Effectiveness of Mpox Vaccination and High-Risk Group Awareness in Preventing Monkeypox Spread: A Recent Study

Mpox Vaccination And High-Risk Group Awareness: A Significant Reduction in Mpox Cases

A recent study published in the eClinicalMedicine Journal employed a risk-structured susceptible-exposed-infectious-asymptomatic-recovered-vaccinated (SEIARV) modeling approach to assess the effectiveness of mpox vaccination and high-risk group awareness in preventing the spread of monkeypox (Mpox) in the United States. The study found that the combination of these two interventions resulted in a significant reduction of 64% in reported mpox cases and infections by the end of 2022.

The research utilized the JYNNEOS(R) vaccine for the mpox vaccination and focused on raising awareness in high-risk groups. The study suggests a synergistic effect between vaccination and high-risk group awareness in preventing the spread of mpox. The insights gained from the study are expected to be of great value for preparing for subsequent mpox epidemics and could also be relevant to other reemerging infectious diseases.

Combined Vaccination Efforts and High-Risk Group Awareness

The deterministic SEIARV model used in the study provided a comprehensive assessment of the effectiveness of preventive responses against mpox in the U.S. The JYNNEOS vaccine demonstrated high effectiveness at both the individual and population level. The study also highlighted the importance of changes in risky sexual behavior by high-risk groups. The combination of vaccination and high-risk group awareness almost successfully controlled the mpox epidemic in the U.S, averting 64% of US mpox cases.

Smaller Doses of Mpox Vaccine Elicit Equal Immune Response

The study also looked into the immune response elicited by smaller doses of the mpox vaccine in people living with and without HIV. The immune response was measured by the amount of detectable immunoglobulin G (IgG) antibodies. The study found that people living with HIV are at a higher risk of contracting mpox, but the immune response between vaccinated people living with HIV and vaccinated people who are HIV-negative did not show significant differences. It concluded that smaller vaccine doses of mpox vaccine administered in 2 doses, spread out over weeks to months, were similar to the full subcutaneous FDA-approved dose.

Lessons Learned from the Mpox Outbreak Response

The response to the mpox outbreak in the U.S offered several lessons, including the importance of community engagement, flexible public health responses, and investments in public health infrastructure. These factors are crucial in preventing a resurgence of the virus. The study underscores the need for ongoing attention to these issues and continued work in these areas.

Acceptance of Mpox Vaccine Among Healthcare Workers

Healthcare workers represent a high-risk group for mpox infection. A systematic review and meta-analysis examined the acceptance of the mpox vaccine among healthcare workers in the United States, providing valuable insights into the impact of mpox vaccination on this high-risk group.

The effectiveness of the mpox vaccination and the awareness among high-risk groups have shown promising results in controlling the epidemic. With the insights from this study, further research can focus on developing more effective strategies to tackle mpox, with potential relevance for other reemerging infectious diseases as well.
