District collectors across Rajasthan will line up to take their coronavirus vaccination shots today, with the state hoping to inoculate lakhs of frontline workers, including policemen and women, in the battle against the contagious virus. The state government is hopeful that the sight of senior officials taking the vaccine will send the right message to those lower down the chain and the general public - the the Covid vaccines are safe and effective, and should be received by whomever is identified on the priority list.
