The AstraZeneca/Oxford COVID-19 Vaccine was developed by AstraZeneca PLC, a multinational pharmaceutical company.

Who is the manufacturer?

AstraZeneca PLC is a British–Swedish pharmaceutical and biopharmaceutical company. It owns a large portfolio of products for major disease areas.

And back in December 2020, it has developed its own COVID-19 Vaccine.

How does it work?

The AstraZeneca/Oxford COVID-19 Vaccine was crated from a weakened version of a common cold virus that has been modified to behave more like the coronavirus. It works to stimulate the immune system to begin producing antibodies that prepare it to attack any coronavirus infection.

Who can take the AstraZeneca/Oxford COVID-19 Vaccine?

Following recommendations, the AstraZeneca/Oxford vaccine will only be used for individuals between 18 and 64 years old. Due to a lack of data regarding this vaccine, there is no clear information on the efficacy of the vaccine in people over 65, pregnant, and breastfeeding women.

Don’t take the vaccine if you:

  • Have ever had an allergic reaction following any other vaccine.
  • Suffer from extremely high temperature (over 38 °C).
  • Have a bleeding, bruising problem, or if you are taking medication that thins the blood.
  • Suffer from immune system problems (immunodeficiency)
  • Are taking medicines that weaken your immune system.

If you are not sure, talk to your doctor, pharmacist, or nurse.
