Following heated debates and discussions on whether people should receive a single dose or both doses of the Sputnik-V vaccine, a team at the Jayawardenepura University has commenced research on the Russian vaccine's efficacy, Dr Chandima Jeewandara, the Director at Allergy, Immunology and Cell Biology Unit of the University said.
Speaking to Daily Mirror, he said they extended their research to investigate the immune responses in individuals who receive the COVID-19 vaccines and added they would get blood samples from people as a base line today (01) prior to vaccination.
“We believe that we need our own research in this regard to get more clearer picture and that’s why we started a research,
At present, there is no data to support that a single dose of Sputnik-V would give complete protection. However, manufacturers announced that the one-dose version of the vaccine, called Sputnik Light, is authorized for emergency use and provides an efficacy of 79.4 percent," Dr Jeewandara highlighted.
"But the first shot of Sputnik V uses the same common cold virus as the single-dose Johnson & Johnson vaccine, which already has been approved for use in the United States and other countries and has been shown to be safe and effective, with an efficacy of 72 percent in the United States," he said.
"Vaccines work by exposing the immune system to recognisable parts. The immune system then mounts a response. For certain vaccines, it requires two doses, as in some people the first dose alone won’t generate complete immunity. The booster dose (second dose) ensures as many people as possible acquire protection," Dr Jeewandara explained.
"Accordingly, this is applicable to the Sputnik-V as well and that’s why it has been registered as two dose vaccine," he added.
"Moreover, in a pandemic situation, it is not good to keep the vaccines in freezers. Hence, it has to be somehow given to people rather waiting for assurance for a second dose to give the first dose because administering even a single dose will help prevent a death of one person,” Dr Jeewandara pointed out.
He also said that even the World Health Organization (WHO) had recommended that vaccinating with a single dose is a rational way of vaccination rather than waiting for both doses.
“I am of the opinion that it is good to give the Sputnik-V vaccine to eligible people rather than keeping them in freezers so that it will prevent people going into severe disease and death,” he underlined.
“However, we need more data and research to say that the Sputnik-V would provide complete protection with its first dose.” he stressed.
"We believe it would be extremely beneficial to us to have our own data rather than relying studies done by others on vaccines," he opined.
Thus, Dr Jeewandara said the information generated from this study would give them important insights to determine efficacy of Sputnik-V vaccine. (Sheain Fernandopulle)

Now another topic..This will divert the attention of people .

This is just a coverup for stupid statements made by a State Minister and a Cabinet Minster. Why do professional stoop so low?
CHOLMONDELEY PINTO Wednesday, 02 June 2021 06:15 AM
Simply put why are looking at the government for this. This is a scientific matter and needs research asap.
Sam Silva Tuesday, 01 June 2021 07:42 PM
Do we have qualified researchers to determine this theory and the equipment.
Selvakumar Wednesday, 02 June 2021 10:11 AM
In sri lanka still confuse with control the corona virus !!!
Meanwhile in SL Tuesday, 01 June 2021 08:14 PM
Why the Health authorities are not giving a clear cut idea about it. According to Dr Jeewandara, no data to support that a single dose of Sputnik-V would give complete protection. But Cabinet Spokesman Keheliya Rambukwella says something else.
Saman Tuesday, 01 June 2021 08:22 PM
This is great. Our doctors are among the best in the world. We should disregard advice from backward countries like India and trust our doctors and also Chinese doctors , who have proven to also be among the best in the world. Sri Lanka should emulate China model soon.

I have registered and given blood for a research being conducted on immune response to Sinopharm by a known medical research institute with known medical experts. These type of researches are needed and only People with science background will understand the value

Sputnik-light is just the 1st dose of the "normal", two-dose sputnik vaccine. Unlike the Oxford (AstraZeneca) vaccine, the "normal" Sputnik vaccine's 1st and 2nd doses are different. So you can not give the 1st dose again as a 2nd dose. So, obviously, there is no point in saving the 1st dose to give as the 2nd dose.
BuffaloaCitizen Tuesday, 01 June 2021 09:07 PM
Wow, a country that cannot order adequate vaccines for its citizens is going to take up research. This is like our one and only space scientist who is refusing to join NASA. I like the way Sinhalese think of themselves.

Give those people in Governmwnt to read this. They seem to be disregarding the opinion of experts..

If you do not understand this, please do not misinterpret
What a silly idea Wednesday, 02 June 2021 02:01 AM
Very stupid. The Russian company has already done it. We MUST believe in that. Also to find out the efficacy conclusively it will take at least 6 months. It will very late by then.
Nathura Kodi Wednesday, 02 June 2021 02:49 AM
Too long; still good reporting. Otherwise people and authorities will not understand..
George Wednesday, 02 June 2021 02:52 AM
This should have been looked into before it’s brought to the country. Now, we have to wait another months until results of this research comes out
John Nirmak Wednesday, 02 June 2021 02:55 AM
Sir failed..Not being able to manage it properly. Now, all of a sudden a research..
lal Wednesday, 02 June 2021 03:25 AM
Even the best vaccine mRNA Pfizer and Moderna they give 2 shots.
K Perera Wednesday, 02 June 2021 05:16 AM
Just another diversion... Gameleya (developer of the Russian Vaccine) had done enough tests and released all details in December 2020. There's nothing more to study. I can accept if these guys were testing the crap Chinese vaccine as the Chinese haven't released their own results for quite obvious reasons.
adwani Wednesday, 02 June 2021 07:20 AM
First of all, nobody, NOBODY in Sri Lanka knows the meaning of Covid 19 and Universally, there is nothing called Covid 19, it is a secret introduced to make vast amount of money, by selling masks, vaccine, etc.
James Wednesday, 02 June 2021 09:03 AM
Russia have recently introduce "Sputnik Light " which is Single Dose. What we have here in Sri Lanka is "Sputnik V" which is two doses. What these politically motivated Doctors and Cabinet spokesman doing is trying to gaslight the masses with there word salad. Don't push your inability to manage a vaccine program on people with your bogus study . This government don't have money no matter how much louder Johnston screams!!!!
UKSL doctor Wednesday, 02 June 2021 11:07 AM
What nonsense . Research to be done only if we produce the vaccine. Russia has already done it and proved it efficacy. Our attitude is we talk big. We do not have the expertise. Please don't waste time vaccinate everyone.
