Vaxzevria COVID-19 Vaccine AstraZeneca 2022
The Vaxzevria - AstraZeneca COVID-19 (AZD1222) (ChAdOx1 nCov-19) (C19VAZ) vaccine is made from a virus (ChAdOx1), a weakened version of a common cold virus (adenovirus). In addition, genetic material has been added to the ChAdOx1 construct, used to make proteins from the SARS-CoV-2 beta coronavirus called Spike glycoprotein (S). After vaccination, the surface spike protein is produced, priming the human immune system to attack SARS-CoV-2 if it later infects the body.
This protein is found on the surface of SARS-CoV-2 and plays an essential role in the infection pathway of the coronavirus. SARS-CoV-2 uses its spike protein to bind to ACE2 receptors on human cells to enter the cells and cause an infection. After vaccination, the surface spike protein is produced, priming the immune system to attack the coronavirus if it later infects the body and causes COVID-19. However, Vaxzevria does not contain coronavirus and cannot cause COVID-19, says the European Medicines Agency (EMA).
On June 28, 2021, the University of Oxford published on the preprint server of The Lancet a study that demonstrated that antibody levels remain elevated from baseline for at least one year following a single dose. In addition, a sub-analysis from the Oxford-led COV001 and COV002 trials with Vaxzevria found strong immune responses following either a prolonged second dose interval of up to 45 weeks or following a third boosting dose.
The EMA authorized Vaxzevria in February 2021. On March 26, 2021, the EMA posted 'Vaxzevria' as the new name for COVID-19 Vaccine AstraZeneca. The HUN-VE phase III clinical trial conducted across three continents published an interim analysis on November 25, 2021, the determinate the ChAdOx1 nCoV-19 showed significant 70.4% effectiveness against SARS-CoV-2 virus infection after two doses. In addition, on December 16, 2021, the NEJM published an ORIGINAL ARTICLE: Phase 3 Safety and Efficacy of the AZD1222 Vaccine - CONCLUSIONS: AZD1222 was safe and efficacious in preventing symptomatic and severe Covid-19 across diverse populations that included older adults in the significant phase 3 clinical trial.
And the UK's Health Security Agency confirmed on Dec. 10, 2021, that a limited study found three doses of the AstraZeneca vaccine were around 75% protective against the Omicron virus variant. On May 23, 2022, Vaxzevria was granted approval by the EMA as a third dose booster in adults. The WHO published: The Oxford/AstraZeneca (ChAdOx1-S [recombinant] vaccine) COVID-19 vaccine: what you need to know, on June 13, 2022.
On July 13, 2022, an expert review of data from 79 real-world studies showed that Vaxzevria and the available mRNA COVID-19 vaccines provide equally effective protection against hospitalization and death from COVID-19 following two doses. The study findings were reported by Expert Review of Vaccines on June 30, 2022.
AstraZeneca's Vaxzevria (AZD1222) (ChAdOx1 nCov-19) (C19VAZ) vaccine's Accession Number: DB15656. The UNII Preferred Substance Name: B5S3K2V0G8. A listing of clinical trials is updated.
AstraZeneca COVID-19 Vaccine Versions
Three versions of the Oxford-AstraZeneca vaccine are produced, including Vaxzeria, AstraZeneca-SKBio (Republic of Korea), and the Serum Institute of India (CoviShield) have been Listed for emergency use by WHO. The Australian government published on November 19, 2021, patient fact sheets in various languages about what to expect after being given the Vaxzevria (AstraZeneca) COVID-19 vaccine. It is authorized in Australia, Canada, Europe, the U.K., and over 100 countries and is Listed by the WHO. About two billion doses were distributed in 2021.
Vaxzevria should be administered intramuscularly as two 0.5 mL doses given four to 12 weeks apart, with an interval greater than eight weeks being preferable to maximize its efficacy. On September 17, 2021, the EMA's recommendation remained to continue giving the second dose of Vaxzevria between 4 and 12 weeks after the first, in line with the product information. There is no evidence that delaying the second dose influences the risk of TTS. Where the second dose of Vaxzevria is not given, no definitive recommendations on the use of a different vaccine for the second dose can be made at present (see EMA/ECDC Joint Statement).
AstraZeneca's COVID-19 vaccine, Vaxzevria, was granted approval in the European Union by the EMA as a third dose vaccine for adults on May 23, 2022. Healthcare professionals can now use Vaxzevria as a third dose booster in patients previously given a primary vaccine schedule of either Vaxzevria or an EU-approved mRNA COVID-19 vaccine.
Vaxzevria Side Effects
As of June 17, 2022, the EMA reported available evidence does not support a causal relationship between myocardial infarction, pulmonary embolism, and thrombosis with Vaxzevria. A total of 276,697 cases of suspected side effects were spontaneously reported from EU/EEA countries; 1,529 of these reported a fatal outcome, and about 69 million doses of Vaxzevria had been given to people in the EU/EEA. The EMA confirmed that the benefits of Vaxzevria continue to outweigh its risks. On February 1, 2022, the Annual of Internation Medicine published Original Research that concluded an exploratory retrospective cohort study among frontline personnel in Denmark that found the receipt of the AZD1222 vaccine was associated with a small excess risk for deep venous thrombosis.
Oxford University's Jenner Institute developed the Vaxzevria (AZD1222) vaccine, working with the Oxford Vaccine Group. AZD1222 was co-invented by the University of Oxford and Vaccitech. Vaccitech owns the rights to the viral vector technology ChAdOx, used in the Oxford vaccine, and was co-founded by Professor Sarah Gilbert, who has led the project.
On November 18, 2020, The Lancet published a study review that describes this vaccine's safety and immunogenicity in a broader range of participants, including adults aged 70 years and older. The vaccine candidate, ChAdOx1 nCoV-19, appears to be better tolerated in older adults than in younger adults and has similar immunogenicity across all age groups after a booster dose.
On December 30, 2020, the U.K.'s Medicines and Healthcare products Regulatory Agency provided authorization for an emergency supply of COVID-19 Vaccine AstraZeneca for the active immunization of individuals 18 years or older. On January 6, 2021, the Serum Institute of India obtained emergency use authorization in India for AstraZeneca's COVID-19 vaccine. And on January 12, 2021, the EMA received an application for conditional marketing authorization for COVID-19 Vaccine AstraZeneca. On January 29, 2021, the EMA recommended granting conditional marketing authorization for COVID-19 Vaccine AstraZeneca to prevent coronavirus disease 2019 (COVID-19) in 18 years of age.
AstraZeneca is a global, science-led biopharmaceutical company that focuses on discovering, developing, and commercializing prescription medicines, primarily for treating diseases in three therapy areas - Onc Cardiovascular, Renal & Metabolism, and Respiratory & Immunology.

Vaxzevria AstraZeneca COVID-19 Vaccine contains in one dose (0.5 ml) COVID-19 Vaccine (ChAdOx1-S recombinant) 5 × 10^10 viral particles (vp). ChAdOx1-S is a Recombinant, replication-deficient chimpanzee adenovirus vector encoding the SARS CoV 2 Spike (S) glycoprotein. Produced in genetically modified human embryonic kidney (HEK) 293 cells.
Produced in the genetically modified human embryonic kidney (HEK) 293 cells and by recombinant DNA technology. This product contains genetically modified organisms. Vaxzevria - AstraZeneca COVID-19 Vaccine (AZD1222) (C19VAZ) full ingredients can be found on this University of Oxford website. Vaxzevria is made up of another virus (adenovirus family) that has been modified to contain the gene for making a protein from SARS-CoV-2. The vaccine does not contain the SARS-CoV-2 coronavirus and cannot cause COVID-19.
Since authorization in 2021, AstraZeneca and its partners released two billion doses of their COVID-19 vaccine to more than 170 countries, such as Australia, Canada, and the U.K. Vaxzevria is estimated to have helped prevent 50 million COVID-19 cases, about five million hospitalizations, and saved more than one million lives worldwide. About 69 million doses of Vaxzevria in adults were administered in the EU/EEA from authorization to May 15, 2022.
India granted emergency approval for the vaccine co-developed by AstraZeneca Plc and the University of Oxford on January 1, 2021. Covishield is the Serum Institute of India version of the AstraZeneca COVID-19 vaccine.
The Vaxzevria - AstraZeneca (AZD1222) (ChAdOx1 nCoV-19) vaccine candidate is being tested to prevent infection of SARS-CoV-2, which causes COVID-19 disease.
While pregnancy puts women at higher risk of severe COVID-19, very little data are available to assess vaccine safety in pregnancy, wrote the WHO on September 2, 2021. Therefore, pregnant women may receive the vaccine if the benefit of vaccinating a pregnant woman outweighs the potential vaccine risks.
The peer-review journal The Lancet published on June 11, 2022, the findings from - Safety and immunogenicity of the ChAdOx1 nCoV-19 (AZD1222) vaccine in children aged 6–17 years: a preliminary report of COV006, a phase 2 single-blind, randomized, controlled trial - that concluded - 'ChAdOx1 nCoV-19 is well tolerated and immunogenic in children aged 6–17 years, inducing concentrations of antibody that are similar to those associated with high efficacy in phase 3 studies in adults. No safety concerns were raised in this trial.'
The Vaxzevria vaccine can be stored, transported, and handled under normal refrigerated conditions (2-8 degrees Celsius/ 36-46 degrees Fahrenheit) for at least 6 months and administered within existing healthcare settings.

July 7, 2021 - The NEJM published a study focused on three patients with vaccine-induced immune thrombotic thrombocytopenia after receiving the AstraZeneca vaccine who improved with therapeutic plasma exchange. Argatroban treatment was monitored closely before, during, and after the exchanges, and only minimal aPTT variation was found, with no attributable bleeding. Patients 1 and 2 recovered despite their severe presentation. Patient 1 received rituximab after the fifth therapeutic plasma exchange. The platelet count for Patient 2 did not improve until IVIG (0.5 g per kilogram of body weight) was given after therapeutic plasma exchanges 4 through 7. Patient 3 underwent above-knee amputation, but therapeutic plasma exchange most likely prevented more extensive resection. No further thromboses occurred. We suggest considering therapeutic plasma exchange for thrombocytopenia and thrombosis that does not begin to abate after 5 days, continuing until platelet normalization. Earlier intervention could be considered. The usefulness of additional treatment with IVIG, glucocorticoids, and rituximab requires further study.
