The flu strain ripping through the UK, known as H3N2, is relatively new, meaning many people may not have immunity. By November 18, flu cases were already surging, according to latest data from the UK Health Security Agency (UKHSA). In a normal flu season, the R rate – the average number of people an infected person passes the virus on to – is around 1.1 to 1.2. And it follows the biggest flu season in Australia’s history, which is often an indication of what is to come in England and the rest of the northern hemisphere. In the UK, flu vaccines are available for everyone aged 65 and over, under 65s who are at clinical risk, pregnant women, care home residents and carers.
