Metro Manila (CNN Philippines, September 1) — The health department of the city of Manila halted all its vaccination operations after encountering a technical problem in its online vaccination system, the Manila public information office announced on Wednesday.
All vaccination sites in Manila for both first and second doses of COVID-19 vaccines were closed at 4 p.m.
City health department chief Arnold Pangan said authorities are still looking into why the system went down, the Manila PIO added.
Early last month, the local government revealed that its vaccination registration website was attacked by hackers after receiving nearly a million “bot-triggered” registration requests. City officials had suspected that the perpetrator had a “troll farm generating machinery” to operate the attack.
