TIME followed the vaccination process from a Walgreens freezer to a long-term care facility to see what the roll out can look like._  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Mar 31, 2021 10:45 AM UTC TIME followed the vaccination process from a Walgreens freezer to a long-term care facility to see what the roll out can look like.  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Mar 31, 2021 10:45 AM UTC Pfizer-BioNTech says their COVID-19 vaccine is 100% efficacious in protecting adolescents aged 12 to 15 years from COVID-19 disease. On March 31, the companies released a statement summarizing the results of their study of the safety and efficacy of their vaccine, which is already [authorized](https://time.com/5920134/first-authorized-covid-19-vaccine-us/) in the U.S. and elsewhere for use in adults 16 years or older, in this younger age group. The results have been highly anticipated as state and local leaders—not to mention parents—are to keen send teens back to in-person school; this study suggests a path towards a return to pre-pandemic learning conditions, in which students won’t spread COVID-19 in the classroom. The trial involved 2,260 adolescents 12 to 15 years old, who were randomly assigned to get two doses of the COVID-19 vaccine or two doses of placebo. During the study, which began earlier this year, 18 teens developed COVID-19, all of them in the placebo group. The researchers found that the levels of virus-fighting antibodies generated by those getting the vaccine were considerably higher than levels among those receiving the placebo. “We share the urgency to expand use of our vaccine to additional populations and are encouraged by the clinical trial data from adolescents between the ages of 12 and 15,” Pfizer CEO Albert Bourla said in the statement. Based on the new data, the companies plan to ask the U.S. Food and Drug Administration (FDA) and the European Medicines Agency to expand emergency use authorization for the vaccine to include 12- to 15-year-olds. Even more encouraging the antibody levels exceeded the levels of those in the 16-25 year old age group in the original adult trial of the shots. And the researchers found no significant side effects from the vaccine among the teens, although they will continue to monitor them for long term efficacy of the shot as well as side effects for two years. Those data will ultimately help to enhance understanding of how COVID-19 affects children. So far, experts say children don’t seem to be affected by the virus as severely as older adults, although protecting them from symptoms of the disease is critical, not least as an additional way to curb spread of the virus. In a recent study of adults published by the U.S. Centers for Disease Control, scientists found that the mRNA-based vaccine not only protects against symptoms of the disease, but can ward off infection with the virus in the first place. The adolescent study wasn’t designed to confirm this in the younger population as well, but given younger people’s more responsive immune systems, it’s likely they might benefit from the same protection from infection. That would mean vaccinated students are far less likely to spread the virus in a school setting because they’re less likely to get infected to begin with. ## Transcript [00:08] But I am very excited [00:11] that you finally come up with a vaccine. [00:15] I feel the weight of it that this is going to do some good for us. [00:19] And you know that I'm ready for it to start happening. [00:24] You know, waiting to be in line to get my shot to. [00:34] Just all the way to the Yankees or. [00:37] Don't sign for Colbert. So they don't say. [00:40] I actually. [00:46] The biggest challenge [00:47] has been temperature requirements, because that has to be kept [00:52] at ultracold temperature of negative seven degrees Celsius. [00:57] Or if we are [00:57] transporting in a refrigeration, we have a lot more monitoring for that [01:01] because it's only good for so many hours if the temperature excursion happens. [01:07] And then there is a lot of responsibility in terms of liability. [01:10] This vaccine has been very popular, so we have security protocols. [01:14] We are putting SEALs when they're transporting. [01:18] We have cameras installed specifically for this [01:26] over and. [01:48] Yeah. [01:49] And be sorry. [01:52] All right. Keep your arm relaxed. [01:54] Oh, just the needle all done. [01:59] You're not even bleeding. [02:11] So my grandmother actually just passed away, [02:13] I mean, less than two months ago from it. [02:15] So to be out here protecting other people's [02:17] grandparents is really touching me personally. [02:18] Like, I really appreciate the opportunity and just so happy to be a part of it. [02:23] The staff members here, we have about 240 that we're doing. [02:27] We can get through usually with this many immunizations, 40 [02:31] or 50 an hour at this facility specifically, we have over 100 residents [02:35] that are all room to room based. [02:36] So that takes a little more time. [02:38] And then have you ever had a reaction after receiving a vaccine in the past? [02:44] I can see how grateful they are. [02:45] And I'm just grateful [02:47] and honored to be able to give them the vaccine [02:49] for me to be able to do it directly. [02:51] You know, the last patient I just did, she's like, I'm waiting for the vaccine. [02:54] And I was like, I'm here with the vaccine. [02:56] And she's like, You're here with the vaccine. [02:58] So I'm part of the bigger movement of vaccinating basically America. [03:04] And that's it. [03:06] Well, that's the easiest one I ever had. [03:09] I'm glad with hay fever, I was you know, [03:12] they can't come and visit me and I can't go visit them. [03:16] But it's. Oh, gosh, it makes me mad anyway. [03:20] It really is hard. [03:21] And it's been harder for a lot of other people who have lost folks. [03:26] And so I haven't had that problem, but [03:29] it's awful. [03:31] So I will mask myself [03:33] any time to prevent that from happening. [03:37] When I was a kid, [03:39] everybody knew people [03:43] who had somebody in their family that had polio. [03:47] Any vaccine that prevents [03:50] unnecessary pain and suffering is a good thing to have. [03:54] All right. [03:54] I'm just going to sanitize your arm real quick. [04:00] I am happy that my son sometimes [04:03] he talks to me on Facebook on face time. [04:08] This time. [04:09] And my daughter calls me every night. [04:12] I know I can touch them and see them, but [04:16] I just think the time will come. [04:18] I hope. I hope I'm still alive. [04:23] And make [04:25] sure you're safe. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/"},"headline":"Pfizer-BioNTech's COVID-19 Vaccine Works for Teens, According to a New Study","datePublished":"2021-03-31T10:45:38.000Z","dateModified":"2026-10-14T09:10:56.084Z","description":"The results should reassure parents and schools about reopening middle and high schools for vaccinated students","url":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/","keywords":["COVID-19"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4291e87c3acf8c08/698a1859929fad41b2bf7371/GettyImages-1230743606-e1617149100153.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4291e87c3acf8c08/698a1859929fad41b2bf7371/GettyImages-1230743606-e1617149100153.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"ISRAEL-HEALTH-VIRUS-VACCINE","caption":"ISRAEL-HEALTH-VIRUS-VACCINE","creditText":"AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/tag/covid-19/","name":"COVID-19"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/","name":"Pfizer-BioNTech's COVID-19 Vaccine Works for Teens, According to a New Study"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Tracking the Vaccine: From Freezer to Front Line","description":"TIME followed the vaccination process from a Walgreens freezer to a long-term care facility to see what the roll out can look like.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/0dwzz5K2/poster.jpg?width=720","uploadDate":"2021-01-20T18:06:16.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/0dwzz5K2.m3u8","embedUrl":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/","duration":"PT4M28S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/5951361/pfizer-biontech-covid-19-vaccine-teens/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
