The Oxford–AstraZeneca COVID-19 vaccine is popularly known as AZD1222.
The Medicines and Healthcare products Regulatory Agency (also known as the MHPRA) has asserted that everyone who shows any of the following symptoms four or more days after collecting the Oxford-AstraZeneca vaccine should seek immediate medical advice:
- A drastic or long persistent headache
- Dimmed vision
- Chest pain
- Shortness of breath
- Swollen legs
- Long-lasting abdominal pain
- Unusual skin bruising
How the Oxford-AstraZeneca vaccine works
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.
France on the other hand recommends that the vaccine is only be given to those aged 55 or over, while Australia says people aged under 50 should get the Pfizer jab instead.
Testing for Coronavirus
So far, there are currently two types of COVID-19 tests that can be carried out when a patient shows symptoms of the virus: diagnostic tests and IgG Antibody tests.
The diagnostic test is conducted to test if someone is infected with the coronavirus. Health care professionals conduct this test by looking for pieces of the virus in a patient’s sample of saliva or mucus. The test will tell if a person is infected on the day of the test.
The IgG test on the other hand is a simple blood test that is used to assess the level of Immunoglobulin G antibodies in a patient’s blood.
The IgG testing method measures antibody levels and provides a quantitative result that will help medical professionals in the understanding how an individual is recovering from Coronavirus.
Similarly, the tests can also be used to monitor a person’s immune response to vaccines and check a person’s antibody level to help analyze eligibility and potency for convalescent plasma donations.
Why is testing carried out?
- They are carried out to see if a person has an infection or is protected from getting an infection.
- To help diagnose immunodeficiency
- It may be done as part of an evaluation for allergies or autoimmune conditions
