Response:
Given your father's underlying respiratory condition, persistent cough, and chest discomfort, he should first seek medical evaluation at a healthcare facility. A doctor will assess his respiratory and cardiovascular function, and may order a blood oxygen saturation (SpO₂) test if necessary.
It is important to understand that the respiratory syncytial virus (RSV) vaccination does not treat underlying medical conditions. Therefore, the doctor will advise on an appropriate vaccination schedule once his acute symptoms have stabilized.
RSV circulates year-round, with incidence typically increasing in Vietnam during transitional seasons and the rainy season. RSV has two main groups, A and B, and spreads through respiratory droplets. While it causes cold-like symptoms after four to six days, it can progress to severe pneumonia or bronchitis in older adults with underlying health issues. Seniors should consider getting vaccinated in the summer or before the rainy season to allow their bodies to develop protective immunity.
Hot weather often leads to increased air conditioner use, which can dry out respiratory mucous membranes, making them more susceptible to RSV infection. The risk of pathogen transmission also rises during travel or in crowded places.

Currently, there is no specific antiviral treatment for RSV. Doctors focus on supportive care and managing complications for each patient. Therefore, prevention remains crucial.
Vaccination is a recommended measure for older adults to reduce the risk of illness and severe complications. Available RSV vaccines for adults aged 60 and above include Arexvy (GSK, UK) and Abrysvo (Pfizer, US). Both are recombinant protein vaccines, administered as a single dose after a screening examination.
In addition to full vaccination, seniors should maintain preventive measures such as frequent hand hygiene, practicing respiratory etiquette, and limiting close contact with individuals exhibiting cold symptoms. Avoid sharing personal items and food. If close contact is unavoidable, use a mask or appropriate protective measures. When someone in the household has a cough, fever, or runny nose, increase room ventilation and disinfect frequently touched surfaces. Limit close contact between sick young children and older adults. Furthermore, maintaining a balanced diet and undergoing regular health check-ups are essential for effectively managing underlying medical conditions.
