Mystery surrounds the extent to which horsepox virus may have contributed to the vaccinia virus used to eradicate smallpox. With few documented cases of horsepox in recent years it may never be solved, says José Esparza, who seeks to raise awareness of the potential historical and scientific importance of identifying new cases.

TLDR
A historical investigation revisits the mysteries of the smallpox vaccine and reveals an intricate evolutionary relationship of extant vaccine strains, suggesting the lymph was probably a vaccinia strain or a horsepox-like virus.

TLDR
No major change concerning the likelihood of a “resurrection” of smallpox emerges from this publication, but it is evident that the scientific community, politicians, decision makers, and the lay public have to continue, and probably intensify, a discussion on benefits and risks of synthetic biology in a broader sense.
Molecular and genomic characterization of a novel equine molluscum contagiosum-like virus
TLDR
The first full-length genome sequence of an equine molluscum contagiosum-like virus (EMCLV) directly determined from skin biopsies of a horse with generalized papular dermatitis suggests that EMCLV should be nominated as a new species within the genus Molluscipoxvirus.
The Evolution of Poxvirus Vaccines
TLDR
This review highlights the evolution of poxvirus vaccines, from first generation to the current status, pointing out how different vaccines have emerged and approaches that are being followed up in the development of more rational vaccines against a wide range of diseases.
Beyond the myths: Novel findings for old paradigms in the history of the smallpox vaccine
TLDR
This poster presents a poster presented at the 2016 World Conference of the American Association for the Advancement of Pasteurization of Viruses ( AACS) to discuss the science and technology behind the discovery of Clostridium difficile and its role in infectious disease.
Equination (inoculation of horsepox): An early alternative to vaccination (inoculation of cowpox) and the potential role of horsepox virus in the origin of the smallpox vaccine.
TLDR
It is reported that a commercially produced smallpox vaccine, manufactured in the United States in 1902, is genetically highly similar to horsepox virus, providing a missing link in this 200-year-old mystery.
Construction of an infectious horsepox virus vaccine from chemically synthesized DNA fragments
TLDR
This work believes this is the first complete synthesis of a poxvirus using synthetic biology approaches and supports further development of scHPXV as a novel replication-proficient smallpox vaccine.

Chasing Jenner's Vaccine: Revisiting Cowpox Virus Classification
TLDR
Genotypic data presented herein indicate that CPXV is not a single species, but a composite of several species that can infect cows, humans, and other animals and suggest that both wild and modern vaccine strains of Vaccinia virus are most closely related toCPXV of continental Europe rather than the United Kingdom, the homeland of the vaccine.
Genome of Horsepox Virus
TLDR
The genomic sequence of horsepox virus (HSPV) isolate MNR-76, an orthopoxvirus (OPV) isolated in 1976 from diseased Mongolian horses, indicated that HSPV contains unique genomic features likely contributing to a unique virulence/host range phenotype.

TLDR
Two strains of pox virus isolated from naturally infected horses were adapted to the chorioallantoic membrane (CAM) of developing chick embryos and to tissue cultures and the CAM, suggesting an immunological relationship between the horse virus and vaccinia and cowpox viruses.
