Will a flu vaccination protect me from COVID-19?

Influenza and COVID-19 are two separate and different viruses. Different vaccinations are needed to protect you and those around you from each virus. 

Although we saw a reduction in flu infection rates in 2020, likely due to the higher than usual vaccination rate, along with the impacts of social distancing and increased hygiene, the influenza virus remains, and you can still be exposed to the virus in the community. It’s important to note that Influenza is still a serious illness that contributes to absence from employment, lost productivity, hospitalisations and, worst case, death.
