Controlled Trials Needed for Ebola Vaccines: Fauci

The video discusses the Ebola virus, highlighting the importance of early detection and repeated testing due to low viral loads in initial stages. It emphasizes public education to dispel fears, noting that Ebola spreads through direct contact with body fluids. The ethical necessity of controlled trials for vaccines and therapies is debated, stressing the need for evidence of safety and efficacy. The video also highlights global health security, advocating for improved infrastructure to prevent future epidemics. Finally, it addresses the fluctuating media attention on public health issues.

Why might an Ebola test initially show a negative result even if the person is infected?

• The person has developed immunity.

• The virus is not present in the body.

• The test is faulty.

• The virus is at a low level in the body.

What is the primary way Ebola is transmitted between individuals?

• By touching surfaces.

• Through the air.

• Through contaminated food.

• By direct contact with body fluids of an infected person.

What is a key reason for conducting controlled trials for Ebola vaccines?

• To distribute vaccines quickly.

• To ensure vaccines are safe and effective.

• To increase public awareness.

• To reduce costs.

What is a potential risk of using unproven Ebola therapies?

• They require special storage conditions.

• They may be ineffective and toxic.

• They are too expensive.

• They are difficult to administer.

What lesson does the Ebola epidemic teach about global health infrastructure?

• Health infrastructure is not important for epidemic control.

• Only developed countries need strong health systems.

• Weak health systems in any part of the world can pose a global threat.

• Epidemics are only a local concern.

What is the purpose of a global health security agenda?

• To reduce healthcare costs.

• To limit the spread of information.

• To focus on local health issues.

• To improve health infrastructure worldwide.

Why might media attention on public health threats fluctuate?

• Because of seasonal variations.

• As a result of new scientific discoveries.

• Because of ongoing threats and public fatigue.

• Due to changes in government policy.
