Chief Medical Officer Professor Chris Whitty delivering Downing Street press briefing

The video discusses the efficacy of vaccines, highlighting their strong protection against severe disease and mortality, but less so against mild disease and transmission. It emphasizes the importance of prioritizing vaccines for the most vulnerable, particularly by age, to maximize public health benefits. The video also considers geographical factors and the spread of new variants, advocating for targeted vaccination efforts in highly affected areas.

What is the primary benefit of vaccines according to the first section?

• Increasing asymptomatic cases

• Preventing mild diseases

• Reducing transmission

• Protecting against severe illness and death

How does vaccine efficacy change with new variants?

• It decreases for mild diseases first

• It remains the same

• It increases for mild diseases first

• It decreases for severe diseases first

Why is age a significant factor in vaccine prioritization?

• Older people have a higher risk of severe disease

• Younger people are more likely to transmit the virus

• Age does not affect vaccine prioritization

• Older people have a lower risk of severe disease

What is the main goal of the vaccine distribution strategy discussed in the third section?

• To prioritize those at higher risk

• To vaccinate everyone equally

• To ignore geographical spread

• To focus on urban areas only

How does the strategy address the spread of new variants?

• By vaccinating only young people

• By ignoring geographical differences

• By accelerating vaccination in affected areas

• By focusing only on rural areas
