“Mo Yong” reveals the reason why Thailand does not import The vaccine is a nasal spray. Although it is very convenient to use because I learned a lesson from the flu

(22 Nov. 21) Prof. Dr. Yong Phuworawan Head of the Center of Specialization in Clinical Virology, Department of Pediatrics Faculty of Medicine Chulalongkorn University Posted on Facebook, Yong Poovorawan, saying: Covid-19 vaccine, live vaccine, nasal spray, lessons from flu.

In the 2009 influenza outbreak, Thailand is preparing to develop a live attenuated influenza vaccine. The bacteria are sensitive to high temperatures. when sprayed into the nose It will only infect the nasal cavity and cannot go down into the lungs. Because it can’t stand the body temperature of 37 degrees in the body. The infection will stimulate immunity to influenza. very well as infectious in nature

That year, Thailand received technology transfer from Russia. and try to develop Influenza The St. Petersburg breed is still well remembered and does not go anywhere. because it was made It does not serve the purpose of preventing illness and death. The Pharmaceutical Organization changed to a lethal infection later. And the one used today in Thailand is a dead infection.

meanwhile There is also a seasonal flu vaccine. The nasal spray used in the United States and in the West is called FluMist of MedImmune. Use a nasal spray. This virus is not heat resistant. inability to enter the lungs

because it is an infection therefore cannot give in people with weak immunity such as young children under 2 years old, the elderly over 50 years old, people who take immunosuppressant drugs People with chronic diseases, pregnant women, those who take aspirin, because they will cause Reye syndrome, in conclusion, it is at risk of influenza and will be dangerous as life-threatening pneumonia can’t give Only for the strong that the disease is not severe

in practice Using the influenza vaccine We will focus on preventing such risk groups. that when influenza is life-threatening If the vaccine is only available to healthy people, especially in adolescents therefore contrary to reality In the aim of vaccinating influenza in Thailand wanting to reduce morbidity and mortality

Likewise, the development of a COVID-19 vaccine if the virus is alive. various indications must be similar especially in people with low immunity for fear that this virus will spread taboo in people with low immunity, the elderly, pregnant women People with chronic diseases, young children, who are all at risk of COVID-19, the nasal spray vaccine can only be used by healthy individuals. like the flu nasal spray vaccine. will not benefit at all Because those people who are infected with covid-19 are not severe, the chance of hospitalization or death is very low.

Weaknesses of the influenza nasal spray vaccine for that reason therefore not used in Thailand Although it is very convenient to use
