A batch of doses of the Johnson & Johnson vaccine against Covid-19 produced at a plant in Baltimore, USA, “did not meet quality standards” and cannot be used, the drug giant said on Wednesday ( 31).
The American company has not confirmed the number of vaccines affected. The revelation was made by the newspaper “The New York Times”, which speaks of up to 15 million “destroyed” doses.
According to the newspaper, a subcontractor mixed Johnson & Johnson and Oxofrd / AstraZeneca vaccine ingredients, delaying shipments of new doses. Federal officials have blamed the failure on human error.
Johnson & Johnson says the batch produced at an Emergent BioSolutions factory in Baltimore, Maryland, “has not advanced to the final stages of the manufacturing process.” “Quality and safety remain our top priorities”.
The company also said that is sending more experts to the site to “supervise, direct and support all vaccine production” and promises to deliver another 24 million doses in April.
According to the Associated Press news agency, Emergent BioSolutions is one of about ten companies that Johnson & Johnson is subcontracting to speed up the manufacture of its vaccine.
The New York Times says the error does not affect the Johnson & Johnson doses being delivered and used across the country, including next week’s shipments, as they were produced in the Netherlands.
What vaccine is this? Janssen (Johnson & Johnson)
The Johnson & Johnson vaccine does not need to be stored at very low temperatures and is the only vaccine already approved that is applied in a single dose in the world. It was tested in Brazil and can be kept between 2ºC and 8ºC for up to three months.
The Brazilian government bought 38 million doses of the vaccine, but deliveries are expected to be made only in July (16.9 million in the third quarter and 21.1 million in the fourth).
