Valneva Enhances Chikungunya Vaccine ACIP Guidelines for Travelers
Valneva's Chikungunya Vaccine IXCHIQ and ACIP Updates
Valneva SE, recognized for its innovative vaccine solutions, has announced a pivotal update regarding its chikungunya vaccine IXCHIQ. During a routine meeting, the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) provided new guidance on the use of this vaccine, especially for U.S. travelers. With the rise of chikungunya outbreaks globally, this recommendation holds great significance for public health.
ACIP Recommendations and Guidelines
As per the latest ACIP meeting, IXCHIQ now has a reaffirmed recommendation for individuals aged 18 and older who are traveling to regions experiencing chikungunya outbreaks. Additionally, ACIP suggests that the vaccine may also be appropriate for those planning to stay in areas with a heightened risk of chikungunya, even if an outbreak has not been reported, particularly for extended trips lasting six months or more. These updates showcase the commitment to prioritize health and safety for U.S. travelers.
Precaution for Older Adults
The ACIP also advised increased caution for individuals aged 65 and older. This decision comes on the heels of an ongoing investigation into reported severe adverse events among this age group following IXCHIQ vaccination. Although only a few cases have been documented through the Vaccine Adverse Event Reporting System (VAERS), including hospitalizations, all patients had underlying health conditions that may have contributed to their severe reactions.
Commitment to Safety and Ongoing Monitoring
Juan Carlos Jaramillo, M.D., the Chief Medical Officer at Valneva, expressed the company's dedication to safety. He indicated that the safety profile of IXCHIQ remains favorable, and the company respects ACIP's recommendation. Valneva is keen to ensure that healthcare providers assess each patient’s medical history and travel plans before administering the vaccine, emphasizing the importance of a thorough evaluation.
Valneva's Role in Managing Chikungunya
In response to the chikungunya outbreaks, Valneva has taken proactive steps to supply vaccines to areas in need. Notably, in recent weeks, they delivered 40,000 doses of IXCHIQ to France's La Réunion Island. The local public health agency has identified adults aged 65 and over, especially those with pre-existing conditions, as a priority group for vaccination to curb the ongoing outbreak effectively. Additionally, Valneva will provide an extra 50,000 doses to assist ongoing health initiatives.
Global Supply and Safety Monitoring
To date, Valneva has distributed approximately 80,000 doses of IXCHIQ across the U.S., Canada, and Europe. Since January 2025, no significant adverse events have been reported globally. Valneva's commitment to safety is showcased in their ongoing post-marketing surveillance, which includes routine safety reports to the U.S. Food and Drug Administration (FDA).
Understanding Chikungunya: The Threat
Chikungunya virus (CHIKV) is a dengue-like viral infection spread by Aedes mosquitoes. Symptoms often include high fever, debilitating joint pain, and other flu-like symptoms. Since it first surged in the early 2000s, chikungunya has posed a significant public health challenge, affecting millions across the globe. Given the establishment of CHIKV in over 110 countries, the WHO identifies it as a noteworthy concern, especially with rising global temperatures expanding mosquito habitats and increasing transmission rates.
Valneva's Vision and Impact on Global Health
Valneva SE is at the forefront of the vaccine industry, focusing on unmet medical needs through advanced research and development. Their portfolio includes the world’s first chikungunya vaccine, and a commitment to pushing the boundaries of vaccine technology.
