1Current free pneumonia vaccines for seniors over 65 only last about 5 years.
2Experts urge adopting new, longer-lasting vaccines for better protection.
3Vulnerable seniors must get the new vaccine to prevent fatal infections.
📖 Easy Explanation
🔍 Background
Currently, seniors aged 65 and older can get free pneumococcal vaccines at public health centers or clinics. However, this vaccine's protective effect is short, lasting only about 5 years, raising concerns about the recurring risk of pneumonia over time.
📌 Key Points
Experts emphasize that the national support program must switch to newer, longer-lasting, and more powerful vaccines (like PCV20) to properly protect seniors' health. Although herd immunity has improved due to high child vaccination rates, seniors with weakened immune systems remain highly vulnerable to fatal pneumonia.
💡 Why It Matters
If the national immunization program adopts the new vaccine, seniors will be able to safely prevent pneumonia for a much longer period with just one shot. Even before the policy changes, those with weak respiratory systems should consult their doctors about getting the new vaccine.
