Singapore is encouraging vulnerable groups to get vaccinated against the flu as influenza cases increase. Health officials are particularly urging those aged 65 and above, as well as children under five, to receive a flu jab. Individuals with chronic medical conditions are also strongly advised to get vaccinated to protect themselves from severe illness. This proactive measure aims to prevent a widespread outbreak and reduce strain on the healthcare system. Authorities emphasize the importance of vaccination as the most effective way to protect against influenza and its potential complications. The recommendation comes as seasonal influenza activity is currently elevated in the region. Getting vaccinated also helps protect those around you who may be more susceptible to the virus.
