Seasonal Immunizations: An Essential Part of Lung Disease Management

Late September heralds the arrival of autumn and marks the official start of the dreaded fall-through-winter cold and flu season. Now’s the perfect time to schedule your yearly immunizations against vaccine-preventable respiratory infections. 

At Fivestar Pulmonary Associates in Allen, McKinney, and Plano, Texas, our team strongly recommends routine seasonal vaccinations as a key preventive measure for all our patients managing chronic lung disease. Here’s why. 

Chronic lung disease can obstruct or restrict your breathing

Living with a chronic lung disease means having to deal with some degree of airway narrowing and/or low pulmonary function that makes breathing more difficult. Every day, our team helps patients manage long-term lung conditions like:

• Asthma (e.g., allergic, non-allergic, and eosinophilic types)
• COPD (encompassing chronic bronchitis and emphysema)
• Interstitial lung disease (e.g., pulmonary fibrosis, sarcoidosis)
• Bronchiectasis (recurrent airway damage and inflammation) 
• Cystic fibrosis (fills the airway with very thick, sticky mucus) 
• Pulmonary hypertension (high blood pressure in lung arteries)

Most chronic lung diseases involve inflammatory pathways, lung tissue damage, limited oxygen exchange, or all the above. 

Depending on the nature and severity of your condition, you may wheeze, cough, and feel tired or short of breath most of the time, or you may breathe easily until something triggers a symptom flare. 

Lung disease is a high-risk category for respiratory illness 

No matter the type of lung condition, all of them carry an elevated risk of severe illness from respiratory infections such as the common cold or influenza.

In fact, having chronic lung disease, whether it’s mild asthma or long-standing COPD, places you in the high-risk respiratory infection/illness category, meaning you’re more likely to experience:

• Severe and/or prolonged illness
• Secondary illness (e.g., pneumonia)
• Serious breathing symptom flares
• Irreversible lung tissue damage 
• Hospitalization and possible death 

This is why immunization against vaccine-preventable respiratory infections — from the seasonal flu and COVID-19 to RSV and bacterial pneumonia — is an essential part of every chronic lung disease management plan. 

Airway infection and lung disease: A dangerous combination

Having a chronic lung disease means your airway is already subject to some degree of sensitivity, swelling, damage, and excess mucus. By itself, this lower initial baseline can make it harder to fight off any respiratory infection you encounter. 

And when an infectious respiratory illness — like a cold, the flu, or RSV — does take hold, it causes a precarious chain reaction that amplifies airway inflammation, increases swelling, mucus, and airflow blockage, and triggers dangerous drops in blood oxygen levels. 

Common collisions between respiratory infection and chronic lung disease include: 

COPD and the flu or pneumonia

Having the flu or pneumonia on top of COPD can easily lead to trapped air, or old air you can’t fully exhale, leaving less room for fresh air and increasing your likelihood of severe oxygen drops and life-threatening respiratory failure.

Asthma and a cold or flu infection

Even a mild cold or flu infection can impede your airway and trigger a life-threatening asthma attack; in fact, viral infections are responsible for up to 85% of severe asthma exacerbations.

Bronchiectasis and bacterial pneumonia 

Damaged airways and excess mucus trap bacteria, giving rise to persistent, lung-damaging infection cycles and ongoing respiratory distress. 

Pulmonary hypertension and RSV

When you have pulmonary hypertension, coming down with RSV or any other respiratory infection places increased strain on your heart, triggering a swift escalation of symptoms such as shortness of breath and putting you at risk for low blood oxygen levels and rapid heart failure. 

Protect your lungs and breathe easy with targeted vaccines

Luckily, keeping up with recommended immunizations can go a long way in protecting you from the serious respiratory harms posed by catching a seasonal bug when your airway is already under the strain of a chronic lung disease. 

Simply put, seasonal immunizations are a vital defense tool against infection, illness, and worsening lung disease. Every year, most high-risk lung disease patients should get:

• A flu shot to protect against current circulating strains
• A COVID-19 booster to protect against newer variants
• An RSV shot to guard against respiratory syncytial virus

Getting these three vaccines every autumn can significantly reduce your risk of serious illness, severe symptom flares, hospitalization, lung damage, and secondary pneumonia. Aim to get your shots early (in September or October) before virus levels peak.

And, if you haven’t already gotten them, two other key immunizations for lung health are: 

• Pneumococcal shot to prevent bacterial pneumonia
• Tdap vaccine to protect against whooping cough

The pneumonia vaccine is typically given as a one‑time dose or short series, depending on your age and health status, and provides long‑lasting protection. The single-dose Tdap vaccine requires a booster shot every 10 years.
