Professor Neelika Malavige in the Department of Immunology and Molecular Medicine, Faculty of Medical Sciences, was quoted by local Daily Mirror newspaper as saying on Monday that all adults need to be vaccinated to prevent severe illness and death from the Delta variant, reports Xinhua news agency.
"We are in danger as the Delta variant causes havoc on severe disease and deaths until the population is vaccinated. The vulnerable population is adults," Malavige said.
Presently Sri Lanka is administering over 300,000 doses of Covid-19 vaccine every day for those above the age of 30 years with 7 per cent of its eligible population fully inoculated, and medical experts have not recommended opening the country till all within the age group are immunised.
Only vaccinations are complete, especially on adults, can the country think of returning to complete normalcy, medical experts have said.
Authorities have set a target to complete inoculations by the end of August or the beginning of September, Malavige said.
The leading vaccine currently being administered in Sri Lanka is the Sinopharm vaccine, according to statistics from the health ministry.
Over 5 million people have been inoculated nationwide while the vaccination program is ongoing in full scale, health authorities said.
To date, the country has reported 284,933 confirmed Covid-19 cases, with 3,779 deaths.
