![]() thus far have been ones produced by the company’s regulated facility in the Netherlands. The only J&J COVID shots administered in the U.S. To be clear, no affected doses were apparently shipped from the facility, and the problem was detected during routine quality control checks, as it should have been. Johnson & Johnson said that it was “assuming full responsibility” for production at the Baltimore plant, and “adding dedicated leaders for operations and quality, and significantly increasing the number of manufacturing, quality and technical operations personnel to work with the company specialists already at Emergent.” It will also reportedly bring in personnel from Merck, which J&J has contracted with to produce its vaccine, as well.Īn Emergent spokesperson told the Washington Post that the company was “welcoming additional Johnson & Johnson personnel on-site at for their technical expertise and support.” The Times adds that, “Experts in vaccine manufacturing said that in the past, the had a rule to prevent such mishaps by not allowing a facility to make two live viral vector vaccines, because of the potential for mix-ups and contamination.” It’s not clear when or why that rule was abandoned, either in this specific case, or overall. by the Food and Drug Administration, will be moved elsewhere it’s not yet clear if Emergent will be left in charge of that operation. The production of the AstraZeneca vaccine, which still hasn’t been authorized for use in the U.S. Moving forward, per HHS, the plant will only produce the J&J vaccine. The contract manufacturer, Emergent, had been making both the J&J and AstraZeneca vaccines at the facility, and ruined one batch of the J&J vaccine last month after it mixed up the ingredients from the two. The New York Times reported Saturday that the Department of Health and Human Services, in an “extraordinary move,” has directed J&J to bring in a new leadership team and take over all aspects of manufacturing the vaccine at the Baltimore plant. The CDC says that by taking steps like wearing masks, physical distancing, and avoiding crowed spaces - while at the same time working to get everyone fully vaccinated - we will save lives and be able to return to normal life much more quickly.Emergent BioSolutions plant in Baltimore, Maryland.ĭays after Johnson & Johnson announced that it had to throw out 15 million doses of its increasingly popular one-shot coronavirus vaccine due to a screw-up at a plant run by manufacturing partner Emergent BioSolutions, the Biden administration has stepped in and put Johnson & Johnson in charge of vaccine production at the plant. The Centers for Disease Control and Prevention (CDC) has lauded the arrival of the Johnson & Johnson vaccine, stating that it is an important tool to vaccinate “as many people as possible, as quickly as possible.” While there’s a difference in effectiveness between the Johnson & Johnson vaccine and those from Pfizer-BioNTech and Moderna, all vaccines are effective against COVID-19, according to Banerji. ![]() While Catholic Church leaders favor taking the Pfizer-BioNTech and Moderna vaccines if possible, public health officials say it’s important to take whichever vaccine becomes available to you first.Ī fully vaccinated population is the quickest way to achieve control of the pandemic. Why is it important to take whichever vaccine becomes available first? In fact, many people are already taking medications we wouldn’t have today without the use of this technology. They’ve been used in a wide range of medical therapies for decades. The use of cell lines in this manner isn’t new. The Pfizer-BioNTech and Moderna vaccines do not use a viral carrier. ![]() It uses a fetal cell line in its manufacture because it uses a modified adenovirus as the carrier for the SARS-CoV-2 spike protein gene. PER.C6 is a retinal cell line that was isolated from a fetus in 1985. It required the use of a cell line called PER.C6 in both its development and manufacture. The Johnson & Johnson vaccine, however, has made more extensive use of fetal cell lines. ![]() It’s unknown whether it originated from a spontaneous abortion (miscarriage) or an elective abortion. HEK-293 is a kidney cell line that was isolated from a fetus in 1973. “However, both of these companies used the fetal cell line HEK-293 in the confirmation phase to ensure the vaccines work,” she said. “Neither the Pfizer nor Moderna vaccines used fetal cell lines during the development or production phases, so there are no fetal cells in the vaccine,” Banerji said. Viruses that can infect humans grow best in human cells. How are they involved in the production of COVID-19 vaccines?įetal cells lines are used in vaccine research because viruses need cells in which to grow.
