A blood donation camp was organized in Manipal University Jaipur on 15-11-2019 from 08:00 AM to 6:00 PM under the banner of Rotract-Green Club with a vision of providing red support to the needy people and social welfare. The total units of 1703 were collected from student, teaching and non-teaching staff of Manipal University Jaipur. Prof.(Dr.) Sandeep Joshi event coordinator organized the event with the support from students volunteers and faculty members. The venue of the event was the Old food court. A team of doctors and nurses from the 15 different hospitals had come. President Prof. (Dr.) G.K Prabhu inaugurated the Camp. Blood donation by President Prof. (Dr.) G.K. Prabhu was an encouraging moment for all. In this camp, the overwhelming number of volunteers of Manipal University Jaipur has participated with Vivacity. Camp was duly appreciated by hospitals that were present there.

Our college team has prepared a verified and reliable Pan-India Compilation by clubbing all the good and verified pan India covid resources which were scattered online. This has helped several people till now when the second wave of COVID-19 pandemic is ravaging across the nation, taking toll over several lives. Serving all your emergency requirements. Has recieved an overwhelming outreach till now !! What we are doing : Our MUJ relief team has worked in three prime areas during such a crisis : 1) covid resource compilation, 2) one-to-one support team catering individuals , 3) making our own useful website/apps so that people may benefit from them. ▪️Collaborated with Indian Student Associations at Carnegie Mellon University(CMU), Oxford, UC Berkeley, and Jadavpur University Kolkata for a joint COVID India Endeavor ▪ Started our own university fundraiser for providing relief in the form of food and essential groceries to low wage-earners and people below the poverty line in India ▪️ Started University wide immunization drive link to our resource : https://linktr.ee/covidreliefmuj link to CMU's All India COVID resources website : https://bhiksha.github.io/IndiaCovidResources/ Link to slack channel for the joint India endeavor volunteership : https://join.slack.com/t/indiacovidresources/shared_invite/zt-pjqrtp82-mAxEas_Kcc77_L82KwQxcw
