Opinions (5)

• This is an expert's assessment and prioritization, reflecting their professional judgment.
• This conveys the subjective assessment and emotional response of MSF to the situation.
• This expresses Feinberg's professional optimism and provides an estimated timeline, which involves a degree of professional judgment.
• This statement expresses Moderna's commitment and intent, reflecting their corporate stance and future plans.
• This is a statement about the expected outcome of the vaccine's mechanism, which is a projection based on scientific understanding.

Claims (5)

• While based on expert opinion, 'worst ever' is a superlative that is speculative and depends on future developments.
• This is a speculative comparison to a past event, framed with 'growing concern' and 'could reach,' indicating a potential future scenario rather than a confirmed fact.
• While these numbers are likely based on historical data, the phrasing 'nearly' and 'more than' introduces a slight imprecision that could be considered a minor dubious claim if exact figures are expected.
• While the intent is factual, the success and efficacy of this modified vaccine are not yet proven, making the statement about 'fighting Bundibugyo' a claim about future capability.
• This is a statement of potential future outcomes ('could affect') that are not yet confirmed and are subject to trial results.
