UNASSIGNED: To analyze the duties of wet nurses at the Hospital Real in Santiago de Compostela (Spain). The secondary objectives were to compare the mortality rate and distribution by parish of the foundlings under the care of the Royal House between 1803 and 1808; and to determine the origin of the Galician foundlings who participated in the Royal Philanthropic Expedition of the Smallpox Vaccine in 1803.
UNASSIGNED: Historiographic study that analyzed sorted and not sorted in series indirect positional and quantitative historical sources.
UNASSIGNED: The duties of wet nurses during the studied period were to provide basic care and cultural instruction. The mortality rate of foundlings fluctuated during that period and their distribution by parish (functional unit of healthcare services at that time) was similar in those years, with a predominance in the provinces of A Coruña and Pontevedra. A total of 5 Galician foundlings from the House analyzed were part of the smallpox vaccine expedition, their names were Juan Antonio, Jacinto, Gerónimo María, Francisco Florencio and Juan Francisco.
UNASSIGNED: During the observed period the wet nurses of the Hospital Real of Santiago de Compostela were in charge of pediatric care. Wet nurses were vital in the role of keeping the foundlings alive and can be considered as one of the forerunners of the pediatric nurse profession at that time.

A large outbreak of monkeypox occurred in 2022, and most people lack immunity to orthopoxvirus. Smallpox vaccination is essential for preventing further smallpox outbreaks. This study evaluated the effectiveness, protection, safety, and cross-immunogenicity of smallpox vaccine in preventing monkeypox infection. PubMed, Embase, Scopus, and Web of Science were searched from database inception to 10 March 2024. We included studies involving \"monkeypox virus\" and \"vaccinations\", and excluded reviews, animal studies, and articles with missing or duplicate data. A total of 37 studies with 57,693 participants were included in the final analysis. The effectiveness data showed that monkeypox infection rates were lower in the smallpox-vaccinated group than in the unvaccinated group (risk ratio [RR]: 0.46; 95% confidence interval [CI]: 0.31-0.68). The protection data showed that smallpox vaccination effectively reduced the risk of severe monkeypox infection (RR: 0.61; 95% CI: 0.42-0.87). Third-generation vaccines showed greater efficacy (RR: 0.36, 95% CI: 0.22-0.56) than first-generation vaccines. The number of doses of smallpox vaccine has no significant effect on monkeypox. Safety data showed that adverse reactions after smallpox vaccination were mainly mild and included local erythema, swelling, induration, itching, and pain. Meanwhile, we found that smallpox vaccination could induce the production of neutralizing antibodies against monkeypox. Our findings offer compelling evidence supporting the clinical application of the smallpox vaccine for preventing monkeypox and advocate that high-risk groups should be prioritized for receiving one dose of the smallpox vaccine if the vaccine stockpile is low.

Increased human-to-human transmission of monkeypox virus (MPXV) is cause for concern, and antibodies directed against vaccinia virus (VACV) are known to confer cross-protection against Mpox. We used 430 serum samples derived from the Scottish patient population to investigate antibody-mediated cross-neutralization against MPXV. By combining electrochemiluminescence immunoassays with live-virus neutralization assays, we show that people born when smallpox vaccination was routinely offered in the United Kingdom have increased levels of antibodies that cross-neutralize MPXV. Our results suggest that age is a risk factor of Mpox infection, and people born after 1971 are at higher risk of infection upon exposure.

Since May 2022, several countries outside of Africa experienced multiple clusters of monkeypox virus (MPXV)-associated disease. In the present study, anti-MPXV and anti-vaccinia virus (VACV) neutralizing antibody responses were evaluated in two cohorts of subjects from the general Italian population (one half born before the WHO-recommended end of smallpox vaccination in 1980, the other half born after). Higher titers (either against MPXV or VACV) were observed in the cohort of individuals born before the interruption of VACV vaccination. An association between VACV and MPXV antibody levels was observed, suggesting that the smallpox vaccination may confer some degree of cross-protection against MPXV infection. Results from this study highlight low levels of immunity toward the assessed Orthopoxviruses, especially in young adults, advocating the introduction of a VACV- or MPXV-specific vaccine in case of resurgence of monkeypox disease outbreaks.

Monkeypox has been endemic in Congo and Nigeria for at least five decades. Since early May 2022, there have been numerous unprecedented outbreaks throughout the world in places without any previously reported cases. While a majority of the diagnosed cases have been within Europe and the Americas, several cases have occurred in non-endemic African countries. As of December 2022, 82,999 cases had been reported globally, prompting concern among the World Health Organization (WHO) members. While the WHO has not labeled this epidemic a Global Health Emergency, member states have begun to put forward plans to consolidate their emergency vaccine stockpiles and share the limited number of vaccines made by the single FDA-approved manufacturer, Bavarian Nordic. Many countries are concerned about how vaccines will be shared. Some of the larger donor States are positioned to be the biggest beneficiaries of vaccine sharing, while States from areas that have been suffering from the virus since the 1970s have not been allocated any. This pattern of vaccine distribution echoes that seen during the early part of the COVID-19 pandemic. Due to the similarities between Monkeypox and Smallpox, contact precautions and vaccination seem to be effective strategies to combat its rapid spread. We aim to evaluate how an eradication program model similar to that used for Smallpox can be applied to Monkeypox, and whether it can address vaccine inequity. To do this, we use a multi-pronged approach targeting disease surveillance, vaccine awareness, manufacturing, cost, and distribution strategies.

The smallpox infection with the variola virus was one of the most fatal disorders until a global eradication was initiated in the twentieth century. The last cases were reported in Somalia 1977 and as a laboratory infection in the UK 1978; in 1980, the World Health Organization (WHO) declared smallpox for extinct. The smallpox virus with its very high transmissibility and mortality is still a major biothreat, because the vaccination against smallpox was stopped globally in the 1980s. For this reason, new antivirals (cidofovir, brincidofovir, and tecovirimat) and new vaccines (ACAM2000, LC16m8 and Modified Vaccine Ankara MVA) were developed. For passive immunization, vaccinia immune globulin intravenous (VIGIV) is available. Due to the relationships between orthopox viruses such as vaccinia, variola, mpox (monkeypox), cowpox, and horsepox, the vaccines (LC16m8 and MVA) and antivirals (brincidofovir and tecovirimat) could also be used in the mpox outbreak with positive preliminary data. As mutations can result in drug resistance against cidofovir or tecovirimat, there is need for further research. Further antivirals (NIOCH-14 and ST-357) and vaccines (VACΔ6 and TNX-801) are being developed in Russia and the USA. In conclusion, further research for treatment and prevention of orthopox infections is needed and is already in progress. After a brief introduction, this chapter presents the smallpox and mpox disease and thereafter full overviews on antiviral treatment and vaccination including the passive immunization with vaccinia immunoglobulins.

Monkeypox virus (MPXV) of poxviridae family causes a zoonotic disease called monkeypox (Mpox). MPXV cases have a fatality ratio ranging from 0 to 11% globally and have been more prevalent in children. There are three generations of smallpox vaccines that protect against MPXV. First and second generation of the vaccinia virus (VACV) vaccine protects MPXV. However, various adverse side effects were associated with the first and second generations of vaccines. In contrast, the Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN) replication-incompetent vaccine shows fewer adverse effects and a significant amount of neutralizing antibodies in mammalian cells. A third-generation Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN) was approved to prevent Mpox in 2019. Recently, MVA-BN-based Imvanex, Imvamune, and JYNNEOS vaccines have also been administered against MPXV. Globally, the World Health Organization (WHO) declared a global health emergency in May 2022 due to increased MPXV cases. Various computational studies have also designed a multi-epitope-based vaccine against the MPXV. In the multi-epitope-based vaccine, different epitopes like B-cell, Cytotoxic T Lymphocyte (CTL), CD8+, and CD4+ epitopes were derived from MPXV proteins. Further, these epitopes were linked with the help of various linkers to design a multi-epitope vaccine against MPXV. In summary, we have provided an overview of the current status of the vaccine against MPXV.

Smallpox was a significant cause of mortality for over three thousand years, amounting to 10% of deaths yearly. Edward Jenner discovered smallpox vaccination in 1796, which rapidly became a smallpox infection preventive practice throughout the world and eradicated smallpox infection by 1980. After smallpox eradication, monkeypox vaccines have been used primarily in research and in outbreaks in Africa, where the disease is endemic. In the present, the vaccines are being used for people who work with animals or in high-risk areas, as well as for healthcare workers treating patients with monkeypox. Among all orthopoxviruses (OPXV), monkeypox viral (MPXV) infection occurs mainly in cynomolgus monkeys, natural reservoirs, and occasionally causes severe multi-organ infection in humans, who were the incidental hosts. The first case of the present epidemic of MXPV was identified on May 7, 2022, and rapidly increased the number of cases. In this regard, the WHO declared the outbreak, an international public health emergency on July 23, 2022. The first monkeypox vaccine was developed in the 1960s by the US Army and was based on the vaccinia virus, which is also used in smallpox vaccines. In recent years, newer monkeypox vaccines have been developed based on other viruses such as Modified Vaccinia Ankara (MVA). These newer vaccines are safer and can provide longer-lasting immunity with fewer side effects. For the future, there is ongoing research to improve the current vaccines and to develop new ones. One notable advance has been the development of a recombinant vaccine that uses a genetically modified vaccinia virus to express monkeypox antigens. This vaccine has shown promising results in pre-clinical trials and is currently undergoing further testing in clinical trials. Another recent development has been the use of a DNA vaccine, which delivers genetic material encoding monkeypox antigens directly into cells. This type of vaccine has shown effectiveness in animal studies and is also undergoing clinical testing in humans. Overall, these recent advances in monkeypox vaccine development hold promise for protecting individuals against this potentially serious disease.

Variola virus is an anthroponotic agent that belongs to the orthopoxvirus family. It is an etiological agent of smallpox, an ancient disease that caused massive mortality of human populations. Twentieth century has witnessed the death of about 300 million people due to the unavailability of an effective vaccine. Early detection is the primary strategy to prevent an outbreak of smallpox. Variola virus forms the characteristic pus-filled pustules and centrifugal rash distribution in the infected patients while transmission occurs mainly through respiratory droplets during the early stage of infection. No antiviral drugs are approved for variola virus till date. Generation of first-generation vaccines helped in the eradication of smallpox which was declared by the World Health Organization.
