Should l Buy MRNA?

- Impact Assessment: The recent hantavirus outbreak on a cruise ship has sparked a rally in the biotech sector; however, due to its transmission primarily through contact and a much lower contagion rate compared to COVID-19, the market for hantavirus vaccines may be limited, affecting the long-term profitability of related companies.
- Predicting Winners: Even if the situation worsens, it remains challenging for investors to identify which companies will successfully develop hantavirus vaccines, as historical data shows that even major pharmaceutical firms like Sanofi and Merck failed to dominate the COVID-19 vaccine market, highlighting the complexities of investment risks.
- Return on Investment Risks: Even if investors choose companies that successfully develop vaccines, market-beating returns are not guaranteed; data indicates that companies like Pfizer and Moderna, which excelled during the COVID-19 peak, have underperformed the S&P 500 since then, reflecting market uncertainties.
- Potential Investment Opportunities: Despite challenges, Moderna and Pfizer are still considered attractive vaccine manufacturers; Moderna has been working on a hantavirus vaccine and has a promising pipeline, while Pfizer's replenished pipeline and upcoming pivotal trials make it a stock worth serious consideration for long-term returns.

Cruise Ship Hantavirus Outbreak Raises Concerns
- Outbreak Overview: As of Tuesday, the WHO reported 11 cases linked to the cruise ship hantavirus outbreak, with 9 confirmed cases including 3 deaths, although no positive cases have been found in the U.S., indicating a potential threat.
- Public Health Risk: While the risk of hantavirus transmission is low, primarily spread through contact with infected wild rodents, experts warn that the cruise ship environment may exacerbate the risk of virus transmission, especially in confined spaces.
- CDC Response Capability: Experts point out that the CDC's delayed response to the outbreak, coupled with a lack of effective leadership and resources, may hinder the U.S.'s ability to respond to future infectious disease threats, particularly after staffing cuts and strained relations with the WHO.
- Future Outbreak Preparedness: Public health experts emphasize that the current outbreak exposes vulnerabilities in the U.S. public health infrastructure, calling for a restoration of the CDC's expertise and resources to effectively respond to potentially more transmissible pathogens in the future.

Hantavirus Outbreak Raises Public Health Concerns
- Outbreak Overview: As of Tuesday, the WHO reported 11 cases linked to the hantavirus outbreak, with 9 confirmed cases including 3 deaths; while no positive cases have been found in the U.S., public concern is rising significantly.
- Monitoring Measures: In the U.S., 18 individuals are being monitored across Nebraska and Atlanta for potential exposure, and although more cases may emerge, experts assert that the risk remains low due to the hantavirus's limited transmissibility.
- CDC Response Capability: While the CDC appears to have the outbreak under control, experts warn that past cuts to the agency and the withdrawal from the WHO may undermine the U.S.'s ability to respond to future infectious disease threats, especially against more contagious pathogens.
- Vaccine Development Progress: Moderna's shares surged approximately 12% after confirming it is researching a potential vaccine for hantavirus, although specific treatments are still years away, this development may provide hope for future public health responses.

FDA Commissioner's Departure Triggers Biotech Market Reactions
- Leadership Change: The departure of FDA Commissioner Marty Makary is perceived as a positive signal for the biotech sector, although analysts warn that the industry may face pressure until a permanent replacement is found, potentially leading to market volatility.
- Market Reaction: The Nasdaq biotechnology index rose 1% on Tuesday, reflecting an initial positive response from investors to Makary's exit, particularly following his public disagreements with drugmakers like Replimune and Moderna.
- Increased Uncertainty: Analysts caution that the ongoing leadership vacuum at the FDA could result in more delays and unpredictability, diminishing the agency's ability to provide guidance and credible policy commitments, thereby impacting the investability of the biopharma ecosystem.
- Stock Performance: Shares of uniQure and Replimune rose by 5% and nearly 10%, respectively, indicating market optimism regarding new leadership, although Makary's departure also introduces uncertainty within the industry.

FDA Commissioner Makary Resigns Amid Controversy
- Makary Resignation: FDA Commissioner Marty Makary resigned on December 18, 2025, concluding a controversial tenure marked by criticism over the government's COVID-19 response and drug approval processes, which drew backlash from various stakeholders.
- Acting Commissioner Appointment: President Trump announced that Kyle Diamantas will temporarily take over as acting commissioner, having previously served as the top food official at the FDA, and will need to navigate the complex drug approval landscape left by Makary.
- Internal Turmoil Intensifies: Under Makary's leadership, staff morale at the FDA plummeted due to layoffs and departures, notably that of cancer regulator Richard Pazdur, leading to increased distrust in leadership and impacting the agency's stability.
- Drug Approval Controversies: During Makary's tenure, the FDA rejected several rare disease treatments, raising concerns within the pharmaceutical industry, particularly as negotiations for the reauthorization of the Prescription Drug User Fee Act highlighted the industry's sensitivity to leadership changes at the FDA.
