But this year's "Passing the Merit with Blood Don-ation" campaign yesterday urged existing donors to give blood banks a shot in the arm by upping their donations to once every three months.
The Red Cross's blood donation chief Wan-lop Chiaravanont also invited those who give blood to family members to spread the benefit further.
Merit-making activity
He added that the campaign would focus on blood donation as a merit-making activity, encouraging people to do it on birthdays and religious holidays. This would increase the amount of donations and help to meet patients' needs.
Those donating blood for the second time from April will receive a "merit-recording" book with speeches by Their Majes-ties and HRH Princess Maha Chakri Sirindhorn.
