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

Speaker’s personal secretary accused of interference with ongoing bribery investigation
SJB Gampaha District MP Harshana Rajakaruna yesterday told Parliament that the Speaker’s Personal Secretary had written to the Secretary-General of Parliament seeking information on a complaint lodged with the Commission to Investigate Allegations of Bribery or Corruption (CIABOC) by a former Deputy Secretary of Parliament against the Speaker. Rajakaruna called for an immediate investigation into what he described as interference with an ongoing probe.
Raising the matter in the House, Rajakaruna said he had formally requested the Commission to initiate an inquiry into the conduct of the Speaker’s Personal Secretary, Chameera Gallage, questioning the authority under which such information had been sought.
Rajapakaruna tabled in Parliament a copy of the letter allegedly sent by Gallage to the Secretary-General requesting details of the bribery complaint.
Addressing the House, Rajakaruna said that the letter, sent two days earlier, had sought “full details” of the complaint against the Speaker. He maintained that seeking such information amounted to interference with an investigation and constituted a serious offence under the Bribery Act.
“The Speaker’s Secretary has no right to interfere with the work of the Bribery Commission. Under what law is he acting? What authority does he have? The Speaker, like everyone else, is subject to the law of the land,” Rajakaruna said, urging the Commission to take immediate action.
He noted that the Bribery Act treated the obstruction of investigations and the destruction of documents relating to such inquiries as serious offences punishable by law, and said he believed the Minister of Justice would concur.
The allegations sparked sharp reactions in the Chamber, as Opposition members called for accountability and due process in relation to the complaint against the Speaker.

Govt: Average power generation cost reduced from Rs. 37 to Rs. 29
The Ceylon Electricity Board has managed to reduce the average cost of electricity generation from Rs. 37 per unit to Rs. 29, marking a 22 percent reduction, Minister of Power and Energy Eng. Kumara Jayakody told Parliament yesterday.
Responding to an oral question raised by Opposition MP Ravi Karunanayake, the Minister said that electricity tariffs cannot be reduced unless the cost of generation is brought down.
“You cannot reduce electricity tariffs without reducing the cost of generation. What we are currently doing is buying at a higher price and selling at a lower price. When we assumed office, the cost of purchasing and generating electricity was Rs. 37 per unit. We have now managed to bring it down to Rs. 29, a reduction of 22 percent.
Our target is to further reduce this to Rs. 25. Once that is achieved, we will reduce electricity tariffs by 30 percent within three years, as we promised,” Minister Jayakody said.
He added that the government has already formulated a long-term generation plan to further expand the country’s power generation capacity.
According to the Minister, key measures include increasing the absorption of renewable energy into the national grid, expanding the national transmission and distribution network, introducing renewable energy storage systems, and constructing thermal and liquefied natural gas (LNG) power plants to replace aging facilities and meet future demand.
He also said that steps would be taken to enhance the capacity of existing hydropower plants as part of the broader strategy to ensure energy security and reduce long-term electricity costs.
