Covishield vaccine induces immunity for at least one year following a single dose

Strong immune responses following either a late second dose or a third dose

by Emme Haddon

In early March 2021, I received my first shot of Covishield but began to get a little worried when the recommended three-month time frame had passed for the second dose with no sign of the promised shipment from India. Finally, in the first week of August, some months later, after what seemed like an interminable wait, I was fortunate enough to secure my second dose of Covishield, along with 490,000 or so others.

The findings of a study of Vaxzevria, the European brand name for the UK’s AstraZeneca vaccine of which the Indian-manufactured Covishield is biologically identical, from the Oxford-led COV001 and COV002 trials by researchers at the University of Oxford, released on June 28, 2021 on the pre-preprint server of the Lancet, demonstrated that antibody levels remain elevated from baseline for at least one year following a single dose.

Furthermore, a 45-week dosing interval between the first and second dose of Covishield, resulted in an 18-fold increase in antibody response, measured 28 days after the second dose. Antibody titers (test determining level of antibodiess in the blood) were four times higher than with a 12-week interval, demonstrating that a longer dosing interval is not detrimental but can derive stronger immunity. The analysis included volunteers aged 18 to 55 years who were enrolled in COV001 and COV002 trials and had received either a single dose or two doses of COVID-19 Vaccine AstraZeneca.

In addition, a third dose of Vaxzevria given at least sixmonths after a second dose, boosted antibody levels sixfold, maintained T cell response and also resulted in higher neutralising activity against the Alpha (B.1.1.7, ‘Kent’), Beta (B.1.351, ‘South African’) and Delta (B.1.617.2, ‘Indian’) variants. Both the late second dose and the third dose of Vaxzevria were less reactogenic than the first dose.

It seems that those of us who patiently endured a five-month wait for their second dose of Covishield, may in fact, be better protected than those who, by whatever means they felt necessary, managed to secure their second dose in the previously recommended three-month dosing interval, before supplies ran out. As the old adage goes: good things come to those who wait springs to mind!

The release of the findings of a second study on July 28. 2021, by researchers from the University of Oxford, concluded that the risk of the rare blood clotting thrombocytopenia, venous thromboembolism and arterial thromboembolism after receiving first doses of AstraZeneca or Pfizer COVID-19 jabs is far lower than from the actual virus.

Rates of venous thromboembolism were eight times higher after a diagnosis of COVID-19 infection compared with the expected rate. Many developed countries limited AstraZeneca’s use to older adults because of concerns about an elevated risk of blood clots affecting the younger population. These findings should allay any fears about the vaccine’s safety.

Results from the Canadian Immunization Research Network with support from the Public Health Agency of Canada and the Canadian Institutes of Health Research, published as a pre-print on July 23, 2021, showed that one dose of Vaxzevria (Covishield) was 82% effective against Beta/Gamma and 87% and 90 % effective against the Delta (B.617.2, ‘Indian’) and Alpha (B.1.1.7, ‘Kent’) variants’ hospitalisation or death.

Research into the coronavirus is on-going and it important to ensure that officials keep abreast of new developments and plan accordingly. In countries such as Sri Lanka with limited resources, hard hit economically by Covid-19, where the majority of those under the age of 30 have yet to receive a first vaccine, the findings that Covishield’s antibody levels remain elevated from baseline for at least one year following a single dose, with increased immunity provided as a result of a longer dosing interval are potentially game-changing.

The Delta virus variant has changed the shape of the pandemic. At a time when the vaccination program is struggling to keep up with rapid transmission of the Delta variant, any Covishield vaccines kept aside for second doses, might be better utilised now as first doses to prevent hospitalizations and deaths in those higher risk as yet unvaccinated groups.

Easter Sunday carnage: WR asks AG to question Dappula on ‘grand conspiracy’ claim

Published

on

Former Justice Minister Dr. Wijeyadasa Rajapakshe, PC, yesterday urged the Department (CID) to question former Attorney General Dappula de Livera, PC, regarding his claim that the 2019 Easter Sunday carnage was a grand conspiracy.

Dr. Rajapakshe, a former President of the Bar Association of Sri Lanka, pointed out that the former Director of the Directorate of Military Intelligence (DMI) and the ex-head of State Intelligence Service (SIS) had been arrested under the Prevention of Terrorism Act (PTA) on the basis of unsubstantiated allegations levelled by a fugitive from the Sri Lankan law that Gen. Sallay masterminded the Easter Sunday carnage.

The CID arrested Sallay on February 25, 2026, at Peliyagoda.

Attorney General Parinda Ranasinghe, (Jnr), PC, could not under any circumstances further delay seeking an opportunity for the CID to question de Livera. The ex-Minister said so yesterday (15) when The Island sought his explanation regarding the claim he made in Kandy on Sunday that de Livera alleged a grand conspiracy after the then President Gotabaya Rajapaksa declined to grant him a one-year extension.

Ex-parliamentarian Rajapakshe quoted President Rajapaksa as having told him that de Livera was told of his inability to grant the outgoing AG’s request. However, the then government offered him the opportunity to serve as Sri Lanka’s High Commissioner in Canada. He declined that offer.

Responding to The Island queries, Rajapakshe said that though de Livera succeeded in thwarting the Terrorist Investigation Department (TID) from questioning him over his claim made on the eve of his retirement, in May, 2021. According to him, when a major controversy erupted over De Livera’s claim, the TID had been sent to record his statement.

Having evaded the police and successfully moved the Court of Appeal against the TID, the former AG sent a lawyer to the TID on his behalf. That lawyer declared that a seven-paged legal objection to the matter in question has been submitted to the TID.

“Archbishop of Colombo Malcolm Cardinal Ranjith and all those who had been demanding justice for Easter Sunday victims should urge AG Parinda Ranasinghe (Junior), PC to record de Livera’s statement. The ex-Minister said that the Leader of the House, Minister Bimal Ratnayake, disclosed that SSP Shanie Abeysekera and Senior DIG Ravi Seneviratne had been appointed Director, CID and Secretary to the Public Security Ministry, respectively, on the Cardinal’s advice. Therefore, the Cardinal should stress the urgent need to record the former AG’s statement.

Dappula de Livera received his appointment on 10 May, 2019, just weeks after the Easter Sunday carnage, and retired on 25 May, 2025.

On the eve of his retirement, alleging that there had been a grand conspiracy, de Livera said that the information by the SIS with times, targets, places, method of attacks and other information proved the conspiracy. He said that the identities of those involved in the grand conspiracy must come by the way of evidence.

Wijeyadasa Rajapakshe said that investigations into the Easter Sunday carnage couldn’t be brought to a successful conclusion until de Livera revealed what he knew about the grand conspiracy, mastermind or whatever various interested parties chose to call the attacks.

The government sent a CID team to Paris to record a statement of Azad Moulana, a fugitive seeking asylum in Switzerland and who implicated Sallay in the Easter Sunday attacks. “This matter is so serious de Livera must consider volunteering to assist the investigation,” ex-lawmaker Rajapakshe said, challenging all those genuinely concerned about the inordinate delay in bringing the high profile investigation into a conclusion to push for immediate questioning of de Livera.

Having spearheaded the Easter Sunday investigation at the onset of the probe, de Livera could shed light on the alleged conspiracy if he really meant his declaration on the eve of his retirement, Dr. Rajapakshe said.

Beijing Capital Airlines to resume direct flights between Beijing and Colombo in September this year, restoring an important air link and strengthening tourism, business, and people-to-people connectivity. This service will complement the existing 23 weekly flights between Mainland China and Colombo.

This was announced at Sri Lanka tourism briefing and networking reception held recently in Beijing. Sri Lanka embassy in Beijing with the support of the Sri Lanka Tourism Promotion Bureau (SLTPB) held the event that brought together over 120 representatives from China’s travel trade, media organizations, tourism-related investment sector, airlines, content creation industry, and Meetings, Incentives, Conferences and Exhibitions (MICE) sector.

Among the participants were representatives of leading Chinese travel companies and media organisations, including China Tourism Group Travel Services Corporation Limited, China International Travel Service (CITS), China Youth Travel Service (CYTS), Spring Tour, Mafengwo, Xinhua News Agency, People’s Daily, Global Times, Guangming Online, and China Times, together with representatives of SriLankan Airlines and Beijing Capital Airlines.

The event, led by Deputy Chief of Mission (DCM), Poornima Gunasekera marked the resumption of the Embassy’s direct engagement with China’s travel trade and media community after a considerable period and provided a platform to outline new initiatives aimed at strengthening tourism cooperation between Sri Lanka and China ahead of the 70th Anniversary of the establishment of diplomatic relations between the two countries in 2027.

In her keynote address, the DCM highlighted the longstanding historical ties between Sri Lanka and China, dating back more than 2,000 years through the ancient Maritime Silk Route, and stressed tourism as a key channel for deepening people-to-people exchanges. She noted Sri Lanka’s strong tourism recovery, with over two million international arrivals in 2025, and reaffirmed the country’s image as a safe, peaceful, and welcoming destination. She also highlighted the Government’s expanded visa-free entry programme covering 40 countries, including China, designed to make travel easier and more convenient.

She emphasised Sri Lanka’s unique tourism offering, which combines exceptional diversity within a compact geographical area. Within just 65,610 square kilometres—about four times the size of Beijing—visitors can experience beaches, UNESCO World Heritage Sites, wildlife safaris, tea country, wellness tourism, adventure activities, cultural heritage, gemstones, and authentic Sri Lankan hospitality. She also underlined improved connectivity, noting that a direct flight from Beijing to Colombo takes around seven hours, making Sri Lanka a convenient option for Chinese travellers within broader Asian travel itineraries.

A delegation of the United Nations Subcommittee on Prevention of Torture (SPT) is in Colombo. The SPT’s second visit, from 15 to 24 June 2026, takes place amidst the ongoing debate over the NPP government’s decision to bring in a new anti-terrorism law in place of the Prevention of Terrorism Act (PTA) enacted in 1979.

Some political parties, and civil society groups, have criticised the NPP move as the ruling party, during the presidential and parliamentary polls campaigns, promised to abolish the PTA.

The SPT conducted its first visit to Sri Lanka in April 2019, following Sri Lanka’s accession to the Optional Protocol to the Convention against Torture (OPCAT) in December 2017. Upon accession, the Human Rights Commission of Sri Lanka (HRCSL) was designated as the National Preventive Mechanism (NPM), under OPCAT, by the Government of Sri Lanka.

The Foreign Ministry said that the four-member SPT delegation was scheduled to hold meetings at ministerial level, and engage with senior officials of relevant ministries, departments and institutions. The delegation would also meet representatives of the Human Rights Commission of Sri Lanka and members of civil society, the ministry said.

“The Government of Sri Lanka will engage with the Subcommittee in an open, constructive, and transparent manner, consistent with its policy of continued engagement with the United Nations, and in fulfilment of its Treaty Body obligations undertaken voluntarily and enshrined in relevant international instruments, in accordance with the Constitution.

The delegation will comprise Ms. Aisha Shujune Muhammad (Maldives) (Head of delegation); Jakub Julian Czepek (Poland); Ms. Anica Tomsic (Croatia); and Nika Kvaratskhelia (Georgia). They will be accompanied by officials of the SPT Secretariat in Geneva, Switzerland.”
