Blood Donors Kerala honors ten-year-old girl for her intention to donate blood.

WhatsApp Image 2020 08 11 at 10.04.54 - FIBDO

Fatima Sherin, a 10 – year – old girl who saw the news of the plane crash and the emergency blood needs of the victims, picked up her sister’s status from her mother’s phone and called the number seen on the status to see if she could donate my ten – year – old blood.
That naive question was taken up by all blood donation organizations on social media.
Proudly as a blood donation organization, Blood Donors Kerala visited her home and gave her a love gift
