Indian fishers riled by SL moves to create new fish breeding grounds

Fishermen from Rameswaran will hold a protest today (16) against Sri Lanka’s decision to submerge 20 old buses in the seas off Jaffna to create breeding grounds for fish.

Members of 17 fisheries associations in Tamil Nadu and Rameswaran claim that this will affect their yield as more fish will be attracted to the breeding grounds created by submerged buses.

The Ministry said that sinking those buses was nothing new and that such buses provided a hard surface for invertebrates to live on, some of which could not live on the sand bottom that is naturally there.

“Some fish are not fast swimmers, so they need a structure to provide both food and shelter; they wouldn’t, for example, be able to outswim a shark, but they could duck into the shelter instead,” a Sri Lankan fisheries association representative said.

However N. Devadas, the head of the Indian fishermen’s association in Rameswaram, said that they would also hand over a petition against that decision to the Sri Lankan government. Sri Lanka has been submerging old SLTB buses in the deep sea for many years as a part of the Deep Sea Fish Development Project.

Even four months after first jab antibodies generated by Covishield vaccine remain active – expert

Published

By Rathindra Kuruwita

A significant amount of antibodies created by the Covishield COVID-19 vaccine remained even 16 weeks after receiving the first jab, Dr. Chandima Jeewandara of the Allergy, Immunology and Cell Biology Unit, Department of Immunology Molecular and Molecular Medicine of the University of Sri Jayewardenepura said yesterday.

“We studied this because it was a serious issue due to hundreds of thousands of people have not received the booster doses yet. Our research shows that a significant amount of antibodies remains in those who received the first dose. This is good news and I think we can give them the second dose. But we have to conduct tests.”

Dr. Jeewandara said they would soon release a report on antibodies that developed due to the Sputnik-V vaccine, and a similar report on the Moderna vaccine too would be released in a month or two.

Dr. Jeewandara said that 500 Sputnik-V recipients and 600 Moderna recipients were being studied.

Commenting on a recent study by the department on the development of antibodies by those given the Sinopharm vaccine where it was found that vaccine induced antibody responses in over 95% of individuals, similar to levels seen following natural COVID-19 illness, Dr. Jeewandara said that the study had addressed a key concern people had about Sinopharm.

“One of the biggest problems is that we have little data on Sinopharm. This study tries to fill that,” he said.

Dr. Jeewandara said that the university had started measuring efficacy and antibodies from vaccines since Sri Lanka started administering them. The first vaccine they started studying was Covishield, he said.

“Let me explain the process. We take a blood sample before vaccination. We do that to identify antibody levels before vaccination. In Sri Lanka most people who contract COVID19 don’t develop symptoms. So we do this as a baseline blood test. Then we get a second sample before the second jab is given and a third sample at a time the manufacturer recommends as the best time to check antibodies.”

In the case of Sinopharm, the third sample was taken two weeks after the second jab. The researchers look at the level of antibodies and T-cell response because they are the two main tools to fight or prevent the virus or prevent serious illness, he said. A person can either get antibodies from contracting the virus or through vaccination, Dr. Jeewandara said.

“These are not efficacy tests. Efficacy is measured in a controlled clinical trial and is based on how many people who got vaccinated developed the ‘outcome of interest’ (usually the disease) compared with how many people who got the placebo (dummy vaccine) developed the same outcome. What we did was to test antibodies but this hints at vaccine efficacy too. Immunity and protection tend to be similar in both tests.”

Dr. Jeewandara said that Sri Lanka was an interesting case study because most Sri Lankans were genetically similar and that one variant usually dominates the country. However, Sri Lanka used several vaccines, giving the country an excellent opportunity to find out what vaccine was best.

“We also studied Covishield and over 90% of people vaccinated with it had developed antibodies,” he said.

“Based on estimates of the assessment of damages made by an assessment committee, compensation of up to a maximum of Rs. 2.5 million was paid to home appliances, and to buildings and equipment of small and medium scale business that do not exceed an annual income of Rs. 10.0 million and that are not benefited under any other insurance coverage. Further, an advance of Rs. 10,000 was also given to the victims to quickly repair the damaged houses due to natural disasters until the damage assessment is done. This money was paid through National Insurance Trust Fund and Provisions from the Treasury. Rs. 287.9 million and Rs. 320.7 million were paid from those two sources between April 2019 and December 2020,” the report said.

The report highlighted that a large number of people are being affected by dry weather and that many people suffer being unable to meet their daily drinking water needs. In 2017, 1,113,858 families were affected by dry weather, in 2018, 567,987 families were affected, and in 2019, 312,383 families were affected.

New guidelines for weddings soon – Health Ministry

Published

By Rathindra Kuruwita

The Health Ministry will soon amend health guidelines on weddings after hundreds of complaints had been received on behaviour that could lead to superspreader events, a ministry spokesman said.

“We have allowed weddings to take place with 25% seating capacity or a maximum of 150 people but drinking and dancing are not permitted. We have received many complaints of drunk people and other guests dancing on fully packed dance floors. Covid-19 guidelines are not followed” he said.

Given this development the Ministry would soon amend the guidelines so certain activities can’t be carried out, he said.

Earlier yesterday General Shavendra Silva, Head of the National Operation Centre for Prevention of COVID 19 Outbreak (NOCPCO) said wedding guests were behaving irresponsibly and there was a high possibility wedding clusters emerging.

“We have set the maximum number of people who can attend a wedding at 150 but in some areas many more people attend wedding receptions. We have allowed these weddings to take place on humanitarian grounds but if people abuse freedom given to them we will all be in trouble. Over 1,500 Covid-19 cases are still reported daily.”
