Sinopharm found to be less effective in older individuals

By Ashanthi Warunasuriya

The Sinopharm vaccine appeared to be less effective in older Covid positive vaccinated individuals, according to data from a study conducted in Bahrain, Professor Neelika Malavige said.

Professor Neelika Malavige from the Department of Immunology and Molecular Medicine at the Sri Jayawardenepura University tweeted saying the study had found that the percentage of deaths among all PCR positive post-vaccination COVID-19 cases among recipients of the Sinopharm vaccine was 0.46% (i.e, 112 deaths) versus 0.15% for Pfizer/BioNtech (i.e., 3 deaths) and 0.03% for AZ/Covishield (1 death).

She added that the authors have however concluded that the four vaccines were effective in reducing all four outcomes (infections, hospitalizations, ICU admissions and deaths) in vaccinated compared to unvaccinated individuals, prior to, and during the period when the Delta variant became dominant in the country.

The data published by Research Square notes that after censoring early vaccine recipients of Sinopharm vaccine, compared to Pfizer/BionTech recipients, individuals vaccinated with Sinopharm had a higher risk of post-vaccination infections, hospitalizations, ICU admissions and deaths, especially in those above 50 years old.

The overall findings support the value of vaccination in preventing COVID-19 related events even with the advent of the Delta variant. The data support the urgent need to expand vaccination access around the world, and may serve to guide the choice of vaccines in the context of the Delta variant. (Colombo Gazette)


  1. Former Foreign and Finance minister Mangala Samaraweera had first and second Pfizer vaccines, still he died. Data can be manipulated easily. If the research analysts are western puppets, they start the research with preconceived results that would be beneficial to the Western countries. The West has the ability to make you to believe according their agendas. Around 100 – 200 million people were eliminated to take over North America and Australasia. But this data systematically omitted to safeguard the western interests, especially to occupy the moral high ground. The West made you to believe that Iraq had WMD and had to be invaded the country to save the world. It also made you believe that invading Libya is extremely vital to implement democracy to make Libya as a glorious country in Africa. But the truth is the West has been looting those countries, now those countries are going backward. Above all, I have got to know the West through my own experience. I have Australian undergraduate and postgraduate qualifications with no criminal records, but I can not get a job in my field, not even a basic customer service job in petrol stations. I can’t even get finance to buy used car to drive Uber. I spent most of my time in libraries to develop my knowledge to enlighten the world. For the West this is more than a criminal offence. The Australian Government and media never allowed my voice to be heard. This is why I believe that enlighten the world is very important. The battle goes on. I continue to prove my knowledge, the Australian Government continues to undermine my credibility. Let’s see how far this is going to go.
