WHO insists on the Oxford-AstraZeneca vaccine despite reservations from other nations 

Despite concern from other firms, the health agency has continued to support the Oxford vaccination. It says its trials proved that the vaccine could protect against different strains. 

WHO backs AstraZeneca vaccine 

The World Health Organization has said it won't back down in recommending the vaccine even if some nations say it doesn't work on their variants. On Monday, top South African health experts have said that vaccines are less potent against their variants.

The WHO has also insisted that people over age 60 can use it despite several European nations, particularly France. When the vaccine's dosage is spaced accordingly, it allows the vaccine to work better. The Oxford vaccine has continued to be potent and seen as a global vaccine because it is affordable and can be stored easily in the fridge.

Also, this vaccine has been a subject of significant controversy because it is widely reported to be less effective against other strains. Also, some countries are not sure if it works well with the older population. The advisory group of health analysis on infectious disease has been working on the vaccine trials. 

South African position on Oxford vaccine inconclusive - WHO director 

Early results show that it has a 65% potency against all strains. However, South African doctors say it offers '' little efficiency '' for mild cases in the young population. WHO's director, Dr. Katherine  Brien, insisted that the South African results were not conclusive. 

The new strain is mutations that make the virus escape vaccines and increases the virus strength. However, Oxford doctors have said that their vaccine will prevent any COVID-19 from falling sick or going to intensive care. '' We have no reason to question its administration as our research shows it works with all strains,'' Dr. Alejandro Cravioto said. 

However, countries like France and Germany have said there is no data that this vaccine protects older adults.
