People in South Korea aged 70 and older will be able to get free flu shots starting today.
They'll be available at public health clinics and designated medical centers.
Starting with this group, in phases, the free flu shots will cover more than 10-and-a-half million seniors.
The second round will be for seniors aged 62 and above.
That will start October 26th.
Vaccines are already available for pregnant women and children 12 and under.
The authorities want to prevent a major flu outbreak, which would make fighting COVID-19 even harder.
