How Long Should You Wait Between Pneumonia Shots?
Knowing how long you should wait between pneumonia shots is critical for optimal protection against pneumococcal disease. Generally, adults over 65 should receive two different types of pneumonia vaccines, but understanding the recommended interval ensures maximum efficacy.
Understanding Pneumonia and its Vaccines
Pneumonia is an infection that inflames the air sacs in one or both lungs. These air sacs may fill with fluid or pus, causing cough, fever, chills, and difficulty breathing. Pneumonia can be caused by a variety of organisms, including bacteria, viruses, and fungi. Pneumococcal pneumonia, caused by the bacterium Streptococcus pneumoniae, is one of the most common and potentially serious types of bacterial pneumonia.
Two vaccines are available to help prevent pneumococcal disease:
- Pneumococcal conjugate vaccine (PCV15 or PCV20): Protects against 15 or 20 of the most common types of pneumococcal bacteria, respectively. PCV20 offers broader coverage in a single dose.
- Pneumococcal polysaccharide vaccine (PPSV23): Protects against 23 types of pneumococcal bacteria.
These vaccines work by stimulating the body’s immune system to produce antibodies that recognize and fight the pneumococcal bacteria.
Who Should Get Pneumonia Vaccines?
The Centers for Disease Control and Prevention (CDC) recommends pneumococcal vaccination for:
- All adults 65 years or older
- Adults 19-64 years old with certain medical conditions, such as:
- Chronic lung disease (e.g., COPD, emphysema)
- Heart disease
- Diabetes
- Chronic kidney disease
- Liver disease
- Weakened immune system (e.g., HIV, organ transplant recipients, those taking immunosuppressant medications)
- Cochlear implants
- Cerebrospinal fluid leaks
- Smoking
Vaccination is especially important for individuals at higher risk of complications from pneumococcal disease.
Recommended Vaccination Schedule and Intervals
The recommended schedule varies depending on prior vaccination history. How long you should wait between pneumonia shots depends on which vaccine you’re getting and whether you’ve had a pneumonia vaccine before.
For adults who have never received a pneumococcal vaccine:
- The current recommendation is to receive a single dose of PCV20.
- Alternatively, if PCV20 is not available, administer PCV15 followed by PPSV23. If this route is chosen, wait at least one year between PCV15 and PPSV23. However, for adults with certain immunocompromising conditions, cochlear implants, or cerebrospinal fluid leaks, the interval can be shortened to at least eight weeks.
For adults who have previously received PPSV23 but not PCV13, PCV15, or PCV20:
- Administer PCV20 at least one year after the PPSV23 dose.
- If PCV20 is not available, administer PCV15 at least one year after the PPSV23 dose.
For adults who have previously received PCV13:
- Administer PPSV23 at least one year after the PCV13 dose.
For adults who have previously received both PCV13 and PPSV23:
- No further pneumococcal vaccination is routinely recommended.
Why Timing Matters: Immunological Considerations
The timing between vaccinations impacts the immune response. Giving vaccines too close together may result in a reduced antibody response. Allowing appropriate time between doses allows the immune system to fully mature its response to the first vaccine before receiving another stimulation, leading to a more robust and longer-lasting protection. This concept, known as prime-boost vaccination, leverages different vaccine types to generate a broader and more effective immune response.
Factors Affecting Vaccination Decisions
Several factors may influence the decision of how long you should wait between pneumonia shots:
- Age: Adults 65 and older are at increased risk and should follow the recommended schedule.
- Underlying health conditions: Individuals with weakened immune systems or chronic illnesses may need to adjust their vaccination schedule in consultation with their healthcare provider.
- Prior vaccination history: Understanding which vaccines you have already received is crucial for determining the appropriate timing for subsequent doses.
- Vaccine availability: The availability of specific vaccine types (PCV20 vs. PCV15/PPSV23) may impact the chosen vaccination strategy.
Common Mistakes and Misconceptions
- Skipping vaccination altogether: The biggest mistake is not getting vaccinated against pneumococcal disease, particularly for those at higher risk.
- Assuming one vaccine is enough: While PCV20 provides broader coverage in a single dose, previous recommendations often involved sequential vaccination with PCV13/15 and PPSV23.
- Getting the vaccines too close together: Not adhering to the recommended intervals can diminish the immune response.
- Believing you are protected for life after one dose: While protection from pneumonia vaccines can last for years, staying up-to-date with recommended booster doses may be necessary, particularly for those at increased risk.
- Thinking the flu vaccine prevents pneumonia: While both can cause respiratory illness, they are distinct diseases. The flu vaccine protects against influenza viruses, while pneumococcal vaccines protect against pneumococcal bacteria.
Benefits and Risks of Pneumonia Vaccination
The benefits of pneumonia vaccination far outweigh the risks. Vaccination can significantly reduce the risk of:
- Pneumococcal pneumonia
- Bacteremia (bloodstream infection)
- Meningitis (infection of the membranes surrounding the brain and spinal cord)
- Hospitalization
- Death
Common side effects of pneumococcal vaccines are generally mild and may include:
- Pain, redness, or swelling at the injection site
- Fever
- Muscle aches
- Fatigue
Serious side effects are very rare.
When to Consult Your Healthcare Provider
Consult your healthcare provider if you have any concerns about pneumococcal vaccination. They can assess your individual risk factors, review your vaccination history, and provide personalized recommendations. It’s also essential to consult your doctor if you experience any unusual or severe symptoms after vaccination.

Frequently Asked Questions (FAQs)
Why are there different types of pneumonia vaccines?
Different vaccines target different strains of the pneumococcal bacteria. PCV15, PCV20, and PPSV23 offer varying levels of protection against different serotypes, and the recommendations for which vaccine(s) to receive are based on optimizing the breadth and durability of immune response. Newer conjugate vaccines like PCV20 offer broader coverage with fewer shots.
If I already had PPSV23, do I still need PCV15 or PCV20?
Yes, current recommendations suggest that adults who have previously received PPSV23 but not PCV15 or PCV20 should receive a dose of PCV15 or PCV20. The timing is important: wait at least one year after the PPSV23 dose. PCV15 or PCV20 provides better protection against some types of pneumococcal disease not covered by PPSV23.
Can I get pneumonia from the pneumonia vaccine?
No. The pneumonia vaccines cannot cause pneumonia. They contain either inactivated bacteria components (polysaccharides) or weakened, non-infectious versions of the bacteria (conjugate vaccines) that stimulate the immune system without causing illness.
What if I can’t remember which pneumonia vaccines I’ve had?
If you don’t know your vaccination history, it’s best to consult your healthcare provider. They may be able to access your records or recommend a course of action based on your age, health conditions, and risk factors. In some cases, revaccination may be recommended.
Are there any reasons why someone should NOT get a pneumonia vaccine?
People with a severe allergic reaction (e.g., anaphylaxis) to a previous dose of a pneumococcal vaccine or to any vaccine component should not receive the vaccine. Always inform your healthcare provider about any allergies or prior reactions to vaccines.
Is there an upper age limit for getting a pneumonia vaccine?
No. The recommendation for pneumonia vaccination applies to all adults aged 65 years and older, regardless of their current health status or age.
Does the time of year matter for getting a pneumonia shot?
The timing does not usually matter. While respiratory infections tend to be more common during the fall and winter months, you can get vaccinated against pneumococcal disease at any time of the year.
Can I get the pneumonia vaccine at the same time as the flu vaccine or COVID-19 vaccine?
Yes. The CDC states that pneumococcal vaccines can be administered at the same time as other vaccines, including the flu and COVID-19 vaccines. This can help streamline your vaccination schedule.
How effective are pneumonia vaccines?
Pneumonia vaccines are highly effective in preventing pneumococcal disease. PCV13, for example, has been shown to be about 45% effective in preventing pneumococcal pneumonia in adults 65 years and older.
Does smoking affect the effectiveness of the pneumonia vaccine?
Yes. Smoking weakens the immune system and can reduce the effectiveness of the pneumonia vaccine. Smokers are strongly encouraged to get vaccinated and to quit smoking to improve their overall health and immune function.
Where can I get a pneumonia vaccine?
Pneumonia vaccines are available at most:
- Doctor’s offices
- Pharmacies
- Health clinics
- Hospitals
Contact your healthcare provider or local pharmacy to schedule an appointment.
How Long Should You Wait Between Pneumonia Shots? – What if I have immunocompromising conditions?
If you have certain immunocompromising conditions like HIV, organ transplant, or are taking immunosuppressant medications, the interval between PCV15 and PPSV23 can be shortened to at least eight weeks instead of one year. This shorter interval is considered safe and can help provide quicker protection. Talk to your doctor for personalized advice. Knowing how long you should wait between pneumonia shots in your specific situation is critical.
