- On Sunday, the U.K. government rolled out a new nationwide antibody surveillance program, in which anyone over 18 years can opt-in when having a PCR test from Tuesday.
- Of those who test positive, up to 8,000 will be sent two home antibody tests. The U.K. Health Security Agency will offer finger-prick tests to help improve the understanding of immunity against COVID-19 from vaccination and infection.
- The first test will determine the level of antibodies a person had before their current infection. The second test should be taken 28 days after testing positive for COVID-19 and will measure antibodies generated in response to the infection.
