• End of September, end of November

• End of October, end of December

• End of November, end of February

• End of December, end of January

What is the estimated cost range for developing a vaccine according to large pharmaceutical companies?

• $2 billion to $3 billion

• $1 billion to $2 billion

• $500 million to $1 billion

• $100 million to $500 million

How long does it typically take to develop a vaccine?

• 3 to 4 years

• 1 to 2 years

• 5 to 10 years

• 11 to 15 years

What could potentially restart the COVID-19 epidemic in a country that has controlled it?

• A mutation in the virus

• A new strain of the virus

• A change in weather conditions

• A traveler from another country

What are some of the disruptions caused by COVID-19 mentioned in the transcript?

• Improved public health systems

• Increased tourism and travel

• Economic growth and expansion
