However memory T-cell and B-cell responses persisted

A study conducted by Sri Jayewardenepura University researchers found that while the SARS-CoV-2 specific total antibodies of those inoculated with Sinopharm declined after 12 weeks from the second dose, the memory T cell and B cell responses persisted.

Given below is the press release issued by the University pertaining to the study: “The Sinopharm is an inactivated COVID-19 vaccine, which is currently given emergency use authorization by the WHO and is the main vaccine used in many Asian and Middle East Countries. A new study was carried out to determine the kinetics and persistence of immune responses following the Sinopharm/BBIBP-CorV, by investigating the immune responses in a cohort of Sri Lankan individuals.

“Antibody responses declined in all age groups, especially in those who are more than 60 years after 12 weeks from the second dose, while T cell responses persisted.” Said Prof. Neelika Malavige, Head, Department of Immunology and Molecular Medicine of University of Sri Jayewardenepura.

“USJ researchers including Prof. Neelika Malavige and Dr. Chandima Jeewandara from Allergy Immunology and Cell Biology Unit, Department of Immunology and Molecular Medicine of the University have been studying immune responses to different types of COVID-19 vaccines used in Sri Lanka.

“Results of the current research show that while the SARS-CoV-2 specific total antibodies, and especially neutralizing antibodies and antibodies to the receptor binding domain significantly declined, the memory T cell and B cell responses persisted.

“Since the ACE2 receptor blocking antibodies (neutralizing antibodies that associate with protection) was shown to significantly decline in all age groups and especially in the elderly, it is important to carry out long term efficacy studies to assess the waning of immunity on hospitalization and severe disease in order to decide on booster doses in different populations.” said Prof. Malavige.”

Govt. confident of 2/3 majority despite NPP split speculation

Published

Anura / Harini

By Shamindra Ferdinando

The ruling NPP yesterday (21) dismissed claims of a widening rift, within the government, over the proposed 22nd Amendment. Asked whether the NPP was concerned over a section of the Opposition alleging Prime Minister Dr. Harini Amarasuriya and two dozen MPs taking a view contrary to that of the party in this regard, authoritative party sources said some persons were propagating speculation for their own interest.

Declaring that there was absolutely no issue regarding the controversial Amendment, sources emphasised once it was tabled in Parliament, it would be passed with 2/3 majority.

Sources dismissed claims that out of its 159-member parliamentary group a section of NPPers was opposed to the government move. According to an influential Opposition activist, there are 57 JVPers and 66 NPPers in the government group and the rest contested the last parliamentary polls, having aligned with the JVP.

Ministerial sources told The Island that the government was confident of going ahead with the 22nd Amendment and Judicature (Amendment) Bills. Sources said that the NPP was not bothered about the Opposition protests in and outside Parliament.

Speaker Dr. Jagath Wickremaratne is expected to disclose the confidential ruling that he received from the Supreme Court in respect of more than 65 petitions for and against the 22nd Amendment and Judicial Amendment Bills. The enactment of the 22nd Amendment would pave the way for extending the retirement age of Supreme Court judges, from 65 to 67 years, and Court of Appeal judges, from 63 to 65 years.

Protest against setting up of cement factory in highly populated area near BIA

Published

The cement factory premises located in close proximity to a school and the lagoon

… school alleges deception

What began quietly as a single-storey tourist hotel, on the edge of Katunayake-Seeduwa has, five years later, morphed into a looming five-storey cement factory and with it, a storm of fear, anger and unanswered questions.

At a media briefing held on 19 September at St. Thomas International School, Seeduwa, the community finally found its voice. The gathering included priests, school principals, environmental defenders, and parents whose children study within a few hundred metres of the site.

The briefing was led by Rev. Fr. Jude Chrishantha Fernando, Director of National and Archdiocesan Catholic Social Communications, Rev. Fr. Nilantha Heshan, Director of the Archdiocesan Sethsarana Institute, Dinusha Nanayakkara, Convener of the Archdiocesan Committee for the Protection of Muthurajawela, and Attorney-at-Law Ms. Isuri Rodrigo.

Their message was clear: This is not a campaign against development.

“We Are Not Against Cement. We Are Against Deception.”

“Cement is an essential raw material for the country. We have no opposition to any such factory or production plant,” they told the media. “But what we cannot agree to is a project of this magnitude, in this location, without any proper environmental assessment.”

The speakers alleged a textbook case of deception, obtaining approvals for a low-impact tourist hotel, in one of the most densely populated educational zones in the Katunayake-Seeduwa Municipal Council area, and then transforming it into a heavy industrial plant.

“In an area where thousands of schoolchildren study, to show one thing on paper and build another is a highly fraudulent procedure. It is clear that the real environmental damage and the truth have been hidden from the people,” they said.

With the sea and lagoon winds that sweep across Seeduwa, experts fear these fine particles will not stay confined to the factory walls. They will drift across classrooms, homes, and the Katunayake Free Trade Zone, where thousands of workers, representing all 25 districts of Sri Lanka, work every day.

“The risk is not local. It is national. We are talking about a future generation of children with respiratory illnesses, and workers developing chronic breathing disorders,” one speaker warned.

Then there is the proximity that defies logic, just 500 metres from the Bandaranaike International Airport.

The panel presented a scientific concern that has aviation experts worried: a significant drop in air quality around the airport and its runway, and the severe risk to highly sensitive aircraft engines when they ingest air mixed with cement dust. What is at stake, they argued, is not just health but the economy itself.

“When you weigh it deeply, the economic contribution of an international airport is far higher than that of a cement factory. If international airlines start to avoid Katunayake due to safety and air quality concerns, it will be a fatal blow to our country’s economy,” they emphasised.

A few minutes away lies another victim the Negombo Lagoon and the Muthurajawela wetlands, Sri Lanka’s largest and most sensitive coastal ecosystem.

The panel warned that cement dust settling on the mangrove system could degrade water quality, disrupt the delicate salinity balance, and directly interfere with fish breeding grounds. For the fishing communities of Negombo, whose lives depend on the lagoon, this is an existential threat.

“The lagoon is a nursery. If its water quality drops, fish will not breed. If fish do not breed, an entire fishing community collapses,” they said.

The speakers alleged that while the developers claim to have approvals from various state institutions, many of the mandatory clearances, particularly comprehensive Environmental Impact Assessments and feasibility reports, have not been obtained.

They stressed they are not calling for an end to investment, but for it to be done right.

“We have no objection to this factory being started in another suitable location where it will not cause these environmental impacts, based on proper feasibility and assessment reports. Stop this construction here and move it,” was the unanimous demand.

The appeal has now been directed again to the President, the government, and all responsible state institutions and officials.

As the briefing ended, one image lingered — a school playground, a lagoon, and a towering cement structure rising between them. It is a scary picture for the people of Seeduwa; they asks a simple question: What price are we willing to pay for development that doesn’t breathe?
