• Says that it would otherwise be a sheer waste of money 

CWC (Ceylon Workers’ Congress) Vice President Senthil Thondaman said Sri Lanka should do antibody testing of people and order only the most efficacious vaccine in the future to be administered as booster shots.   
Mr. Thondaman told Daily Mirror that it would otherwise be a sheer waste of money. He said the antibody level of people would be different after administration of second doses. 

 
He said the required number of booster shots could be identified after a proper antibody testing.
