25-year-old Moiz Khan who works in Saudi Arabia is disappointed seeing the "No Vaccination Today" board at the Chennai Corporation's centre at Adyar. For the second day, he could not get his second dose without which he can't return to work. The state has run out of vaccines for the third time in three weeks. Many like him had to return without a shot. On Wednesday, Tamil Nadu administered only 28,270 doses against its recent daily high of 5.7 lakh doses.
