疫苗需求暴跌!GSK同Pfizer面臨挑戰




**GSK及輝瑞在美國的RSV疫苗銷售下降,因接種人數減少**

(路透社)— 由於監管機構縮小了目標年齡組,並表示目前這是一生一次的接種,美國GSK和輝瑞的RSV疫苗銷售大幅下降,排除去年接種過的數百萬人。

一些獨立藥劑師表示,秋季呼吸道合胞病毒(RSV)疫苗的需求比去年下降了三分之二。根據醫療數據公司IQVIA的報告和多位華爾街分析師的評論,銷量大致吻合。

這些疫苗對於輝瑞和GSK來說都很重要,因為他們希望在暢銷藥物面臨仿製藥競爭前建立新的業務。

輝瑞還在面對激進投資者Starboard Value的壓力,以及其COVID產品需求減弱,導致股價從疫情高峰下降約一半。這也迫使這家紐約的製藥公司宣布兩項總額超過55億美元的成本削減計劃。

首席執行官Albert Bourla對2023年RSV疫苗Abrysvo的推出感到失望,但公司對今年在美國的疫苗表現表示樂觀。

猶他大學的Erin Fox教授表示,RSV需求減慢是由於政府在六月決定縮小合資格接種者的範圍,相比去年推出時的情況。

“我認為我們會看到需要疫苗的患者數量減少。過去的需求已經滿足,現在接種的患者數量肯定會減少,”Fox說。

Jefferies分析師Peter Welford上週在一份報告中指出,目前的活動顯示GSK的Arexvy銷售可能在第三季度未達到華爾街的預期。

RSV季節通常在十月開始。

GSK發言人表示,900萬美國人,即市場的三分之二,已經接種了Arexvy,公司看到美國和全球市場的強勁增長機會。根據美國的估計,去年有24%的60歲以上成年人接種了疫苗,其中包括超過30%的70歲或以上成年人。

“我們繼續預期Arexvy能夠在高峰年創造30億英鎊(39.2億美元)的銷售額,”GSK發言人說。

輝瑞拒絕對此事發表評論。

**GSK保持領先地位**

去年,平均每週約有44萬人接種GSK或輝瑞的RSV疫苗,其中約65%接種了GSK的Arexvy,根據IQVIA數據。今年九月,這一平均數字約為每週15.7萬人。

美國大型藥房包括CVS Health和Walgreens拒絕就其銷量發表評論。

位於內布拉斯加州和愛荷華州的Kohll’s Pharmacy的David Kohll表示,他的疫苗預約在八月和九月比去年下降了65%。

紐約Plattsburgh的Condo Pharmacy的藥劑師兼老闆Steve Moore表示,他的銷量下降得更厲害。

“那些支持疫苗並對疫苗感到興奮的人可能已經接種了,”Moore說。

他的藥房去年大部分RSV疫苗是在多個人一起接種的活動中施打的。“我有第一個活動即將舉行,”Moore說。“以前可能有80人,現在只有6人。”

美國疾病控制與預防中心表示,疫苗應用於75歲及以上的成年人,以及60至74歲中因醫療狀況而面臨RSV重症風險增加的人群。去年,合資格年齡實際上是60歲及以上。

英國和加拿大也開始向其公民提供疫苗,英國針對75至79歲的人群接種輝瑞的疫苗。

CDC將疫苗分類為一次性接種,儘管公司計劃提交更多數據顯示再次接種的好處。

GSK在週二展示的數據顯示,Arexvy在第三個RSV季節中仍能有效預防重症,效力約為43%。

去年,GSK贏得了市場的三分之二,主要是因為其與零售藥房的合約。到目前為止,今年GSK保持了其主導地位,輝瑞在最近幾週獲得了一些市場份額。

2023年,GSK的Arexvy貢獻了12億英鎊(15.7億美元)的銷售額,而輝瑞的Abrysvo達到8.9億美元。預計GSK的銷售額今年會略有下降至約11.5億英鎊,而輝瑞的銷售額預計增長近40%至12億美元。

Moderna的mResvia在五月獲批,但由於獲批時間較晚,無法在最大藥房中分得市場份額,公司表示其市場表現可能會落後於其他兩者。

“這不是流感疫苗,”BMO分析師Evan Seigerman說。“這些你不會重複接種的疫苗,它們不是一種年金。”

**編者評論:**

GSK和輝瑞在美國的RSV疫苗銷售下降,反映了疫苗市場的複雜性,尤其是在公共健康政策和市場需求之間的微妙平衡。由於監管機構的政策改變,目標人群的縮小直接影響了需求,這也顯示出政策對市場的巨大影響力。同時,這也提醒我們,疫苗的推廣需要持續的教育和公共信任的建立,以確保長期的成功。

在這個背景下,GSK和輝瑞需要考慮如何在未來的疫苗推廣中更好地管理市場預期和需求,可能需要更多的數據支持以推動再接種的必要性。此外,隨著Moderna進入市場,競爭將進一步加劇,這對於疫苗市場的創新和價格競爭將產生深遠影響。

Use the original face exactly as it is, without changing a details. A striking, high-fashion editorial portrait of a white -skinned model, captured outdoors with a bright, sunny, slightly hazy ambiance reminiscent of the late 1980s or early 1990s.
Model and Styling
• Model: A female model with elegant features and dark, curly hair, posed looking over her shoulder towards the camera. Her expression is confident and alluring.
• Outfit: She is wearing a two-piece outfit (or a playsuit/romper) entirely covered in black and white polka dots.
• Top: A loose, long-sleeved shirt, worn off one shoulder, showcasing the neckline. The polka dots on the shirt appear slightly smaller and more uniform.
• Bottom: Matching shorts or a skirt with a tight, fitted silhouette, emphasizing her figure. The polka dots here appear slightly denser.
• Hat: A defining accessory—a dramatically oversized sun hat with a wide, floppy brim. The crown is white, and the large, voluminous brim is patterned with large black and white polka dots, cascading down. A black fabric tie/ribbon is visible around the crown.
• Accessories: Large, circular or crescent-shaped gold earrings dangle from her ears.
Lighting and Setting
• Lighting: Natural, bright, direct sunlight creating a warm, sun-kissed, and slightly nostalgic aesthetic. The overall color palette leans towards desaturated pastels and warm creamy whites.
• Setting: She is positioned on a rooftop, terrace, or balcony, with a hazy, mountainous or coastal landscape visible in the blurred background. The background is predominantly soft blues and pale purples, suggesting a distant view over a city or ocean.
• Composition: A vertical, full-body to three-quarter shot. The model is the central focus, framed against the soft background.
Keywords/Style
• Style: High Fashion, Editorial, Retro, 90s Fashion, Resort Wear, Glamorous, Iconic.
• Vibe: Sophisticated, Sunny, Vacation Chic, Bold Pattern. Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a cinematic studio portrait of a woman seated on a simple wooden chair with a minimalist design, positioned slightly to the left of the frame. She is captured in a contemplative pose, with her body turned to the left, her left arm resting gracefully on the back of the chair, and her right hand gently touching her face near her lips, conveying a sense of introspection and elegance. Her long, wavy hair cascades naturally over her shoulders, framing her face and adding softness to the composition. She wears an oversized, textured knit sweater that slips off her shoulders, exposing her collarbones and upper chest, emphasizing a relaxed and intimate mood. Her legs are bare, with her right foot flat on the ground and her left knee slightly raised, creating a dynamic line that guides the viewer’s eye through the composition. *** The background is a seamless, deep charcoal or dark brown studio backdrop, providing a rich, neutral setting that enhances the dramatic lighting. The lighting setup features a single, soft yet directional light source positioned to the left of the subject, casting gentle, sculptural shadows that highlight the contours of her face, shoulders, and arms, while creating a subtle gradient across her form. The light accentuates the texture of her sweater and the natural shine of her hair, adding depth and dimension to the image. The color palette is monochromatic with warm, muted tones—shades of gray, brown, and beige—contributing to a timeless, artistic aesthetic. The image is shot with a professional full-frame camera using an 85mm or 50mm lens at a wide aperture (f/1.8 to f/2.😎 to achieve a shallow depth of field, ensuring the subject is in sharp focus while the background remains softly blurred. The resolution is ultra-high, capturing every detail from the fine texture of her sweater to the subtle expression of her pose. The overall style is elegant, contemplative, and refined, emphasizing mood and atmosphere over overt glamour. Post-processing is minimal, maintaining natural skin tones, enhancing contrast and clarity, and preserving the authenticity of the scene. This portrait embodies a delicate balance between simplicity and emotional depth, making it suitable for fine art, editorial, or fashion photography. Drone photo near Christ the Redeemer in Rio.
