According to the guidance of the Ministry of Health, there are 3 groups of subjects who are vaccinated with 4 doses of COVID-19 vaccine, who are 50 years old or older; people aged 18 years or older with moderate to severe immunodeficiency; people in high-risk groups exposed to COVID-19: health workers, frontline officials, workers in industrial zones. In these subjects, experts believe that the fourth shot has important protective significance.

TS.BS Pham Quang Thai – Head of the Northern Expanded Immunization Office, National Institute of Hygiene and Epidemiology, said: “The fourth dose of COVID-19 vaccine is especially valuable for the group of subjects with impaired immunity. epidemics, have underlying medical conditions, people with depleted status… Nose 4 has important protective significance”.

Doctor Do Quoc Phong – Deputy Head of Internal Medicine and Poison Control Department, Hospital E added: “Vaccines will be prioritized in the group of subjects with many high-risk factors, which are people with underlying medical conditions. such as diabetes, blood pressure or maintaining immunosuppressive drugs, or chronic obstructive pulmonary disease, cardiovascular disease … to avoid the risk of getting worse when infected with COVID-19”.

According to the instructions, the injection interval is at least 4 months after the 3rd dose; People who have contracted COVID-19 after receiving the 3rd dose should delay 3 months after contracting the disease. This is a suitable time based on the duration of antibody existence in the body, because after a certain time, this amount of antibodies will be lost, from which the ability to prevent epidemic also tends to decrease; especially in some groups with weak resistance.

Doctor Do Quoc Phong said: “Each person will have a different ability to copy and store data about the virus, as well as the existence of antibodies in each body. In the body, there is a decrease in some subjects. Therefore, it should be injected early when there is a decrease in antibody levels.”
