GENEVA, Dec 7 (BNC Network) - As the novel Corona virus has turned out to be unpredictable in its behaviour for different age groups and geographies, WHO and scientists are closely monitoring the results of the vaccine.
The story of vaccine is not over with the administration of the first batches to people, said a WHO official responding to a question from BizNewsConnect during a virtual global media conference this evening.
Analysis of data so far shows that the efficacy of the vaccine is similar among the age groups – old and young – said the official. But she hastened to point out that the vaccine has not been tested among the people above the age of 80 years.
Tests on different populations and sub-groups are on and the age is one of the primary attributes, she said.
Earlier, WHO Director General Dr Tedros Adhanom Ghebreyesus said "As countries plan to roll out COVID19 vaccines in the coming weeks and months, we urge them to prioritize vaccinating those most in need, based on the Values Framework and Population Prioritization Roadmap issued by WHO’s Strategic Advisory Experts Group on Immunization.”
In the initial stages of rollout, with only a small proportion of a country’s population immunized it’s vital that governments, communities and individuals continue using proven public health tools, he said.
As supply increases, the next groups would include those who have higher risk of severe disease because of their underlying conditions, and marginalized groups at higher risk.
"We are still learning how strong immune responses are in different populations and for how long this immune response lasts,” Dr Tedors said and explained that WHO continues to work with our global networks to better understand the proportion of the world’s population that has been exposed to this virus and how long immunity lasts in people who have been infected.
"Despite their limitations, their results are fairly consistent: they tell us that most of the world’s population remains susceptible to infection with the COVID19 virus," Dr Tedors pointed out.
