Immunologist raises fears of second lockdown

The country's heading for a "second surge" of Covid-19, unless the government outlines its clear plan to deal with the virus.

Dr Tomás Ryan from Trinity College's School of Biochemistry and Immunology says there's a risk we are heading for a second lockdown -
