Health experts push dengue vaccine rollout

Published

Sri Lanka’s escalating dengue outbreak, with nearly 60,000 reported cases and 32 deaths so far this year, has intensified calls for the introduction of a dengue vaccination programme, as hospitals struggle with more than 1,000 daily admissions and outbreak control teams are deployed to eliminate mosquito breeding sites, Health Ministry sources said.

Ministry sources said that the current surge, driven by heavy monsoon rains and flooding linked to Cyclone Ditwah, has pushed case numbers close to levels seen in 2017, with infections nearly doubling between April and mid-June.

While vector control measures remain the country’s primary response, health experts point to a missing component in the national strategy: vaccination.

Globally, a tetravalent dengue vaccine designed to protect against all four serotypes has already been introduced in 41 countries, with 18.6 million doses administered across endemic regions including Indonesia, Thailand, Malaysia, Brazil and Colombia.

The vaccine was evaluated in the large-scale Phase 3 TIDES clinical trial involving more than 20,000 children and adolescents aged 4 to 16 across eight dengue-endemic countries, including Sri Lanka, with study sites in Colombo and Gampaha districts. Interim and final analyses published in peer-reviewed journals, including The Lancet Global Health, have reported sustained efficacy over several years of follow-up.

Since receiving its first approval in Indonesia in 2022, the vaccine has been prequalified by the World Health Organization (WHO) and is recommended for use in high-transmission settings for children aged 6 to 16 years.

Health experts argue that Sri Lanka already possesses the infrastructure needed for phased rollout, particularly through its school-based health system, suggesting that priority districts such as Colombo, Gampaha, Kalutara and Kandy could be targeted first.

They note that reducing severe dengue cases would ease pressure on hospitals during peak monsoon seasons, improve workforce productivity, and reduce disruption to education in high-incidence areas.

Concerns previously raised over vaccine safety in dengue-naïve populations are said to have been addressed in later-stage clinical data, which demonstrate protection across both previously exposed and unexposed individuals, reducing the need for pre-screening in large-scale public programmes.

Sri Lanka’s tourism sector, currently experiencing a strong rebound, could also benefit from the availability of a vaccine, with industry stakeholders noting that dengue risk perception continues to influence traveller confidence.

While the WHO maintains that vaccination should complement—not replace—mosquito control efforts, public health observers say Sri Lanka’s goal of eliminating dengue mortality by 2030 may require additional preventive tools beyond current strategies.

With the science established and implementation models already in place globally, the decision now rests on whether Sri Lanka will integrate vaccination into its national dengue response framework.

Norochcholai digs into dwindling coal stocks, two units slash generation

Plant’s output cut from 270 MW to 140 MW amidst dwindling stocks; energy analysts warn system remains “at a razor’s edge”

By Ifham Nizam

The Norochcholai coal-fired power plant is now digging into the last dredges of its coal stock, with two operational units forced to slash generation from around 270 MW to just 140 MW on Sunday as the plant ran critically short of fuel, according to independent energy analysts and sources familiar with the National System Operator (NSO).

The sudden reduction of approximately 130 MW in coal generation has once again exposed the fragile state of the country’s power supply arrangements, with the plant understood to have coal stocks sufficient only until Friday night.

“This is not how a coal plant is expected to operate. They are digging up the last dredges of coal from the plant,” an independent energy analyst told The Island.

The analyst questioned why the units had been allowed to reach this stage without earlier intervention, arguing that at least one unit should have been deloaded around 10 days ago to conserve the remaining coal.

Had that been done, the analyst said, the country could also have reduced its dependence on more expensive diesel-fired generation during the period when

coal stocks were being conserved.

The latest NSO generation figures highlight the continuing pressure on the system.

Around 7 p.m. on Sunday, when the night peak was reached, total demand stood at 2,552.7 MW. Coal contributed only 282 MW, while major hydro accounted for 1,215.8 MW and thermal-oil generation for 791.9 MW.

The night peak of 2,552.7 MW was substantially higher than the daytime peak of 2,246 MW, according to the NSO Generation Summary for August 30.

The most immediate concern is the remaining coal stock at Norochcholai.

Sources said the plant has coal only to Friday night, making the timing of the next shipment critical.

The first shipment under the emergency arrangement is expected to arrive on Friday, September 4, but the coal unloading will have to begin on the same day if

the power plant is to continue operating without further significant deloading.

That creates another potential vulnerability, with rough sea conditions posing an additional challenge to unloading operations.

Energy sector sources said that even the arrival of the September 4 shipment would not completely eliminate the danger.

The next shipment under the new coal tender would need to commence unloading around September 15. Any significant delay beyond that could again force the Norochcholai units to operate at reduced output.

“We are still at a razor’s edge”

The independent energy analyst said the situation should not be viewed merely as a question of whether a particular vessel arrives on time.

The situation also means that any further reduction in coal generation could have a direct impact on the use of oil-fired power generation, potentially increasing the cost of electricity generation.

The latest NSO figures already show the important role being played by thermal-oil generation during the evening peak, when demand rises sharply.

The analyst questioned the rationale behind allowing the coal units to continue operating at higher loading until stocks reached critically low levels instead of taking measures earlier to stretch the available inventory.
