摘要:咱们身边 65 岁以上的长辈越来越多了 ——2025 年数据显示，欧盟 65 岁以上人口已占 21.3%，80 岁以上的人未来 75 年还会增加 2.5 倍。但老年人的免疫系统会随年龄变弱（也就是 “免疫衰老”），普通疫苗效果打折扣，一旦感染流感、肺炎这些病，不仅容易住院，还可能留下走路没劲、记忆力下降的 “长期后遗症”，甚至增加心脏病、中风的风险。好消息是，2025 年最新研究里，老年人疫苗有了不少新突破：流感有高剂量疫苗，肺炎有 21 价新疫苗，带状疱疹疫苗保护率能到 97%，连之前没疫苗的 RSV（呼吸道合胞病毒）也有了新选择。今天就跟大家掰扯清楚，这些疫苗怎么选、怎么打，才能真的护好爸妈。 一、先搞懂：为啥老年人打疫苗，比年轻人更重要？ 很多人觉得 “爸妈身体好，不用打疫苗”，其实正好相反 —— 老年人感染一次，后果可能比年轻人严重 10 倍。 首先是 “免疫衰老” 在拖后腿：随着年龄增长，老年人的 B 细胞、T 细胞（都是免疫系统的 “战士”）活性会下降，就算打了疫苗，产生的抗体也少、消失得还快。比如普通流感疫苗，在年轻人里能防 70% 的感染，但老年人可能只能防 30%-50%。 更麻烦的是，老年人常伴有高血压、糖尿病、慢阻肺这些 “共病”，一旦感染，很容易引发并发症。比如有慢阻肺的老人，得社区获得性肺炎的风险，是普通人的 20 倍以上；加拿大一项研究还发现，65 岁以上老人住过流感院后，12% 会去世，20% 会变得走路需要人扶（11% 甚至彻底失去自理能力）。 更隐蔽的是 “长期后遗症”：感染不只是 “发烧几天就好” 这么简单。比如得了带状疱疹，3 个月后还疼的 “带状疱疹后神经痛（PHN）”，会让老人连穿衣服都疼；就算是普通肺炎，康复后几年内，心脏病、中风的风险也会升高 —— 有研究发现，流感确诊后第一周，心肌梗死的风险会增加 6 倍！ 所以对老年人来说，疫苗不只是 “防发烧”，更是在防残疾、防重病，甚至防死亡。二、这 5 种疫苗，老年人现在有 “升级版” 可选！ 以前老年人常打的只有流感、肺炎疫苗，现在不一样了，5 种高风险感染都有了更适合的疫苗，咱们一个个说：1. 流感疫苗：别再只打普通款，高剂量/佐剂款更管用 流感每年都会变花样（“抗原漂移”），所以得年年打，但普通疫苗对老年人效果一般。现在有两种更好的选择： 高剂量流感疫苗（HD-TIV）：抗原量是普通疫苗的 4 倍（每株 60μg vs 15μg），能让老年人产生更多抗体。研究显示，它比普通疫苗减少 24% 的肺炎住院、17.8% 的流感住院，法国 2021-22 年的数据还显示，它防流感住院的效果比普通疫苗好 23.3%。 佐剂流感疫苗（aTIV）：加了 “佐剂”（比如 MF59）的疫苗，能唤醒更多免疫细胞。这种疫苗不仅抗体多，还能识别 “变异的流感病毒”（比如 H3N2 漂移株），防实验室确诊流感的效果比普通疫苗好 63%（调整后比值比 0.37）。 另外，mRNA 流感疫苗也在试：就像新冠 mRNA 疫苗一样，它生产快，能更精准地匹配当年的流行株。比如候选疫苗 mRNA-1010，对甲型流感的抗体反应比普通疫苗强，还有厂家在研发 “流感 + 新冠” 二联疫苗，以后打一针能防两种病，省得爸妈跑两趟。2. 肺炎疫苗：最新 21 价疫苗，覆盖更全 肺炎球菌是老年人肺炎、脑膜炎的 “头号凶手”，美国每年有 3 万老年人得侵袭性肺炎球菌病（IPD），2.5 万人会去世。以前常用的是 23 价多糖疫苗（PPV-23），但现在有了 “结合疫苗” 的升级版： 从 PCV-13（13 价）到 PCV-15（15 价）、PCV-20（20 价），再到 2024 年美国获批、2025 年欧洲获批的PCV-21（21 价疫苗），覆盖的 “肺炎球菌血清型” 越来越多。 特别是 PCV-21，比 PPV-23 多了 8 种老年人易感的血清型（看下面的表），能防更多类型的肺炎。虽然还没有直接的 “防住院” 数据，但它产生的抗体，比老疫苗更强、更持久（尤其是对免疫弱的老人）。 表 1：肺炎球菌多糖疫苗（PPV）与结合疫苗（PCV）的血清型组成  3. 带状疱疹疫苗：选 “重组款”，保护率高、维持久 带状疱疹是 “水痘病毒复活” 引起的，50 岁后发病率会飙升，80 岁以上老人几乎一半都会得。以前的 “减毒活疫苗（Zostavax）” 效果一般，70 岁以上老人用，保护率不到 20%，现在推荐的是 “重组带状疱疹疫苗（Shingrix）”： 它加了 AS01B 佐剂，能激发更强的 T 细胞反应，50 岁以上老人用，保护率能到 97%，70 岁以上也能到 89.8%—— 几乎不会得带状疱疹。 更省心的是，它保护时间长，打两针后能维持 10 年以上，就算是身体弱的 “frail 老人”，效果也不会打折扣；免疫低下的老人（比如肾移植后、得白血病的）也能打，这是老疫苗做不到的。4. 新冠疫苗：别停在 “基础针”，booster（加强针）要跟上 虽然新冠死亡率下降了，但老年人还是高风险人群。现在的重点是 “及时打加强针”： 3 针疫苗后，防重症、防死亡的效果还能保持在 80% 以上，就算感染了，也不容易住 ICU。 现在有针对最新变异株的 “更新款疫苗”，而且厂家在研发 “新冠 + 流感 + RSV” 三联疫苗，以后可能打一针就能防三种呼吸道病毒，对记性不好的老人很友好。5. RSV 疫苗：终于有了！保护能维持 2 年 RSV（呼吸道合胞病毒）以前被忽视了，其实它是老年人冬季肺炎的 “隐形凶手”—— 工业化国家里，50 岁以上老人每年约 150 万感染 RSV，21.4 万人住院，1.6% 会去世。2023-2024 年，三种 RSV 疫苗终于获批： 有含佐剂的（如 GSK 的 Arexvy，加了 AS01E），也有不含佐剂的（如 Pfizer 的 Abrysvo），还有 mRNA 疫苗（Moderna 的 mRNA-1345）。 效果都不错：防下呼吸道感染（比如肺炎）的效果在 66.7%-83.7% 之间，而且能保护 2 年 —— 不用像流感那样年年打。美国的真实世界数据也显示，打了 RSV 疫苗的老人，住院风险能降 80%。三、疫苗里加 “佐剂”，到底是在 “加什么料”？ 前面总提到 “佐剂疫苗”，很多人会问：“加佐剂会不会有副作用？” 其实佐剂是疫苗的 “好帮手”，专门帮老年人克服 “免疫衰老”。 简单说，佐剂就是 “唤醒免疫系统的闹钟”：它能在注射部位吸引更多免疫细胞（比如 dendritic 细胞，相当于 “情报员”），让这些细胞更高效地把疫苗里的 “抗原”（相当于 “敌人照片”）传给 T 细胞、B 细胞，从而产生更多抗体、更强的免疫记忆。 现在常用的佐剂有两种： MF59：一种油包水乳化剂（含角鲨烯，和皮肤里的成分类似），常用在流感疫苗里。它能促进炎症因子释放，帮 dendritic 细胞成熟，让抗体维持更久。 AS01B：用在带状疱疹疫苗里，包含 MPL（脂多糖衍生物）和 QS-21（一种植物提取物），能激发更强的 T 细胞反应 —— 这对带状疱疹特别重要，因为防带状疱疹主要靠 T 细胞。 研究显示，加了佐剂的疫苗，不仅抗体多，还能让免疫反应更 “广谱”（比如防变异病毒），副作用和普通疫苗差不多，不用太担心。四、给家属的 3 个小提醒，别让疫苗 “白打” 别纠结 “要不要年年打”，按指南来：流感、新冠需要每年打（因为病毒会变异）；RSV、带状疱疹疫苗能管 2-10 年，不用年年打；肺炎疫苗打一次 PCV-21，一般不用补打（具体遵医嘱）。 记好 “疫苗记录”：把爸妈打疫苗的时间、类型记在手机里，下次去医院时带给医生看 —— 比如打了 PCV-21，就不用再打 PPV-23 了，避免重复接种。 别信 “身体弱不能打”：除了严重过敏，大部分老人就算有高血压、糖尿病，也能打疫苗。比如重组带状疱疹疫苗，肾移植、白血病患者都能打，反而这些人更需要保护。 最后想说，对老年人来说，疫苗是性价比最高的 “健康保险”—— 花几百块打一针，能避免几万块的住院费，还能让爸妈少遭罪。2025 年这些疫苗新进展，都是为了让老年人的疫苗 “不白打、打得值”。如果爸妈还没打今年的疫苗，赶紧查下当地社区医院的接种时间，别错过了～ 识别微信二维码，添加生物制品圈小编，符合条件者即可加入 生物制品微信群！ 请注明：姓名+研究方向！ 版 权 声 明 本公众号所有转载文章系出于传递更多信息之目的，且明确注明来源和作者，不希望被转载的媒体或个人可与我们联系(cbplib@163.com)，我们将立即进行删除处理。所有文章仅代表作者观不本站。
