Department of the Interior and Local Government Secretary Benjamin "Benhur" C. Abalos Jr. on Thursday urged local government units to immediately address the 1.4 million backlogs in the encoding of VaxCertPH.

VaxCertPH is government's official digital vaccination certificate program, in the Vaccination Information Management System.

"This has long been an issue in our LGUs as we try to improve the inventory of Filipino citizens who have registered for VaxcertPH. We implore our LGUs to work double time in addressing their backlogs in the VIMS," Abalos said in statement.

As of 22 September, the VIMS, VaxCertPH's official central database, has a backlog of a total of 1,460,582 vaccination records of citizens.

Of this number, he said, 334,317 were due to missing records; 308,386 were not recorded for lack of manpower; 243,300 due to late submission; 122,897 for incomplete data; 109,806 for missing data fields; 94,575 for operational and procedural issues; and, 75,831 due to issues with internet connections, among others.

According to the Department of Information Communications Technology, lack of internet connection; lack of manpower in encoding; missing data and records; incorrect data and records; and, lack of response from LGUs are major causes of the backlog.
