IMB virologist Dr Larisa Labzin answers questions on long COVID and whether scientists could eventually develop a vaccine against all COVID-19 variants.
An international team has found a way to potentially prevent the novel coronavirus from infecting cells, as well as clues as to why it is more infectious than similar viruses.
Scientists think face masks help limit virus spread by protecting everyone else from the infected wearer. As a result, face masks are now mandatory in many cities, states and countries to limit the spread of COVID-19.
Some new studies have found people who were never symptomatic, exposed to, or tested positive for COVID-19 that have immune cells that can recognise COVID-19.
Instead of protecting us from the virus that causes COVID-19, the body's natural defence mechanisms can overreact and inflict damage. Understanding why could make the infection far less dangerous.
