National Institute of Vaccines Advances “Avian Influenza Vaccine” Development
Despite the absence of widespread outbreaks in thailand, proactive measures are underway to develop vaccines and prepare for potential domestic epidemics. The Director of the National Vaccine Institute recently provided updates on collaborative efforts to develop an “avian influenza vaccine.”
mRNA Vaccine Research and Development
The National Vaccine Institute is funding research and development of an H5N1 mRNA avian influenza vaccine at Chulalongkorn University. initial testing in mice has shown promising results, effectively stimulating immunity. Current studies involve larger animals, specifically ferrets, which are highly susceptible to influenza viruses. These challenge tests involve vaccinating the animals and then exposing them to the virus to assess their resistance.
Expert Insights on Pandemic Preparedness
According to the Director of the National Vaccine Institute, Dr. Nakorn Premsri, there is no immediate indication of a major epidemic in Thailand.Though, vigilance and vaccine development remain crucial. He stated:
“ไข้หวัดนกH5N1 อัตราการเสียชีวิตสูง จึงต้องมีการเตรียมความพร้อมในการรับมือ ซึ่งหากไข้หวัดนกระบาดใหญ่จะเหนื่อยกว่าตอนโควิด-19ระบาดมาก แม้ว่าเชื้อที่คนติดแล้วเจ็บป่วยรุนแรงมักจะไม่ระบาดใหญ่ แต่ก็จะมีโอกาสเกิดขึ้นเพราะเชื้อไข้หวัดใหญ่กลายพันธุ์ได้ง่าย ถ้ากลายพันธุ์ไปในทางที่รุนแรงน้อยลง เช่น จากอัตราเสียชีวิต 40 % แล้วเหลือ 4 % น้อยลง 10 เท่าก็เป็นอัตราที่น่ากลัวแล้ว เพราะโควิด-19 อยู่ที่ 2-4 % แต่ตอนนี้ยังไม่มีสัญญาณก็ต้องเฝ้าระวัง”
dr. Nakorn Premsri, Director of the National vaccine Institute
This highlights the critical need for preparedness due to the high mortality rate associated with H5N1 and the potential for influenza viruses to mutate.
Collaboration with the Government Pharmaceutical Organization (GPO)
The National Vaccine Institute is also collaborating with the Government Pharmaceutical Organization (GPO) to explore new vaccine production technologies that do not rely on chicken eggs. This is crucial because an avian influenza outbreak could disrupt egg supplies, hindering vaccine production.
Thailand Enhances Influenza Preparedness with Local Vaccine Progress
Strategies focus on vaccine research and development to combat potential outbreaks, especially avian influenza (H5N1). This article explores Thailand’s proactive measures, including mRNA vaccine research, collaboration with the Government Pharmaceutical Association (GPO), and expert insights from the National Vaccine Institute.
National Vaccine Institute Advances “Avian Influenza Vaccine” Development
Despite the absence of widespread H5N1 outbreaks in Thailand, proactive measures are underway to develop vaccines and prepare for potential domestic epidemics. The Director of the National Vaccine Institute recently provided updates on collaborative efforts to develop an “avian influenza vaccine.” These efforts are critical to safeguarding public health and ensuring national security in the face of emerging infectious disease threats.
mRNA Vaccine Research and Development
The National Vaccine institute is funding research and development of an H5N1 mRNA avian influenza vaccine at Chulalongkorn University. Initial testing in mice has shown promising results, effectively stimulating immunity. Current studies involve larger animals, specifically ferrets, wich are highly susceptible to influenza viruses. These challenge tests involve vaccinating the animals and then exposing them to the virus to assess their resistance. The mRNA technology offers potential advantages in terms of speed of development and production scalability compared to traditional vaccine methods.

Nakorn Premsri, Director of the National Vaccine Institute
This highlights the critical need for preparedness due to the high mortality rate associated with H5N1 and the potential for influenza viruses to mutate. Even a mutation that reduces mortality tenfold from 40% to 4% would still be a critically important threat, exceeding the mortality rate of COVID-19.
collaboration with the Government Pharmaceutical Organization (GPO)
The National Vaccine Institute is also collaborating with the Government Pharmaceutical Organization (GPO) to explore new vaccine production technologies that do not rely on chicken eggs. This is crucial because an avian influenza outbreak coudl disrupt egg supplies, hindering vaccine production. Cell-based vaccine production and other alternative technologies are being investigated to ensure a stable vaccine supply in the event of a pandemic.
Thailand’s Pandemic Preparedness: Key Strategies
Thailand’s comprehensive pandemic preparedness plan includes several key strategies:
- Surveillance and Early Detection: Strengthening surveillance systems to detect and monitor influenza strains and potential outbreaks.
- Vaccine Development and Production: Investing in research and development of novel vaccines,including mRNA vaccines,and diversifying vaccine production methods.
- Antiviral Stockpiles: Maintaining adequate stockpiles of antiviral medications for treatment and prophylaxis.
- Public Health Measures: Implementing non-pharmaceutical interventions such as mask-wearing, social distancing, and hand hygiene during outbreaks.
- Risk Dialog: Communicating effectively with the public about the risks of influenza and the importance of preventive measures.

| Feature | Traditional Vaccine Production (Egg-Based) | mRNA vaccine Production |
|---|---|---|
| Production Time | Months | Weeks |
| Scalability | Limited by egg supply | Highly scalable |
| Adaptability to New Strains | Slower adaptation | Faster adaptation |
| Reliance on Biological Materials | Requires chicken eggs | Synthetically produced |
Frequently Asked Questions (FAQ) about Influenza Preparedness in Thailand
What is Thailand doing to prepare for future influenza pandemics?
Thailand is actively engaged in several key initiatives to prepare for future influenza pandemics. These include:
- Investing in research and development of novel vaccine technologies, such as mRNA vaccines, being developed at Chulalongkorn university.
- Collaborating with the Government Pharmaceutical Organization (GPO) to explore alternative vaccine production methods that do not rely on chicken eggs.
- Strengthening surveillance systems to detect and monitor emerging influenza strains and potential outbreaks.
- Maintaining stockpiles of antiviral medications.
- Implementing public health measures and risk communication strategies to inform and protect the public.
Why is Thailand focusing on mRNA vaccine technology for influenza?
mRNA vaccine technology offers several advantages over traditional vaccine production methods:
- Faster development Time: mRNA vaccines can be developed and manufactured more quickly than traditional vaccines.
- Scalability: mRNA production is highly scalable, allowing for rapid production of large quantities of vaccine during a pandemic.
- Adaptability: mRNA vaccines can be easily adapted to target new and emerging influenza strains.
- Reduced Reliance on Biological Materials: mRNA vaccines are synthetically produced,reducing reliance on biological materials such as chicken eggs.
What is the role of the Government Pharmaceutical Organization (GPO) in Thailand’s pandemic preparedness?
The GPO plays a crucial role in Thailand’s pandemic preparedness by:
- Collaborating with the National Vaccine Institute to explore alternative vaccine production technologies.
- Manufacturing and distributing vaccines and antiviral medications.
- Ensuring a stable supply of essential medicines during a pandemic.
What are the potential risks of an avian influenza outbreak in Thailand?
An avian influenza outbreak in Thailand could pose several significant risks:
- Public Health Threat: Avian influenza viruses, such as H5N1, can cause severe illness and death in humans.
- Economic Impact: Outbreaks can disrupt the poultry industry and lead to economic losses.
- Strain on Healthcare System: A widespread outbreak could overwhelm the healthcare system.
- Disruption of Vaccine Production: Reliance on egg-based vaccine production could be disrupted if an outbreak affects chicken populations.
What is the mortality rate of H5N1 avian influenza?
H5N1 avian influenza has a high mortality rate in humans. While the exact figures can vary depending on the specific strain and the population affected, the WHO states that around 50% of confirmed human cases of H5N1 avian influenza have been fatal.This highlights the importance of preparedness efforts against this virus.
