THIRUVANANTHAPURAM: Administration of the second dose of Covid vaccine, that will increase the immunity by 81 per cent, in the state has almost stopped at a time when studies show that a single dose would not give the required protection against the mutant variants. The number of people who are due for a second dose after the stipulated time between doses have increased, and they are worried of becoming vulnerable to the infection.
At present, less than half of the target group above 45 years has received the first dose while only less than one fourth of them received the second dose. The 22 per cent coverage has not changed in the last three weeks.
