Inside BioNTech's quest to vaccinate the world_  by [Jamie Ducharme](https://time.com/author/jamie-ducharme/)  ## Jamie Ducharme Ducharme is a contributor to TIME. Jun 22, 2021 3:29 PM UTC Inside BioNTech's quest to vaccinate the world  by [Jamie Ducharme](https://time.com/author/jamie-ducharme/)  ## Jamie Ducharme Ducharme is a contributor to TIME. Jun 22, 2021 3:29 PM UTC On April 8, more than 4.3 million people in the U.S. received a COVID-19 vaccine dose. But after that peak, the numbers began to fall. By June 3, the national seven-day average for daily shots given had dropped to 850,000. But after that—with weeks to go before the Fourth of July, the date by which [President Joe Biden wanted](https://www.cnbc.com/2021/06/17/president-bidens-fourth-of-july-covid-vaccination-goals-are-in-jeopardy.html) 70% of U.S. adults to have gotten at least one shot—the numbers began to creep back up. On June 7, according to U.S. Centers for Disease Control and Prevention (CDC) [data](https://covid.cdc.gov/covid-data-tracker/#vaccination-trends), the seven-day average for daily vaccinations again broke a million. It shrank a bit after that, but was still close to 900,000 on June 15. While it’s common for daily numbers to go up and down, it’s somewhat surprising that this uptick would happen months after COVID-19 shots became widely available to U.S. adults. Vaccine supply now far outpaces demand. To keep shots going into arms, many states have done away with appointment requirements; opened mobile clinics and [partnered with community organizations](https://www.shvs.org/strategies-for-states-to-leverage-local-partnerships-for-equitable-distribution-of-covid-19-vaccinations/) in areas with low vaccine uptake; and dangled [incentives and cash prizes](https://time.com/6046238/covid-19-vaccine-incentives/) for those who get vaccinated. But Loren Lipworth-Elliot, the associate director of Vanderbilt University Medical Center’s epidemiology division, says there may be a partial explanation that has nothing to do with those efforts: In mid-May, kids ages 12 to 15 [became eligible](https://time.com/6047384/teens-pfizer-covid-vaccine/) to receive Pfizer-BioNTech’s shot. There are about 17 million U.S. adolescents in that age group, [according to](https://www.kff.org/policy-watch/covid-19-vaccines-for-12-15-year-olds-considerations-for-vaccine-roll-out/) the Kaiser Family Foundation. As of June 21, 28% of them had received at least one dose of a COVID-19 vaccine and almost 18% were fully vaccinated. That means almost 8 million shots have been given in that age group alone over the last six weeks. “That’s definitely accounting for some of what we’ve been seeing,” Lipworth-Elliot says. Dr. Mark Roberts, director of the Public Health Dynamics Lab at the University of Pittsburgh’s Graduate School of Public Health, agrees that childhood vaccinations are part of the explanation—but they’re probably not all of it, he says. “You’re seeing a fulfilling of that pent-up demand \[for pediatric immunizations\], but it’s not going to be huge,” he says, because 12- to 15-year-olds make up only about 5% of the U.S. population. It’s hard to say exactly what else has been driving the recent uptick, but Roberts says it may have something to do with recent state-run incentive programs, like lottery drawings for vaccinated people. Ohio, for example, [reported a 28% increase](https://odh.ohio.gov/wps/portal/gov/odh/media-center/odh-news-releases/odh-news-release-05-28-21) in vaccinations during the two weeks after it announced its Vax-a-Million lottery in May, compared to the week before the announcement. Trends vary widely from state to state, Lipworth-Elliot adds. States with relatively low vaccination rates, like Florida, Tennessee and Alabama, are among those seeing recent increases in vaccinations, while daily tallies are logically dropping off in areas where most eligible people are already protected. And while vaccination rates are still lower among Black and Hispanic/Latino people than among white people in the U.S., [federal data suggest](https://covid.cdc.gov/covid-data-tracker/#vaccination-demographics-trends) the gap is narrowing slightly, driven particularly by the Hispanic/Latino population. Both trends, Lipworth-Elliot says, suggest health officials are getting better at bringing vaccines to populations that need them and chipping away at vaccine hesitancy by building trust within communities. The fact that the CDC now says fully vaccinated people can safely [go mask-free](https://time.com/6048398/new-cdc-mask-guidance-indoors-outdoors/), socialize indoors and [travel](https://time.com/5952252/covid-19-vaccine-travel/) may also be encouraging some holdouts to get vaccinated, Lipworth-Elliot says. “People are seeing that there’s a lot of leeway and freedom given to people who are vaccinated, for good reason,” she says. [TIME/Harris Poll data](https://time.com/6051290/cdc-vaccine-mask/) also suggest the CDC’s mask guidance encouraged some people to get vaccinated because they were concerned about the risks of others going mask-free in public. It’s too soon to say if the positive momentum will continue; both Lipworth-Elliot and Roberts caution that variations in the vaccination data are common, and that it will take time to see how the trends play out. Already, daily averages are lower than they were a couple weeks ago. But there are reasons for optimism. Shots may become available to kids even younger than 12 [by the fall](https://www.mercurynews.com/2021/06/03/covid-children-ages-9-12-may-be-next-up-for-vaccine-and-when-according-to-fauci/), which would open up a whole new swath of the population to vaccination. And in a recent [Gallup poll](https://news.gallup.com/poll/350720/covid-vaccine-reluctant-likely-stay.aspx), about a fifth of adult respondents who said they do not plan to be vaccinated—a group equivalent to about 5% of the U.S. adult population—said they were open to changing their minds. With about 65% of U.S. adults already vaccinated with at least one dose, building trust even within that small group could be the difference between making or missing Biden’s Independence Day goal. ## Transcript [00:01] oh yes yes i'm vaccinated yes [00:06] Very cool [00:10] yes [00:11] yeah [00:12] yes, I did [00:13] it was very cool to to know [00:15] okay I'm gonna be vaccinated with a vaccine that I know really from day one [00:26] I mean who can tell that they're part of the solution for such a pandemic situation [00:30] I guess only a few people can say that and I'm really happy to be part of that [00:51] If you've been vaccinated for COVID-19, chances are that you are benefiting from the science [00:56] happening here at the German biotech company BioNtech. [01:00] In December 2020 BioNtech in partnership with Pfizer [01:04] were the first to earn authorization to distribute their vaccine to the public [01:17] In March 2021 TIME spent a week watching how BioNtech makes a batch [01:22] of 8 million doses of the COVID-19 vaccine at their new manufacturing plant in Marburg [01:29] they expect to produce 1 billion doses a year [01:44] the pace of production has been breakneck from the start [01:48] So in 2020 I think we worked [01:51] at every holiday, I can remember Easter Saturday I was standing here pipetting [01:55] samples to have the results as soon as possible [01:59] and now 24-hour shifts in this lab are producing [02:03] vaccines that will be shipped around the world [02:25] There are approximately 50, 000 steps at the lab [02:28] it begins with bags of pure mRNA the molecule that tells cells how to make the proteins that [02:33] launch the immune response and a buffer solution that starts the coding process [02:39] it emerges in bulk at the other end of the process as a liquid destined for vials [02:46] most of the machines are named after the engineers that developed the process [02:50] this one is named after Margaret the first patient in the clinical trials to receive the vaccine [02:56] but the beating heart of the lab is this machine a container that uses pressurized ethanol to encase [03:01] the mRNA and special lipid nanoparticles [03:05] those nanoparticles keep the mRNA protected until it [03:08] can jumpstart the immune response in the body's cells [03:38] Speed is essential but inside the lab everyone moves slowly and methodically [03:45] each of the 50,000 steps is logged by one technician confirmed by a second and only then does it actually happen [03:53] it's very important that the quality of the product and all the raw materials is perfect [04:00] here and so no impurities should be present in all raw materials and nothing which we don't [04:06] want to have in our products [04:08] one wrong move has the potential to damage the final product [04:12] if there's any accidental exposure let's say from an ill-timed sneeze [04:17] the entire batch must be thrown out, all eight million doses that's why everyone wears layers [04:23] of protection and they even disinfect their gloved hands repeatedly [04:45] in the lab where we were filming no one had ever told the technicians how many doses were in a batch [04:56] after that they sprayed another application of disinfectant onto their gloves just to be sure [05:13] based on our technology and on the antigen we were using no I wasn't [05:19] I'm very confident in the technology we have [05:22] until now vaccine development has been a slow process [05:26] the BioNtech vaccine uses a new technology based on mRNA it is revolutionizing the way [05:32] vaccines can be produced [06:03] When the COVID-19 pandemic broke out, BioNtech was primarily a cancer vaccine company [06:08] but by using this new mRNA technology it was able [06:11] to quickly pivot to a coronavirus vaccine [06:15] when you look back at any project you've ever done you've [06:17] always looked back at the start and go wow okay if I'd known that now i could have cut you know a few [06:24] hurdles out of my way earlier right but you're in a situation where you're doing something [06:29] especially for us as a smaller company that was unprecedented [06:32] the second part of the process happens at another factory [06:35] where vials are filled and packed into boxes for shipment [06:38] as the cycle comes to an end there's little time to celebrate after all another batch is waiting to be made ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6074717/covid-19-vaccination-trends/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6074717/covid-19-vaccination-trends/"},"headline":"After Weeks of Declining Vaccination Rates in the U.S., They Went Back Up in June.
