Chris Whitty and Patrick Vallance speaking at press conference

The video discusses the role of antibodies in providing protection against the virus, noting that while some antibodies are neutralizing, they fade over time, leaving the majority of the population susceptible. It highlights that only a small percentage of the population has been infected and developed antibodies, with higher rates in urban areas like London. The video also presents maps showing transmission rates across England, indicating areas of increasing or stable transmission.

What is the role of neutralizing antibodies in viral protection?

• They have no effect on viral protection.

• They increase the risk of reinfection.

• They offer temporary protection that can fade over time.

• They provide absolute and permanent protection.

What percentage of the population is estimated to have been infected and developed antibodies?

• About 50%

• Less than 8%

• Exactly 25%

• More than 80%

Why is the majority of the population still susceptible to the disease?

• Because only a small percentage have antibodies.

• Because the virus has been eradicated.

• Because antibodies provide lifelong immunity.

• Because everyone has been vaccinated.

In which area is the antibody prevalence slightly higher, potentially slowing the spread?

• Northern Ireland

• London

• Scotland

• Rural areas

What do the colors orange, yellow, and brown represent on the transmission rate maps?

• Regions with complete immunity

• Areas with no transmission

• An increasing rate of transmission

• A stable or falling transmission rate
