Dengue continues to be a significant public health concern, with cases surpassing 340,000 this year alone. With rising dengue cases, a second-generation vaccine is crucial for Filipinos, offering a more effective way to prevent the disease and supporting public health efforts amid lingering distrust after the 2018 Dengvaxia controversy.controversy.
“The second-generation dengue vaccine addresses issues previously associated with first generation vaccines,” explains Dr. Anna Ong-Lim, an infectious disease specialist. “With this new vaccine, there’s no longer a need to determine if a person has had dengue before getting vaccinated. It’s safe for both those who’ve had dengue before and those who haven’t.”
The new vaccine’s profile is a major step forward from the first-generation vaccine, which required healthcare providers to check for prior infection. Without this screening, those without a previous dengue infection, known as “seronegative” patients, faced a risk of developing severe dengue if vaccinated. However, the second-generation vaccine eliminates that concern, making immunization accessible without testing for past infection.
For Dr. Ong-Lim, the second-generation vaccine represents a powerful addition to existing dengue prevention strategies. She compares it to other preventive measures taken in infectious diseases, such as COVID-19, where vaccines complement practices like physical distancing. “In high-risk diseases, prevention options are critical. When you have the chance to lower your risk with a vaccine, it’s a valuable opportunity,” she notes.
While the vaccine may initially be available only in private healthcare settings, Dr. Ong-Lim believes this doesn’t diminish its significance. Like the chickenpox vaccine, which is available privately in the Philippines, the dengue vaccine can still provide crucial protection for those who choose to receive it.
Dr. Ong-Lim encourages people to discuss the vaccine with healthcare providers, emphasizing that a well-informed public will make better choices. “It’s essential to consult with your physician to understand the benefits and risks and get answers to any questions you may have,” she advises. “With better knowledge about the options available, individuals can make decisions with confidence.”
The Philippine Medical Association (PMA) has reaffirmed its commitment to strengthening vaccination efforts in the country, emphasizing the critical role of immunization in preventing vaccine-preventable diseases (VPDs) like dengue, measles, and mumps. The PMA urged the medical community to restore public trust in vaccines by relying on evidence, research, and data to promote accurate information and reassure patients about vaccine safety. Backing initiatives like the Department of Health’s “Oplan Balik-Eskwela” program, the PMA underscored the importance of vaccination for children and adults alike, alongside fostering trust in regulatory agencies to ensure vaccine efficacy and safety.
