The lack of demand for the vaccination, which at first gave rise to hopes that it would be crucial in defending the world against the virus, forced AstraZeneca Plc to remove its Covid-19 vaccine from the market. According to a statement from Astra, the company requested that the marketing license for the vaccine, Vaxzevria, be removed this week because it is no longer produced or provided. It stated that safety considerations had no bearing on the decision.
Developed in collaboration with Oxford University, Astra’s vaccine was first made available on a non-profit basis. The vaccine was hailed as a success for Britain, with then-Prime Minister Boris Johnson becoming the first person to publicly get a dosage. Concerns related to its safety and effectiveness dogged the deployment, though, beginning with French President Emmanuel Macron’s description of it as “quasi-ineffective” on older adults not long after it was given EU approval.
The vaccine was considered a good option to inoculate a broad percentage of the world because it didn’t require ultra-cold storage like some of the competing Covid-19 doses did. Over 3 billion dosages were provided.
A greater setback followed Macron’s remarks when authorities started looking into the vaccine’s possible connection to extremely uncommon incidents of abnormal blood clots. In the end, regulators concluded that the vaccine’s risk-benefit ratio was favorable.
As nations sought to obtain booster shots for its populace, mRNA-based vaccines—particularly one created by a collaboration between BioNTech SE and Pfizer Inc.—were chosen over Astra’s vaccine. The relatives of patients who passed away after getting the vaccine are suing Astra.
Since then, businesses like Pfizer and Moderna Inc. have created improved Covid-19 vaccinations that target more recent variations. According to Astra, this has caused “a surplus of available updated vaccines” and a drop in the number of people requesting the shot.
