The Latest Advancements in Pneumococcal Vaccines
Pneumococcal disease, caused by the bacterium Streptococcus pneumoniae, can lead to serious conditions like pneumonia, meningitis, and bloodstream infections. The development of new pneumococcal conjugate vaccines (PCVs) has significantly expanded protection against these diseases, particularly for older adults and those with compromised immunity.
Introduction to PCV20 and PCV21
Until recently, older adults received a combination of PCV13 and PPSV23 to protect against pneumococcal disease. The landscape has changed with the introduction of new, higher-valent PCVs. Merck’s CAPVAXIVE™ (PCV21) and Pfizer’s Prevnar20™ (PCV20) are the latest innovations offering broader coverage.
Updated Recommendations and Eligibility
The Centers for Disease Control and Prevention (CDC) has expanded its recommendations for these new vaccines. In late 2024, the Advisory Committee on Immunization Practices (ACIP) updated its guidelines, recommending a single dose of PCV for all adults aged 50 and older who have not been previously vaccinated with a PCV or have an unknown vaccination history. Adults aged 19–49 with specific risk factors, such as chronic lung disease, also have updated guidance for these new vaccines.
The Arrival of New RSV Vaccines
Respiratory Syncytial Virus (RSV) is a common respiratory virus that can be especially dangerous for older adults and those with underlying health conditions. For years, there was no vaccine for RSV, but recent innovations have brought effective options to market.
What are the New RSV Vaccines?
Several RSV vaccines have been approved by the FDA and recommended by the CDC for older adults. These include:
- GSK’s Arexvy: Approved in 2023 for adults aged 60 and older.
- Pfizer’s Abrysvo: Approved in 2023 for adults aged 60 and older and for pregnant women to protect their infants.
- Moderna’s mResvia: Licensed in 2024, it is approved for adults 60 and older, and in 2025, it was also licensed for adults aged 18-59 at increased risk.
How RSV Vaccines Work and Who Should Get One
These vaccines use different technologies to stimulate an immune response. Arexvy and Abrysvo use a recombinant protein approach, while mResvia is an mRNA vaccine. A single dose is recommended based on shared clinical decision-making between a healthcare provider and the patient. The CDC recommends the RSV vaccine for all adults 75 and older, and for adults 50–74 with risk factors for severe RSV disease.
Comparison of the Latest Pneumococcal Vaccines
Choosing the right pneumococcal vaccine can be complex due to the different serotype coverages. Here is a comparison of the newest conjugate vaccines for adults:
| Feature | Prevnar20 (PCV20) | CAPVAXIVE™ (PCV21) |
|---|---|---|
| Serotypes Covered | 20 serotypes | 21 serotypes, including 11 unique to PCV21 |
| Target Population | Adults 18+ | Adults 18+ |
| Coverage Advantage | Includes Serotype 4, relevant in some populations and geographic areas. | Broader coverage against serotypes causing invasive pneumococcal disease in adults over 50. |
| Consideration | Simpler regimen with a single shot. | May provide better coverage for common adult serotypes, but consult your doctor about regional prevalence. |
Navigating Your Vaccination Schedule
For older adults, staying up-to-date on vaccines for lung health requires coordination. It's not just a matter of getting one shot, but the right combination and timing. Pneumococcal vaccines can be administered alongside other routine vaccines. However, your healthcare provider will determine the best schedule based on your medical history.
The best way to protect yourself is to speak with a healthcare professional. They can review your complete health history, including any prior vaccinations, to create an optimal immunization plan. This includes assessing your eligibility for the newest lung vaccines and other critical immunizations, such as the annual flu shot.
Potential Side Effects
Like all vaccines, the new pneumococcal and RSV vaccines can have side effects, which are generally mild and resolve within a couple of days. Common side effects for both types of vaccines may include pain, swelling, or redness at the injection site, fever, fatigue, headaches, and muscle aches. Serious side effects are rare, but it is important to report any adverse events to your healthcare provider.
The Bigger Picture: Importance of New Vaccines
The introduction of these new vaccines marks a significant step forward in preventative healthcare for older adults. By offering broader and more effective protection against two major causes of respiratory illness, these immunizations have the potential to reduce hospitalizations, severe illness, and death. With a growing elderly population, these tools are vital for maintaining public health and quality of life.

Conclusion: Taking Control of Your Respiratory Health
Staying informed about what is the new vaccine for lungs? is the first step towards better respiratory health in older age. With effective new vaccines now available for both pneumococcal disease and RSV, adults, especially those over 50, have more powerful tools than ever to protect themselves. By consulting with a healthcare provider and following updated guidelines, you can build a robust defense against serious respiratory infections and maintain your wellness.
