When India had rolled out the crucial and world's largest vaccination drive on Saturday to combat the COVID-19 pandemic, the Maharashtra state government has decided to suspend the drive till Monday owing to the technical issues that were emerged from the Co-Win app. 

The chaos amid the aggressive vaccination had concerned the state and Central governments, pushing them to fix the technical glitch in the mobile application, which holds a major part to ascertain how the drive has got unfolded. The Co-Win app has been created by the Center for managing registration for the inoculation of the vaccine. 

India had launched the drive on Saturday with the target of vaccinating three crore frontline workers. Prime Minister Narendra Modi had launched the drive and the states and the union territories began vaccinating the workers with two indigenous vaccines- Covishield and Covaxin. The government had campaigned about the Co-Win app for registering for the COVID-19 vaccine. 

However, the application wasn't well-received in Maharashtra as the state had witnessed technical glitches which pushed the government to suspend the vaccination drive. According to PTI, Maharashtra Health Minister Rajesh Tope on Saturday said, "Not just in Maharashtra, everywhere in the country this app created problems in the execution of vaccination drive. We have decided to suspend the vaccination for the next two days". 

Tope further stated, "When a dry run was conducted in the state on January 8 and again today I specifically pointed out problems with the Co-Win app, and Union Health Minister Harsh Vardhan said he will look into it". On Saturday, a health official in the state health department said that text messages were not sent to many people who were supposed to get the vaccine shot on Saturday due to problems in the Co-Win app. 

The state government had planned to inoculate 28,500 health workers on the first day of the vaccination drive but due to the problems in the app, the government was only able to vaccinate only 65% of the first day's target. The official said that the healthcare workers couldn't come to the center for receiving shots as they hadn't received messages due to the issue in the application. 

While Hingoli district of Maharashtra recorded 100% vaccination as all 200 health workers who were supposed to be inoculated on the first day had received the shots, Mumbai city and Mumbai Suburban districts reported the lowest - 47% and 49% - inoculation of the target. According to the Union Health Ministry, 1,65,714 frontline workers across India had received vaccines on Saturday. 

Co-Win is an online platform developed by the health ministry for conducting the vaccination drive. The beneficiaries are requested to register themselves on the application for the vaccination. Information related to the time of appointment, the next dose of vaccine, and other issues will be disseminated through the application.
