Hello doctor,

I was tested positive for COVID five weeks ago. And by the third week, I was completely cured without any symptoms. But now, I have inflammation in my lungs. I consulted a doctor and took a chest x-ray; I was diagnosed with bronchitis.

I received the first Pfizer vaccine after I recovered from the initial symptoms. I am due for the second shot this week. I know that the vaccine can cause temporary flu-like symptoms. Is there any risk of causing more inflammation if I get the second shot this week?

Kindly help.



Welcome to

Thank you for the query.

I can understand your concern. According to your statement, you have been suffering from persistent dyspnea. You have been tested positive for COVID-19 (Coronavirus Disease-2019) five weeks ago. Your chest x-ray shows peribronchial cuffing with tracheobronchitis (attachments removed to protect the patient’s identity).

Inflammation of the trachea and bronchial tubes is known as tracheobronchitis that may result from viral or bacterial infections, irritants or allergens, cigarette smoking, and others. It is characterized by cough, fever, and purulent sputum.

As you have a history of becoming COVID positive, your tracheobronchitis is most probably a result of COVID-19 infections or a consequence or complication of COVID-19 disease.

Take your second dose of the COVID-19 vaccine in due time without any tension.

Take care.
