Inside BioNTech’s Manufacturing unit The place Pfizer Vaccine Is Made


If you’ve been vaccinated for COVID-19, chances are high fairly excessive that you simply’re benefiting from a product made by BioNTech. The German biotech firm, co-founded by a husband-and-wife workforce of scientists, developed the vaccine that grew to become not solely the primary to earn authorization within the U.S. for COVID-19 in December but in addition the primary ever based mostly on a brand new expertise involving the genetic materials mRNA.

In interviews in December and March, co-founders Ugur Sahin and Ozlem Tureci spoke about their whirlwind yr and their partnership with U.S. pharmaceutical firm Pfizer to check and manufacture the vaccine. Over three days in late March, in addition they opened up their new manufacturing plant to TIME for the primary step-by-step take a look at how their lifesaving, and probably pandemic-ending, vaccine is made.

The brand new BioNTech manufacturing facility is in a wooded valley in Marburg. Technicians working in one of many prep labs usually spot deer roaming within the close by forest.

As Quality Control Lab Manager, Witali Schmidt oversees the testing of all raw materials coming in, as well as the finished product going out.  The product produced here goes into the human body,  he says.  So it's very important that the quality is perfect, that the person only gets the vaccine and nothing besides that.

When Sahin learn a scientific paper in late January 2020 describing the primary recognized instances of COVID-19 in Wuhan, China, “it was very clear to me that this was not a neighborhood outbreak anymore,” he says. “And almost definitely the virus had already unfold worldwide.”

He knew there was no time to waste. However BioNTech, based mostly in Mainz, was then primarily a cancer-vaccine firm; after greater than a decade of analysis and improvement, the corporate had examined its mRNA-based most cancers vaccines in about 400 individuals, with encouraging outcomes. They had been simply exploring the opportunity of creating vaccines towards infectious illnesses–particularly an mRNA-based vaccine towards flu–when COVID-19 hit.

To keep it protected in the body, the mRNA is encased in a bubble of lipids through a process that uses pure, pressurized ethanol. Because ethanol is highly explosive, technicians must wear special static-free boots.

“[Ugur] satisfied all of us, together with our board, colleagues and scientific groups, that this was now our calling and we’ve got to comply with this mission,” says Tureci. At an emergency assembly, Sahin urged a 40-member workforce to “transfer with the pace of sunshine” towards the corporate’s new purpose of creating a COVID-19 vaccine. The workforce, which grew to greater than 200, labored nights and thru holidays on Challenge Lightspeed, and after a number of weeks had produced 20 candidates. An unprecedented 4 confirmed promise in neutralizing the virus. “There was a transparent message that this needs to be the precedence,” says Andreas Kuhn, senior vice chairman of RNA biochemistry and manufacturing at BioNTech. “No matter you’re doing proper now, type of neglect about it as a result of that is an important factor now.”

With so little identified in regards to the new virus, the workforce turned to what was identified about two associated coronaviruses: SARS and MERS. Quickly it had a 50,000-step course of for constructing an mRNA vaccine towards the brand new coronavirus, SARS-CoV-2.

Before pivoting to the COVID-19 vaccine, BioNTech was largely focused on using the new mRNA technology to develop cancer vaccines.  What the success of the coronavirus vaccine has now shown is that mRNA is really a proven technology for infectious diseases,  says Andreas Kuhn, senior vice president of RNA biochemistry and manufacturing at BioNTech.  We haven't forgotten about the cancer patients—the cancer programs are still running as much as it's possible under the current circumstances. We will of course go back.  Kuhn was recently vaccinated.  It was the first time that I got a vaccine, or any kind of medication, where I was actually involved in making it,  he adds.  So that was really special.

Earlier than pivoting to the COVID-19 vaccine, BioNTech was largely centered on utilizing the brand new mRNA expertise to develop most cancers vaccines. “What the success of the coronavirus vaccine has now proven is that mRNA can be a confirmed expertise for infectious illnesses,” says Andreas Kuhn, senior vice chairman of RNA biochemistry and manufacturing at BioNTech. “We’ve not forgotten in regards to the most cancers sufferers—the most cancers packages are nonetheless working as a lot because it’s attainable underneath the present circumstances. We are going to after all return.” Kuhn was lately vaccinated. “It was the primary time that I received a vaccine, or any type of treatment, the place I used to be really concerned in making it,” he provides. “In order that was actually particular.”

It begins in a 50-L stainless-steel tank that extra carefully resembles a beer keg than what you may think to be a part of a lifesaving bioreactor. Inside are fragments of mRNA coding for the SARS-CoV-2 spike protein, the Achilles’ heel of the virus that the vaccine will exploit. Your entire manufacturing course of occurs in a hermetically sealed system, with merchandise from every stage transported to the subsequent by way of a community of clear plastic tubing.

Even so, simply to be protected, technicians routinely check the air within the manufacturing rooms for any extraneous micro organism or pathogens, and people working with the vaccine recurrently faucet every gloved finger onto petri dishes stuffed with agar that may tradition for any stray microbes which may have made their method into the ability.

From start to finish, the entire manufacturing process flows through hermetically sealed plastic tubing. After the vaccine is pumped into bulk packaging, the tubes are sealed, then cut, to finish the process.

As a result of mRNA is comparatively unstable, it wouldn’t survive in its uncooked type within the human physique. With the intention to hold the mRNA protected, it’s encased in a fatty bubble utilizing pressurized ethanol–a extremely flammable substance. The method occurs in considered one of six 50-L tanks, every in its personal sealed-off room. The few individuals approved to enterprise out and in of the rooms placed on particular static-free sneakers to keep away from producing an unintended friction spark that might set off an explosion. 5 of the tanks are named for workforce members who had been instrumental in creating the method, and the sixth is known as Margaret, after the U.Okay. grandmother who was the primary individual to obtain the vaccine.

As soon as the ethanol has carried out its job of making the mRNA-containing bubbles, it’s filtered out. The result’s then filtered a number of instances extra, finally ending up as a milky resolution that fills 10-L plastic luggage. That liquid is shunted to the so-called fill-and-finish section, the place it’s purified in tanks after which squirted into sterile vials–every containing as much as six doses–which might be shipped to clinics around the globe.

BioNTech presently produces 8 million doses of its vaccine each three to seven days on the new Marburg facility that the corporate bought from Novartis final fall. (Many lab technicians, most of whom transferred to BioNTech, nonetheless put on their previous lab coats with the Novartis brand, as there hasn’t been time to order new ones.) In the end, the plant will churn out 1 billion doses a yr, and BioNTech is working with Pfizer, which oversaw the ultimate human testing that resulted within the vaccine’s authorization within the U.Okay., the U.S. and elsewhere, to ramp up manufacturing to provide the two.5 billion doses it dedicated to offering the world in 2021.

Each firms are fast to level out that their work shouldn’t be carried out. Sahin and his workforce are additionally maintaining a tally of new variants of the virus beginning to take maintain around the globe, and have already developed one other vaccine to focus on these viral variations, and so they plan to begin testing it quickly.

Once bottled, the Pfizer-BioNTech vaccine is stored at -82°C (-116°F) at a filling and labeling facility in Halle.

With the success of the COVID-19 mRNA vaccine, Sahin and Tureci see mRNA expertise as enjoying a extra dominant position in treating different illnesses as nicely, and are getting ready to select up the work on flu and most cancers vaccines that was interrupted by the pandemic. For now, the workforce is rightfully happy with what it’s completed in a really busy yr.

“It is a once-in-a-lifetime challenge,” says Alexander Muik, director of immunomodulators on the firm, who was concerned within the early phases of creating the vaccine. “Who can say that they’re a part of the answer for a pandemic? Just a few individuals can say that.”
