The Oxford-AstraZeneca is made from the weakened version of a common cold virus known as an adenovirus gotten from chimpanzees. It was modified to contain a genetic material shared by the coronavirus – although it can’t cause any illness.
Once injected, it programs the body’s immune system to fight the real virus.
Does the vaccine protect against new variants of the Covid virus?
Professionals are presently studying existing coronavirus vaccines to find out how they work against the new and mutated variants of the virus.
There is limited evidence about protection against other variants, identified in Brazil and South Africa.
A study that used 2,000 people suggests that even though the Oxford-AstraZeneca vaccine may offer limited protection against mild and moderate disease caused by the South Africa variant. It could still protect against severe disease.
Other countries take on the AstraZeneca vaccine
After a study looking at 86 similar cases in the European Union, the European Medicine Agency concluded the advantages of the vaccine surpassed the risk and that there was no definite causal link.
However, Denmark stopped its AstraZeneca rollout completely – and the four countries, Germany, Spain, Italy, and Ireland have suspended the usage of the vaccine in people under 60.
