The FIRST FDA-Approved and ACIP-Recommended Mpox Vaccine1,2

AGAINST MPOX WITH JYNNEOS*

*Vaccination with JYNNEOS may not protect all recipients.

ABOUT MPOX*

Mpox is a vaccine-preventable, viral disease that can cause symptoms such as a painful rash, fever, and swollen lymph nodes and can result in serious complications.3

There are 2 distinct clades4:

Clade
I

Found mainly in
Central Africa

Clade
II

Clade IIa found mainly in West Africa; Clade IIb found worldwide

Symptoms, complications, and mortality vary between the different clades.4,5

THERE WAS AN UNPRECEDENTED GLOBAL MPOX OUTBREAK IN 2022 (CAUSED BY
CLADE IIb STRAIN)3 — AND IT HASN’T GONE AWAY6†

  • Most common presentation: systemic illness, including fever and myalgia5
  • Characteristic rash, with papules that evolve to vesicles, pustules, and crusts in the genital, anal, or oral regions, and often involve the mucosa5
  • Infections with Clade IIb are rarely fatal (>99% of people who get this form of the disease are likely to survive)8
  • Up to 40% of cases had complications requiring medical treatment, and 1-13% required hospital admission for treatment or isolation5

Anyone can be infected by the mpox virus3; however, since 2022, most cases in the US have been among at-risk groups7,9

The ACIP recommends mpox vaccination for all at-risk individuals aged
≥18 years old.2

Persons at risk include2:

  • Gay, bisexual, and other men who have sex with men, transgender or nonbinary people who in the past 6 months have had one of the following:
    • A new diagnosis of ≥1 sexually transmitted diseases
    • More than one sexual partner
    • Sex at a commercial sex venue
    • Sex in association with a large public event in a geographic area where mpox transmission is occurring
  • Sexual partners of persons with the risks described in above
  • Persons who anticipate experiencing any of the above

Most at-risk people are still not fully vaccinated against mpox

There are ~2 million at-risk individuals eligible for mpox vaccination in the US11

As of January 2024, more than half of at-risk individuals are completely unvaccinated12‡

The risk for future mpox outbreaks in the US remains.13 Don’t wait for another surge.

If your patient is at risk for mpox, consider vaccination.

*The CDC, HHS, and WHO adopted “mpox” as the term used to refer to monkeypox disease on November 28, 2022.14
The mpox outbreak continues in most WHO regions, at a low level of transmission in the Western Pacific and South-East Asia, while more extensive transmission is observed in the European Region and in the Region of the Americas (as of December 22, 2023).6
US mpox vaccine administration data no longer being tracked as of January 10, 2024.12

Effectiveness Data

Vaccine effectiveness was inferred from clinical immunogenicity data and supported by data from animal challenge studies.15

Study 7 – a randomized, open-label study conducted at US military facilities in South Korea15

Study design: Healthy, smallpox vaccine-naive adults aged 18-42 years (N=433) received either 2 doses of JYNNEOS (n=220) administered 28 days apart or 1 dose of ACAM2000® (Smallpox [Vaccinia] Vaccine, Live) (n=213).

Primary endpoint: Geometric mean titer (GMT) of vaccinia-neutralizing antibodies assessed by Plaque Reduction Neutralization Test (PRNT) at “peak visits” defined as 2 weeks after second dose of JYNNEOS and 4 weeks after single dose of ACAM2000.

Peak visit neutralizing antibody responses induced by JYNNEOS were non-inferior to those elicited by ACAM2000.

Comparison of Vaccinia-Neutralizing Antibody Responses Following Vaccination with JYNNEOS or ACAM2000 in Healthy Smallpox Vaccine-Naïve Adults 18 Through 42 Years of Age, Study 7,
Per Protocol Set for Immunogenicity

*Non-inferiority of the “peak visit” PRNT GMT for JYNNEOS compared to ACAM2000 was demonstrated as the lower bound of the 1-sided 97.5% CI for the GMT ratio (JYNNEOS/ACAM2000) was >0.5.

Animal Challenge Studies

Efficacy of JYNNEOS to help protect cynomolgus monkeys (Macaca fascicularis) against a mpox virus challenge was evaluated in several studies15

Animals were given either placebo or JYNNEOS subcutaneously on Days 0 and 28. Animals were challenged with MPXV on Day 63.

Across all studies, 80-100% of JYNNEOS-vaccinated animals survived compared to 0-40% of control animals.

Real-world Effectiveness

Data from 3 case-control studies suggest the vaccine effectiveness of JYNNEOS against mpox ranges from 66-89% for full (2 doses) vaccination.16,17

  • CDC Epic Cosmos study: US patient records from Cosmos, an electronic health record platform
  • CDC multi-jurisdictional study: 12 US jurisdictions’ probable and confirmed mpox case lists
  • New York State study: case surveillance data and New York State’s (excluding New York City) immunization registry

Vaccine effectiveness in Epic Cosmos case-control study adjusted for age, race/ethnicity, social vulnerability index, and immunocompromising conditions. Cases/controls matched on week of index event, HHS region, gender identity. Vaccine effectiveness in multi-jurisdictional case-control study adjusted for age, race/ethnicity, immunocompromised status, reported close contact with a confirmed/suspected mpox case in 3 weeks prior to index event. In the New York State case-control study, conditional logistic regression model was adjusted for diagnosis week, race, age, region within state.

LIMITATIONS: These case-control studies included individuals vaccinated via subcutaneous, intradermal, and heterologous routes of administration. The studies were at risk for selection bias, confounding bias, and misclassification bias. Additional studies are needed.

Approved route of administration for JYNNEOS is subcutaneous. Emergency Use Authorization for intradermal administration was issued by FDA on August 9, 2022.1

ADVERSE REACTIONS

The overall clinical trial program included 22 studies and a total of 7,859 individuals aged 18-80 years who received at least 1 dose of JYNNEOS (7,093 smallpox vaccine-naïve and 766 smallpox vaccine-experienced individuals).15

Adverse Reactions – Study 1

Study 1 was a randomized, double-blind, placebo-controlled study conducted in the US in which vaccinia-naïve adults ages 18 to 40 years received either 2 doses of JYNNEOS (N=3003), or 2 injections of Tris-Buffered Saline (placebo, N=1002) 4 weeks apart.

Percentages of Subjects with Solicited Local Injection Site Reactions and Systemic Adverse Reactions within 8 Days of Administration of Any Dose of JYNNEOS in Adults 18 to 40 Years of Age, Study 1

*Grade 3 pain defined as spontaneously painful.
Grade 3 itching, muscle pain, headache, fatigue, nausea, and chills defined as preventing routine daily activities.
Fever defined as oral temperature ≥100.4°F (≥38°C), Grade ≥3 fever defined as ≥102.2°F (≥39.0°C).

Real-world Safety data

Data collected from multiple CDC vaccine safety monitoring systems (90% of VAERS reports were submitted in 2022) have identified no new or unexpected safety concerns with JYNNEOS.16

  • Most commonly reported adverse reactions to VAERS have been injection site symptoms (redness, swelling, pain, itching)16
  • The frequencies of local and systemic reactions reported are similar to those reported in clinical trials16
  • Myocarditis and pericarditis are adverse events of special interest. Observed rates are consistent with expected background rates16
  • No reported cases of progressive vaccinia, eczema vaccinatum, or blindness18
  • No recommended restrictions on blood or organ donation15

LIMITATIONS: Data based on voluntary reports through safety monitoring systems; not all potential reactions are captured. Estimations of frequency or establishment of causation may not be possible.

Dosing & Administration

Help protect your appropriate patients against mpox in 2 shots

JYNNEOS is administered in 2 doses given 4 weeks apart.15

HOW SUPPLIED

PACKAGING information

*An FDA-assigned 10-digit NDC is converted by healthcare systems/payers to the HIPAA-standardized 11-digit NDC format by adding a leading zero to the applicable short segment. The HIPAA conversion for JYNNEOS is 50632-0001-03 and 50632-0001-02 (new zero underlined and highlighted). When submitting an insurance claim, it is generally recommended to use the NDC that is printed on the package of the medication. Please check with your insurance provider to confirm any specific requirements or preferences they may have regarding the submission of NDC information with your claim.

Storage conditions

Store JYNNEOS frozen at -13°F to 5°F (-25°C to -15°C) and in the original package to protect from light. Once thawed, the vaccine may be kept at 36°F to 46°F (2°C to 8°C) for 4 weeks.15

Do not refreeze a vial once thawed. Do not use the vaccine after the expiration date shown on the vial label.15

For medical inquiries about JYNNEOS, please contact Medical Information at (844) 422-8274 or medical.information_na@bavarian-nordic.com.

JYNNEOS is approved for the prevention of smallpox and monkeypox disease in adults 18 years of age and older determined to be at high risk for smallpox or monkeypox infection.

Appropriate medical treatment must be available to manage possible anaphylactic reactions following administration of JYNNEOS. Anyone who has experienced a severe allergic reaction following a previous dose of JYNNEOS or following exposure to any component of JYNNEOS may be at increased risk for severe allergic reactions.

Syncope (fainting) has been reported following vaccination with JYNNEOS. Procedures should be in place to avoid injury from fainting.

Immunocompromised persons, including those receiving immunosuppressive therapy, may have a diminished immune response to JYNNEOS.

Vaccination with JYNNEOS may not protect all recipients.

In smallpox vaccine-naïve healthy adults, the most common (>10%) solicited injection site reactions were pain (84.9%), redness (60.8%), swelling (51.6%), induration (45.4%), and itching (43.1%); the most common solicited systemic adverse reactions were muscle pain (42.8%), headache (34.8%), fatigue (30.4%), nausea (17.3%) and chills (10.4%).

In healthy adults previously vaccinated with a smallpox vaccine, the most common (>10%) solicited injection site reactions were redness (80.9%), pain (79.5%), induration (70.4%), swelling (67.2%), and itching (32.0%); the most common solicited systemic adverse reactions were fatigue (33.5%), headache (27.6%), and muscle pain (21.5%).

The frequencies of solicited local and systemic adverse reactions among adults with HIV infection and adults with atopic dermatitis were generally similar to those observed in healthy adults.

Across all studies, a causal relationship to JYNNEOS could not be excluded for 4 serious adverse events (SAEs), all non-fatal, which included Crohn’s disease, sarcoidosis, extraocular muscle paresis and throat tightness.

Cardiac adverse events of special interest (AESIs) considered causally related to study vaccination were reported in 0.08% of subjects who received JYNNEOS and included tachycardia, electrocardiogram T wave inversion, electrocardiogram abnormal, electrocardiogram ST segment elevation, electrocardiogram T wave abnormal, and palpitations. None of the cardiac AESIs considered causally related to study vaccination were considered serious.
