Rosemary Jane Boyton is a British immunologist who is Head of Lung Immunology and Adult Infectious Disease at Imperial College London.

[2] Boyton established the Imperial College London Lung Immunology Group, where she studies respiratory infection and asthma.

Boyton explained that to begin to reopen countries, there should be investment in increased testing, immune status return-to-work permits and contact tracing.

Boyton emphasised that there would be a need for more accurate and specific antibody tests, which could identify asymptomatic SARS-CoV-2 sufferers who have recovered from the disease, and seroprevalence data.

In the case of Severe Acute Respiratory Syndrome, 90% of survivors had virus-neutralising antibodies, and around half had strong T-lymphocyte responses.
