An International team of scientists has launched a global hunt for rare people who may be genetically resistant to SARS CoV-2 infection. Individuals who’ve been exposed to the virus living in families where everyone else in the household got infected, who repeatedly tested negative and didn’t mount an immune response. Claudia Hammond speaks to immunologist Evangelos Andreakos, part of the team at the Biomedical Research Foundation in Athens about this fascinating quest. And Claudia hears from Norway about more reassuring research into Covid vaccination in pregnancy.
