COVID-19 jabs can take weeks to work, continued vigilance vital says experts
ECONOMYNEXT – Vaccination against COVID-19 will help bring the death rate down and minimize severe disease but the jab can take weeks to be fully effective and vaccinated people can still spread the virus as asymptomatic carriers, a leading Sri Lankan microbiologist said.
Neelika Malavige, Professor in Microbiology at the Department of Immunology and Molecular Medicine, Faculty of Medicine, University of Sri Jayewardenepura, in a Government Information Department interview urged vaccinated Sri Lankans to stick to health protocols such as masking and regular hand washing.
“No one gets immediate protection right after the jab. It takes about 21 days for the body to produce antibodies after the first dose of AstraZeneca (Covishield). One dose does not provide sufficient protection, which is why we give two,” Malavige said.
Sinopharm also provides considerable protection but only two weeks after the second jab, the professor said. Sri Lanka has decided to give the two doses of the Chinese vaccine four weeks apart.
“In the meantime, you can still get infected and infect others,” she warned.
Taking a new wave of COVID-19 in Singapore as an example, Malavige said vaccinated airport employees were found to have spread the highly transmissible Indian strain of the virus in the city state.
“Everyone at the airport had received the Pfizer jab, so even when they tested positive for COVID-19, they didn’t report severe symptoms. But they still got infected and, as asymptomatic patients, carried the virus into the wider Singaporean society,” she said.
Echoing Malavige, Director of the Infectious Diseases Hospital Dr Ananda Wijewickrama said the primary objective of vaccination is to prevent critical conditions and death.
“People who get the jab can still get infected, but they have a lower chance of developing critical symptoms. It is important to follow health guidelines because we can be vaccinated and still spread it,” he said.
A mutated variant that has only been detected in Sri Lanka suspected to have been mutated from the original COVID-19 virus. The virus has been mainly detected in the Batticaloa district and in the Western Province and was the dominant variant before identifying the UK variant.
According to health authorities, this virus has a lower transmissibility and mortality rate making most of the patients asymptomatic.
Director of Allergy Immunology and Cell Biology Unit of the University of Sri Jayawardenepura Dr Chandima Jeewandara told the privately owned ABC media network that all three vaccines have been proven to be effective against the variants present in the country.
“International research has indicated that the efficacy rate can be changed with these mutations. However, any vaccine that shows an efficacy rate more than 50 percent is considered to be a successful vaccine and all three vaccines are proved to have a higher efficacy rate at the moment,” Jeewandara said.
Jeewandara predicted that Sri Lanka’s ongoing wave of COVID-19, with over 2,500 cases reported a day, will likely be contained by August this year.
“The virus has not changed the way it’s infecting people,” he said.
Vaccination and strict adherence to health protocols will contribute chiefly to containing the spread.
“We should provide at least one type of vaccine to the community. If the vaccine is being given in your area get it immediately, Wear the mask, keep social distance and avoid any gatherings,” he said.
“The next moth is crucial to Sri Lanka. We expect this wave to be controlled by August,” he added.
Jeewandara said there is no guarantee the virus will disappear. Vaccination is the one strategy to take control of the situation, he added.

Gnanasara Thero absconding after SC ruling
Ven. Galagoda Aththe Gnanasara Thero was not at his temple in Rajagiriya when prison officials visited the premises yesterday to take steps following the Supreme Court ruling that nullified the presidential pardon granted to him, police sources said.
Prison officials who visited the temple on Nawala Road, Rajagiriya, were reportedly informed by those present that the Thero’s whereabouts were unknown. The development comes a day after the Supreme Court declared former President Maithripala Sirisena’s 2019 pardon of Gnanasara Thero null and void.
The three-member Supreme Court bench comprising Justices Janak De Silva, Dr. Sobhitha Rajakaruna and Sampath B. Abayakoon held that the pardon was arbitrary, violated the public trust and principles of natural justice, and was made beyond the proper exercise of the President’s constitutional discretion.
The case arose from Gnanasara Thero’s conduct at the Homagama Magistrate’s Court in January 2016 during proceedings relating to the disappearance of journalist and political cartoonist Prageeth Eknaligoda.
The Court of Appeal convicted him on four counts of contempt of court in 2018 and imposed concurrent prison terms amounting to six years. He had served about nine months when Sirisena granted him a presidential pardon on May 23, 2019.
The Supreme Court found that although Article 34 empowers the President to grant pardons, that power is held in trust for the people and is subject to constitutional limitations and judicial review. The Court concluded that Sirisena had effectively acted on the recommendation of the Additional Secretary (Legal) without demonstrating that he had independently considered the relevant material.
Justice De Silva held that the pardon was “arbitrary”, violated public trust and the rules of natural justice, and was ultra vires the President’s powers. The Court consequently found that the decision violated the fundamental right to equality guaranteed by Article 12(1) of the Constitution.
The ruling effectively restores the legal position under the original conviction, leaving Gnanasara Thero without the benefit of the 2019 pardon. The Supreme Court also clarified that a pardon does not erase a conviction or sentence, but merely relieves an offender from serving the sentence to the extent specified in the pardon.
Gnanasara Thero, the General Secretary of the Bodu Bala Sena, had been convicted over his conduct during proceedings concerning the disappearance of Eknaligoda, who went missing in January 2010 and has not been located.
Sandhya Eknaligoda, Prageeth Eknaligoda’s wife, was among those who challenged the presidential pardon before the Supreme Court, alongside the Centre for Policy Alternatives and its Executive Director Dr. Paikiasothy Saravanamuttu.
The detailed account of the judgment indicates that the Court’s ruling primarily nullified the pardon and restored the legal effect of the original sentence, with the implementation of the sentence falling to the relevant authorities.
Police sources said that the Supreme Court, however, did not permanently close the door on executive clemency. It held that a future President could grant Gnanasara Thero another pardon, provided the power is exercised lawfully and after proper consideration of all relevant material.
The Supreme Court has so far overturned three presidential pardons granted to two former Presidents. In January 2024, the Court declared former President Gotabaya Rajapaksa’s pardon of former MP Duminda Silva unlawful and invalid. In June 2024, it invalidated two pardons granted by former President Maithripala Sirisena to Royal Park murder convict Jude Shramantha Anthony Jayamaha — the first in May 2016, which commuted his death sentence to life imprisonment, and the second in October 2019, which released him from prison. Jayamaha, who was convicted of the murder of 19-year-old Yvonne Johnson, remains at large. Most recently, on September 10, 2026, the Supreme Court declared Sirisena’s 2019 pardon of Ven. Galagoda Aththe Gnanasara Thero null and void, ruling that it was arbitrary and inconsistent with the Constitution.

Wrong house targeted in underworld grenade attack: Two children killed
Two children aged 11 and 17 were mistakenly killed and their 55-year-old father injured in an early morning hand grenade attack on Sirisangabo Mawatha on Friday. Police investigations later revealed that the attackers targeted the wrong house during an ongoing underworld clash.
Three police teams have been deployed to investigate the attack, which occurred at around 3 am.
According to police, a man who arrived near the house in a three-wheeler knocked on the front door before throwing a grenade into the premises and fleeing.
The victims were identified as 17-year-old Kasun Rashmika and 11-year-old Duminda Gihan. Their 56-year-old father, Nalin Thusantha Perera, was seriously injured and admitted to the Kalubowila Teaching Hospital.
Police said the injured man’s brother was allegedly a close associate of a drug trafficker known as ‘Sando’ and had also been accused of involvement in drug trafficking.
The brother lives in a house adjoining the one targeted in the attack, and police suspect the grenade may have been thrown at the wrong house.
Police are also investigating information that the attack was allegedly carried out at the direction of several overseas-based drug traffickers, identified as Pandithage Shantha Kumara alias ‘Kos Malli’, Samantha Perera alias ‘Chuwa Samantha’, ‘Kudu Avishka’ and ‘I.D.’
Police said the attack was believed to be linked to an ongoing conflict between two underworld factions, which have targeted each other’s associates in shootings and grenade attacks. More than 20 people have reportedly been killed in such attacks.
Security agencies are also investigating alleged links between one faction and overseas-based criminals including Kanjipani Imran, Unakuruwe Shantha, Dubai Gagana and Handaya.
Security agencies have also received information that overseas-based criminals identified as Kanjipani Imran, Unakuruwe Shantha, Dubai Gagana and Handaya are allegedly behind the supply of firearms and drugs to the faction associated with Kos Malli and Chuwa Samantha.
