The COVID-19 vaccine has been successfuly developed by researchers at Oxford University in the United Kingdom.
They have confirmed that the vaccine is effective and safe.
Medical Journal The Lancet has published results of the vaccines that was administered to half of the 1,077 candidates.
The article said that
the vaccine strengthens the body’s immunity against the coronavirus.
Let me tell you about it.
First out of the millions of viruses for the common cold, scientists selected on that is very weak.
This virus can cause infection in Chimpanzees but it can not infect humans.
This is because they have genetically modified the virus.
It was then used in the vaccine to help defend the body from COVID-19.
According to the results that were published, the vaccine which has been named ‘ChAdOx1 nCoV-19
was able to produce Antibodies and T-cells.
Let me tell you about it.
The vaccine increases the production of Antibodies by the blood and defends the body from diseases.
T-cells are part of the immune system.
Due to the vaccine their production increases and they attack and kill any infections that enter the body.
When the vaccine was injected into the patients, 14 days later the number of T-cells started increasing in the patient’s body
and 28 days later antibodies started increasing in their bodies.
10 people were given double doses of the vaccine
and because of this their immunity became even more strong.
The Oxford vaccine has been proven to be safe.
During the trial, the vaccine did not cause severe reactions
but 70% of the people did get little fever and headache which were managed with paracetamol.
Even though the results are promising, the vaccine is still not ready for use.
The vaccine has to complete Phase 3 of testing in which more than 10,000 people all over the UK and other countries will be tested.
Data from this phase will confirm how effective and safe the vaccine is.
It may be ready by September or October.
