21世纪经济报道记者唐唯珂广州报道 与此同时，人口结构变化也在影响疫苗需求。因为新生儿数量持续下降，传统儿童疫苗（如麻疹、水痘 等）的市场需求也随之减少，而成人疫苗市场（如HPV、带状疱疹疫苗）尚未完全激活。尽管专家呼吁 慢性病患者（如心血管疾病、糖尿病患者）应积极接种流感、肺炎疫苗以降低并发症风险，但公众认知 度不足，"疫苗犹豫"现象普遍存在，导致市场推广难度加大。 一方面，存货积压和回款困难则进一步吞噬了疫苗企业的利润。2025年一季度，万泰生物计提减值 5132.59万元，其中应收账款坏账损失高达4582.81万元；智飞生物资产减值损失达3833.61万元，主要因 存货跌价准备增加，反映出市场销售不及预期导致的库存积压问题；沃森生物、康泰生物的资产减值和 信用减值损失较2024年同期分别增加5242.83万元、1730.44万元，显示行业整体资金链压力仍在上升。 2025年一季度，A股疫苗企业的业绩表现依然低迷。 21世纪经济报道记者梳理已公布一季报的14家疫苗企业后发现，其中8家归属于上市公司股东的净利润 同比下滑，占比超半数，且前5家企业净利润降幅超过80%。 龙头企业同样未能幸免。万泰生物（603 ...

2024年及2025年一季度，疫苗行业均呈现比较严重的下滑趋势。从财务数据看，行业总营收从2020年的 1060亿元增至2023年的1637亿元，年均复合增长率达11.5%，2021年同比增速更达34.5%。然而2024 年，行业总营收骤降至1283亿元，同比下滑21.6%，为近五年首次负增长，显示行业进入调整期。 从利润表现看，行业净利润在2021年达到309亿元峰值后持续下滑，2024年降至120亿元，较峰值缩水 61%，同时盈利质量出现恶化迹象，净利润率从2021年的21.7%降至2024年的9.4%，成本压力显著抬 升。主要原因在于疫苗渠道库存压力较大，导致企业发货受到不利影响以及2价HPV疫苗、PCV13、 Vero细胞狂苗等竞争格局趋于激烈。 个股方面，头部企业业绩分化现象显著。其中，天坛生物、西藏药业逆势突围，天坛生物2024年营收60 亿元，同比增长17.6%；净利润15亿元，同比增长36.4%，毛利率提升至54%。西藏药业2024年净利润10 亿元，同比增长25%，毛利率连续三年超94%。 而智飞生物、万泰生物受HPV疫苗市场竞争加剧及集采影响业绩均出现大幅下滑。智飞生物2023年营收 52 ...
