Vaxzevria COVID-19 Vaccine AstraZeneca Description

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). Genetic material has been added to the ChAdOx1 construct, which is used to make proteins from the SARS-CoV-2 coronavirus called Spike glycoprotein (S). The vaccine does not contain the virus itself and cannot cause COVID-19, says the European Medicines Agency (EMA).

This protein is usually found on the surface of SARS-CoV-2 and plays an essential role in the infection pathway of the SARS-CoV-2 virus. The SARS-CoV-2 coronavirus 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. Vaxzevria is made up of another virus (of the adenovirus family) that has been modified to contain the gene for making a protein from SARS-CoV-2.

Vaxzevria is a vaccine for preventing COVID-19 in people aged 18 years and older, says the ECDC

The WHO published on February 10, 2021, background evidence related to the Interim recommendations for using the AZD1222 (ChAdOx1-S [recombinant]) vaccine against COVID-19 developed by Oxford University and AstraZeneca. The EMA authorized Vaxzevria in February 2021. On March 26, 2021, the EMA posted 'Vaxzevria' as the new name for COVID-19 Vaccine AstraZeneca.

AstraZeneca's Vaxzevria - AZD1222 (ChAdOx1 nCov-19) (C19VAZ) vaccine's Accession Number: DB15656. The UNII Preferred Substance Name: B5S3K2V0G8.

Vaxzevria COVID-19 Vaccine AstraZeneca History

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.

A preliminary report of the COV001/2 phase 1/2 study published on July 20, 2020, showed a single dose of AZD1222 resulting in a 4-fold increase in antibodies to the SARS-CoV-2 virus spike protein 95% of participants one month after injection. The AZD1222 vaccine candidate has progressed into late-stage Phase II/III clinical trials in various countries. 

On November 18, 2020, The Lancet published a study review that describes this vaccine's safety and immunogenicity in a wider 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.

The Lancet issued a press release on December 8, 2020, announcing 'the first full results from interim analysis confirm that the Oxford COVID-19 vaccine (AZD1222) has an acceptable safety profile and is efficacious against symptomatic COVID-19 disease, with no hospitalizations or severe disease reported in the COVID-19 vaccine group so far.

On December 17, 2020, Professor Katie Ewer, a lead author of a recent paper, said: ‘This highly detailed analysis of the immune responses to ChAdOx1 nCoV-19 further underpins the potential of this vaccine to induce protection against COVID-19 disease and provides additional reassurance of the safety of this approach. Using these advanced immunological techniques, we can better understand the different cellular and antibody-mediated mechanisms that contribute to the protection afforded by this vaccine, as demonstrated in the recent data from the subsequent Phase 3 trials’. 

On December 30, 2020, the UK'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 of 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. 

The primary analysis of Phase III clinical trials from the UK, Brazil, and South Africa, published as a preprint in The Lancet on February 1, 2021, confirmed COVID-19 Vaccine AstraZeneca is safe and effective at preventing COVID-19, with no severe cases and no hospitalizations, more than 22 days after the first dose.

On March 22, 2021, Ann Falsey, Professor of Medicine, University of Rochester School of Medicine, US, and co-lead Principal Investigator for the US Phase III trial, called D8110C00001, stated in a press release, “These findings reconfirm previous results observed in AZD1222 trials across all adult populations but it’s exciting to see similar efficacy results in people over 65 for the first time. This analysis validates the AstraZeneca COVID-19 vaccine as a much-needed additional vaccination option, offering confidence that adults of all ages can benefit from protection against the virus.”

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. Based in Cambridge, UK, AstraZeneca operates in over 100 countries.

Vaxzevria COVID-19 Vaccine AstraZeneca Side Effects

On March 18, 2021, the EMA’s safety committee, PRAC, concluded its preliminary review of a signal of blood clots in people vaccinated with COVID-19 Vaccine AstraZeneca at its extraordinary meeting. The Committee confirmed that: the benefits of the vaccine in combating the still widespread threat of COVID-19 (which itself results in clotting problems and could be fatal) continue to outweigh the risk of side effects; the vaccine is not associated with an increase in the overall risk of blood clots (thromboembolic events) in those who receive it; there is no evidence of a problem related to specific batches of the vaccine or particular manufacturing sites; however, the vaccine may be associated with very rare cases of blood clots associated with thrombocytopenia, i.e., low levels of blood platelets (elements in the blood that help it to clot) with or without bleeding, including rare cases of clots in the vessels draining blood from the brain.

On March 24, 2021, AstraZeneca AB, in agreement with the European Medicines Agency, confirmed the 'COVID-19 Vaccine AstraZeneca: benefits outweigh the risks despite possible link to very rare blood clots with low blood platelets. In some cases, a combination of thrombosis and thrombocytopenia, accompanied by bleeding, has been observed very rarely following vaccination with COVID-19 Vaccine AstraZeneca. And healthcare professionals should be alert to the signs and symptoms of thromboembolism and or thrombocytopenia, stated the EMA.

The EMA announced on April 7, 2021, the EMA’s safety committee had concluded today that unusual blood clots with low blood platelets should be listed as very rare side effects of Vaxzevria (formerly COVID-19 Vaccine AstraZeneca). Based on the currently available evidence, specific risk factors have not been confirmed. In reaching its conclusion, the EMA committee considered all currently available evidence, including the advice from an ad hoc expert group.

UK and EU regulators requested their vaccine labels be updated to warn of these “extremely rare potential side effect(s).” The data suggest a slightly higher incidence reported in the younger adult age groups.

On May 5, 2021, the BMJ published a study: Arterial events, venous thromboembolism, thrombocytopenia, and bleeding after vaccination with Oxford-AstraZeneca ChAdOx1-S Denmark and Norway: population-based cohort study. Conclusions -  Among recipients of ChAdOx1-S, increased rates of venous thromboembolic events, including cerebral venous thrombosis, were observed. For the remaining safety outcomes, results were largely reassuring, with slightly higher rates of thrombocytopenia/coagulation disorders and bleeding, which could be influenced by increased surveillance of vaccine recipients. However, the absolute risks of venous thromboembolic events were small, and the findings should be interpreted in light of the proven beneficial effects of the vaccine, the context of the given country, and the limitations to the generalisability of the study findings.

As of June 2, 2021, the United Kingdom Medicines & Healthcare Regulatory Agency had received 836 Yellow Card reports for the COVID-19 Vaccine AstraZeneca (Vaxzevria), in which the patient died shortly after vaccination.

On June 7, 2021, the EMA’s COVID-19 task force (COVID-ETF) began advising healthcare professionals in the EU to consider recommendations by learned societies when assessing people with signs and symptoms of thrombosis thrombocytopenia syndrome (TTS) following vaccination with Vaxzevria. TTS requires rapid identification and urgent clinical management. National and international recommendations have been updated with evolving experience from managing TTS and heparin-induced thrombocytopenia and thrombosis, a condition with some similarities to TTS.

The EMA’s safety committee concluded on June 11, 2021, that women who have previously had capillary leak syndrome must not be vaccinated with Vaxzevria (formerly COVID-19 Vaccine AstraZeneca). The committee also concluded that capillary leak syndrome should be added to the product information as a new side effect of the vaccine, together with a warning to raise awareness among healthcare professionals and patients of this risk.

Vaxzevria COVID-19 Vaccine AstraZeneca Ingredients

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 at 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 itself and cannot cause COVID-19.

Vaxzevria COVID-19 Vaccine AstraZeneca Distribution

AstraZeneca continues to engage with governments, multilateral organizations, and collaborators worldwide to ensure broad and equitable access to the vaccine at no profit for the pandemic duration. The Company is making rapid progress in manufacturing with a capacity of up to 3 billion doses of the vaccine in 2021 on a rolling basis, pending regulatory approval. 

On March 2, 2021, AstraZeneca announced it would supply 142 countries as part of the unprecedented effort with COVAX to bring broad and equitable access to the vaccine. The PAHO Revolving Fund, responsible for procuring vaccines against COVID-19 for the countries in the Americas, via the COVAX Mechanism, was sent to Brazil on March 21, 2021, the 1,022,400 doses of the AstraZeneca/Oxford vaccine manufactured by SK Bioscience from South Korea.

CoviShield Vaccine

India granted emergency approval for the coronavirus 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.

Sputnik V Vaccine Co-Development

The Russian Direct Investment Fund announced on February 9, 2021, that the Ministry of Health of the Republic of Azerbaijan had issued a permit to conduct local clinical trials of a combined COVID-19 vaccine candidate, which includes the Sputnik V vaccine and one co-developed by AstraZeneca and Oxford University.

Vaxzevria COVID-19 Vaccine AstraZeneca Indication

The Vaxzevria - AstraZeneca (AZD1222) (ChAdOx1 nCoV-19) vaccine candidate is being tested to prevent infection of SARS-CoV-2, which causes COVID-19 disease.

On May 7, 2021, the UK's Joint Committee on Vaccination and Immunisation advised a preference for people aged 30 to 39 without underlying health conditions to receive an alternative to the Oxford/AstraZeneca vaccine.

Vaxzevria COVID-19 Vaccine AstraZeneca Dosing

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. This dosing regimen was shown in clinical trials to be well-tolerated and effective in preventing symptomatic COVID-19, with no severe cases and no hospitalizations more than 14 days after the second dose.

A non-peer-reviewed study published on April 13, 2021, found a single dose of the AZD1222/Covishield vaccine was shown to be highly immunogenic in previously naïve individuals inducing antibody levels greater than following natural infection.

On June 4, 2021, Ireland's Health Minister Stephen Donnelly confirmed that the interval between the two doses would be reduced by a third (12 weeks to eight) following advice from the National Immunisation Advisory Committee (NIAC).

Vaxzevria COVID-19 Vaccine AstraZeneca Storage Requirements

The Vaxzevria vaccine can be stored, transported, and handled at normal refrigerated conditions (2-8 degrees Celsius/ 36-46 degrees Fahrenheit) for at least 6-months and administered within existing healthcare settings.

Vaxzevria COVID-19 Vaccine AstraZeneca CPT Code

March 16, 2021 - EMA’s safety committee (PRAC) announced in a digital statement 'it made further progress today, Tuesday 16 March, in its detailed evaluation of cases of blood clots, some with unusual features such as low numbers of platelets, in recipients of COVID-19 Vaccine AstraZeneca. As previously stated, while its investigation is ongoing, EMA currently remains of the view that the benefits of the AstraZeneca vaccine in preventing COVID-19, with its associated risk of hospitalization and death, outweigh the risks of side effects.'

March 15, 2021 - The EMA issued a statement: Several authorities responsible for national vaccine campaigns in EU countries have temporarily paused vaccination with COVID-19 Vaccine AstraZeneca. Events involving blood clots, some with unusual features such as low numbers of platelets, have occurred in a very small number of people who received the vaccine.

March 14, 2021 - The Company issued a press statement which stated: 'A careful review of all available safety data of more than 17 million people vaccinated in the European Union (EU) and the UK with COVID-19 Vaccine AstraZeneca has shown no evidence of an increased risk of pulmonary embolism, deep vein thrombosis (DVT) or thrombocytopenia, in any defined age group, gender, batch or in any particular country. So far across the  EU and UK, there have been 15 events of DVT and 22 events of pulmonary embolism reported among those given the vaccine, based on the number of cases the Company has received as of 8 March. This is much lower than expected to occur naturally in a general population of this size and is similar across other licensed COVID-19 vaccines. The monthly safety report will be made public on the European Medicines Agency website in the following week, in line with exceptional transparency measures for COVID-19.'

March 12, 2021 - The International Society on Thrombosis and Haemostasis recommends that all eligible adults continue to receive their COVID-19 vaccinations, despite the recent decisions by Austria, Denmark, Norway, and Iceland to at least temporarily suspend the use of the AstraZeneca vaccine due to reports of thrombosis.

March 12, 2021 - The European Medicines Agency stated it is reviewing all cases of thromboembolic events and other conditions related to blood clots, reported post-vaccination with COVID-19 Vaccine AstraZeneca.

March 11, 2021 - The UK's Medicines and Healthcare products Regulatory Agency stated in a website statement regarding actions to temporarily suspend the AstraZeneca COVID-19 Vaccine: 'This is a precautionary measure by the Danish, Norwegian and Icelandic authorities. It has not been confirmed that the AstraZeneca COVID-19 Vaccine caused the report of a blood clot. People should still go and get their COVID-19 vaccine when asked to do so.'

March 11, 2021 - Various media sources reported that countries in Austria, Denmark, Iceland, Norway, Estonia, Lithuania, Luxembourg, Italy, and Latvia have temporarily suspended vaccination programs.

March 10, 2021 - The EMA reported Austrian's national competent authority had suspended using a batch of COVID-19 Vaccine AstraZeneca (batch number ABV5300) after a person was diagnosed with multiple thrombosis (formation of blood clots within blood vessels) and died 10 days after vaccination. Another was hospitalized with pulmonary embolism (blockage in arteries in the lungs) after being vaccinated. The latter is now recovering.

March 6, 2021 - The Lancet published a commentary: Single-dose Oxford–AstraZeneca COVID-19 vaccine followed by a 12-week booster. Overall, the value of this study is in providing evidence that a single dose of the ChAdOx1 nCoV-19 vaccine is highly efficacious in the 90 days after vaccination, that a longer prime-boost interval results in higher vaccine efficacy, and that protection against symptomatic COVID-19 is maintained despite a longer dosing interval. It offers much-needed evidence for the UK policy of extending the dosing interval to 12 weeks and rapid mass immunization campaigns worldwide.

March 4, 2021 - Germany’s independent vaccine committee has formally approved the AstraZeneca vaccine for people age 65 and over, the health minister Jens Spahn told local media.

February 19, 2021 - The Lancet published a study that concluded: The results of this primary analysis of two doses of ChAdOx1 nCoV-19 were consistent with those seen in the trials' interim analysis confirm that the vaccine is efficacious, with results varying by dose interval in exploratory analyses. A 3-month dose interval might have advantages over a program with a short dose interval for the roll-out of a pandemic vaccine to protect the largest number of individuals in the population as early as possible when supplies are scarce while also improving protection after receiving a second dose.

February 18, 2021 - The European Medicines Agency(EMA) published its overview of the COVID-19 Vaccine AstraZeneca, approved in the EU. The EMU also published its Product Information sheet.
