21世纪经济报道记者季媛媛闫硕上海北京报道 HPV感染是全球重要的公共卫生问题之一，男性和女性都面临着感染风险。而接种疫苗是预防HPV感染 的最佳方法。 根据21世纪经济报道记者的梳理，目前我国市场上销售的HPV疫苗包括默沙东的四价HPV疫苗（佳达修 ®）和九价HPV疫苗（佳达修®9）、GSK的二价HPV疫苗（希瑞适®）、万泰生物的二价HPV疫苗（馨 可宁®），以及上海泽润的二价HPV疫苗（沃泽惠®）。但眼下，二价HPV疫苗的销售情况受到九价 HPV疫苗扩龄和市场竞争加剧的影响，导致销售量未达预期，进而影响了公司的营收。 财报数据显示，万泰生物2024年营业收入为22.45亿元，同比下降59.25%；归母净利润为1.06亿元，同 比下降91.49%。该数据低于大多数分析师的预期。 面对利润的急剧下滑，万泰生物此前直言：其疫苗业务因市场波动、政府集中采购政策以及九价HPV疫 苗适用年龄段的扩展等多重因素，导致销售未达预期，进而引发疫苗板块的收入与利润显著下降，最终 陷入了净亏损的境地。 2019年底，二价宫颈癌疫苗（馨可宁 Cecolin）获批并于2020年5月上市销售。此前，万泰生物借此在4 年内完成"三级跳 ...
