Prof. Yongphu Worawan, Head of the Center of Specialization in Clinical Virology Faculty of Medicine Chulalongkorn University Private Facebook post Dr. Yong Phu Worawan, MD. About the protection level of the COVID-19 vaccine Which judging the effectiveness of the vaccine Will be talked about the level of disease prevention. It is very difficult for asymptomatic patients to evaluate the vaccine because not all cases are tested. Or randomly testing the infection periodically Most will focus on when symptoms are up or need to go to hospital.
Norway rises 29 dead after getting Pfizer’s coronavirus vaccine, most of them elderly.
But for the COVID-19 vaccine Currently used Defenses are divided into
1. Prevent infection, will not spread disease, or cause illness.
2. Prevent disease. It doesn’t protect against infection, it won’t be a disease, but it may be contagious.
3. Reduce the severity of the disease. It does not prevent infection, is a disease but is not severe, does not enter the hospital, does not die.
The current COVID-19 vaccine. This will prevent the occurrence of the disease, reduce the symptoms of the disease and not die. Prevention studies have not been conducted. When given vaccines, they can become infected. How likely is the infection to spread the disease?
So when the COVID-19 vaccine Can reduce the severity Reduce hospitalization Was satisfied to some extent Waiting for education on how much infection is prevented. Education must be done and detailed, difficult to follow. But if the infection has no symptoms That is, everyone must be tested for infection. Signs from the neck come to compare each other so you will know.
Meanwhile From past studies The effectiveness of the vaccine comes in the form of prevention. Reduce the severity of the disease Reduce symptoms of disease, not having to go to hospital Or if it is, have the least symptoms Most recent studies have not looked at infection prevention or the prevention of asymptomatic infection.
Therefore, the vaccination now Therefore focus on reducing the severity of the disease The group of people who are now vaccinated are at risk of serious disease and death have to wait and see for future information. If the vaccine can prevent infection Even without symptoms Vaccination will also focus on those who will be asymptomatic but infectious. Or those who are young enough
Research studies on the COVID-19 vaccine It is currently incomplete and completed. Because I want to use it first Need specific information before All details will have to be analyzed and further studied in the long run.
“It is believed that in the near future there will be new information coming out. As new information becomes available, vaccination strategies may change, for example, easily infecting people of labor age and spreading them to others.
So now from “Current information” The group that should be vaccinated is therefore at risk of developing severe disease. Rather than in those that are more easily spread, such as in adolescence Healthy labor age
