South Korea Prepares for Winter Flu Season with National Triple-Strain Vaccine Rollout – Breaking News
Seoul, South Korea – A significant shift in South Korea’s annual influenza vaccination strategy is underway. Starting later this month, the nation will begin administering a triple-strain flu vaccine, a change prompted by recommendations from the World Health Organization (WHO). This marks a departure from the previously used four-strain vaccine and signals a proactive approach to managing the upcoming winter flu season. This is a developing story, and archyde.com is committed to bringing you the latest updates as they unfold. This is a crucial update for anyone concerned about public health and seasonal illness prevention – a key area for health news.
What’s Changing with the Flu Vaccine?
For years, South Korea’s national influenza vaccination program utilized a quadrivalent (4-ga) vaccine, protecting against four different strains of the influenza virus: two type A strains (H1N1 and H3N2) and two type B strains (Victoria and Yamagata). However, the WHO recently advised prioritizing protection against the most prevalent strains, leading to the adoption of a trivalent (3-ga) vaccine that excludes the Yamagata-lineage B virus. This decision, while strategic, has also sparked competition among pharmaceutical companies.
Who is Eligible and When Can You Get Vaccinated?
The 2025-2026 seasonal influenza national vaccination campaign will run from later this month through April of next year. The rollout will prioritize those most vulnerable to severe complications from the flu, beginning with children aged 6 to 13. Following this, vaccinations will be offered to pregnant women and seniors aged 65 and older. Six vaccines will be supplied to the national vaccination program, including domestic options from GC Green Cross (“GC Flu”), Boryeong Biopharma (“Boryeong Flu Vaccine”), and SK Bioscience (“Sky Cell Flu”), alongside Sanofi’s Park Griffettra.
The Pharmaceutical Response: Competition Heats Up
The shift to a triple vaccine has triggered a flurry of activity within the pharmaceutical industry. Seven flu vaccines are slated for distribution in Korea this year, including imported options from CSL Seqirus, GlaxoSmithKline (GSK), Sanofi, and AstraZeneca. However, the change has also put pressure on vaccine pricing, with the cost of triple vaccines falling below 10,000 won. Despite this, companies are vying for a share of both the publicly funded national vaccination program and the private, non-paid vaccine market. Sanofi, in particular, is making a strong push into the elderly vaccine market with its ‘Efluida’ vaccine, challenging the dominance of CSL Seqirus’s ‘Fluad Quad.’
High-Dose Vaccines and a Nasal Spray Return
Experts are increasingly recommending high-capacity flu vaccines – containing roughly four times the antigen of standard doses – particularly for older adults, whose immune systems may not respond as robustly to traditional vaccines. Adding another layer of innovation, AstraZeneca’s nasal spray vaccine, ‘Flumist,’ is making a comeback in Korea after a decade-long absence. Initially introduced in 2009, Flumist is expected to be popular among children and adolescents, offering a needle-free alternative. This resurgence highlights the ongoing evolution of flu prevention strategies.
Beyond the Headlines: Understanding Flu Vaccine Efficacy
Flu vaccines aren’t perfect, and their effectiveness can vary from year to year depending on how well the vaccine strains match circulating viruses. However, vaccination remains the most effective way to reduce your risk of contracting the flu and experiencing severe complications. Staying informed about the latest recommendations from health authorities like the WHO and the Korea Centers for Disease Control and Prevention is crucial for making informed decisions about your health.
