Share Aligarh: People who waited fervently for a quick and effective solution to the raging pandemic are seen nonplussed after the Covid-19 vaccine roll-out, said Prof Zeeba Zaka-ur-Rab, Department of Paediatrics, Jawaharlal Nehru Medical College (JNMC), Aligarh Muslim University (AMU). She was speaking as a panellist in a webinar on ‘Covid-19 vaccine roll out in Uttar Pradesh: Challenges and Opportunities’ remotely hosted through Harvard’s Zoom platform, by Harvard T H Chan School of Public Health – India Research Center and Project SANCHAR. “Like in Uttar Pradesh (UP), delay in acceptance or refusal of vaccine against Covid-19 despite its availability, is a key hindrance in achieving optimal vaccination coverage among populations around the globe,” added Prof Zeeba.
