In a letter to PM Modi, Odisha chief minister Naveen Patnaik suggested four measures to improve the process of vaccination. Patnaik brought the issue of 'intermittent supply' of Covid-19 vaccine to PM Modi’s notice and said that the Centre needed to align their forces and work together to face the pandemic. He suggested vaccines are made available in the open market so that citizens who can afford them can buy the shots on their own. He also said vaccines, which have been approved by international credible agencies, should be cleared by the Indian government for use. Vaccine production units should be ramped up with the help of the Centre and state governments, he added. He also mentioned in his letter that metropolitan cities that contribute the most to the Covid tally should be prioritised in the vaccination drive.
