine if lab-modified self-spreading animal vaccines can prevent the spillover of pathogens to U.S. military personnel in areas where they operate.
"If, as is argued, self-spreading vaccines are potentially transformational in a wide array of agricultural, medical and conserve uses, then developers and funders should commit to address needs within their own borders, rather than continue to propose equatorial nations for field testing." This will increase the chances of a robust debate among fellow citizens and nations about the wisdom of self-spreading viral approaches in the environment. The EU funded project to address a serious pig disease within its own territories could be seen as a step in this direction.

The US and Europe are developing vaccines for animals based on viruses that spread on their own.
