Some people may get a new flu shot that’s made with dog cells instead of chicken eggs_ by [Alexandra Sifferlin](https://time.com/author/alexandra-sifferlin/) ## Alexandra Sifferlin Nov 17, 2014 7:05 PM UTC  645 squadron 645 squadron Getty Images by [Alexandra Sifferlin](https://time.com/author/alexandra-sifferlin/) ## Alexandra Sifferlin Nov 17, 2014 7:05 PM UTC Bird flu strain H5N8 has been[ identified](http://uk.reuters.com/article/2014/11/17/uk-health-birdflu-idUKKCN0J11N120141117) on a duck farm in England and in chickens at a farm in the Netherlands. Should people be scared about a new pandemic? Experts say, no. **Where are the latest cases?** On November 17, bird flu was confirmed on a duck farm in East Yorkshire. About 6,000 ducks will be killed and a 6-mile surveillance zone is going up around the farm. The emergence comes just a day after bird flu was detected in the Netherlands at an egg farm. [According to the BBC](http://www.bbc.com/news/uk-30076961), the Dutch government has imposed a three-day ban on poultry and eggs transport. Officials are currently figuring out whether the two cases are connected. Earlier this month, bird flu [also appeared in Germany.](https://www.gov.uk/government/news/avian-flu-outbreak-in-duck-breeding-farm-in-yorkshire) **Should I be afraid?** Not right now. First, it should be noted that there are several strains of bird flu, or avian influenza, and the recent strains have only so far emerged in birds, not humans. The Dutch and German governments [determined](http://uk.reuters.com/article/2014/11/17/uk-health-birdflu-idUKKCN0J11N120141117) their strains of the flu are both H5N8, a highly contagious virus that has never been found in humans. The British government has not yet said what strain of bird flu is circulating in the duck farm, but they have confirmed that it’s not H5N1, which can infect humans. **So what’s the big deal?** Farms with H5N8 outbreaks can face serious economic losses. **So it hasn’t affected humans before. Does that mean it won’t—ever?** Experts cannot completely rule out the possibility of human infection. “This particular strain has not been known to infect humans but, based on experience with H5N1, we know that H5 viruses have that capacity,” says Dr. Amesh Adalja, a senior associate of the University of Pittsburgh Medical Center Center for Health Security. “Thus far, avian influenza viruses have very limited human-to-human transmission capacity, so the general public need not panic, however poultry handlers may be at risk for infection. It will be important to understand the dynamics of this outbreak and understand the potential of H5N8 to infect humans.” **What about H5N1 makes it so much more worrying?** H5N1 is the strain that can spread to humans from birds, and it’s infected more than 600 people from 15 countries since November 2003, [the Centers for Disease Control and Prevention (CDC) reports](http://www.cdc.gov/flu/avianflu/h5n1-people.htm). About 60% of people who have contracted the strain have died. The majority of human cases are among people with direct or close contact with sick or dead infected poultry, and the disease does not efficiently transmit from person to person. However, if that were to change, scientists say we’d have a serious problem on our hands. **Is there a treatments or vaccine for bird flu?** Not exactly. In Nov. 2013, the FDA [approved](http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm376444.htm?source=govdelivery&utm%5Fmedium=email&utm%5Fsource=govdelivery) a H5N1 vaccine intended for the National Stockpile and not for commercial use_._ The CDC [has told TIME](http://time.com/3184/h7n9-bird-flu-china-pandemic-influenza/) that the vaccine is not very effective and would likely require more than one dose. Researchers are working on other vaccines for bird flu and its various strains, though none are currently approved. Right now, preventing the spread of infection is the best bet for keeping cases low. “Avian influenza will always be a major infectious disease threat. Certain avian influenza viruses—such as H5N1 and H7N9—have very high case fatality rates and are leading contenders for wider spread amongst the human population,” says Adalja. And while the current cases of bird flu shouldn’t freak you out, it is important for the global community to pay attention to the various strains and support vaccine and drug development. ## Transcript [ MUSIC ] This year, your annual flu shot might be more high tech than the ones you've had before. For decades, flu shots could only be made with the help of hundreds of thousands of chicken eggs. Scientists grew the influenza virus in the chicken eggs. Then purified and modified it to go into the flu vaccine. But that process took months for the virus to grow. In 2012 the U. S. Food and Drug Administration approved an entirely new way of making flu vaccines. Bypassing chicken eggs altogether and using animal cells instead. The Novartis Plant in Holly Springs, North Carolina is the only facility in the U. S.. Approved to produce a cell culture- based flu vaccine known as Flucelvax. This Influenza vaccine is grown using cells from dog kidneys. And the process is much faster. Taking 65 to 75 hours. Compared to the months it took to grow with [ UNKNOWN ] [ MUSIC ] The process begins with growing enough kidney cells to serve as the viruses incubators. Over 20 days the cells are put into a culture that encourages them to divide rapidly. And as the cells grow in number they are moved into increasingly larger vats. They start out in 5 liter. Containers and end up in a 5000 liter tank. Once there, the cells are infected with the flu virus. These samples of virus arrive frozen and are chosen each year by the World Health Organization in the spring. They determine which flu strains they believe will be circulating later that year. Year. After the cells produce enough virus, the viral particles are strained out, purified, and treated so they can't actually cause flu but can still alert the immune system to mount a response against the virus. This year, the facility produced 30 million doses [ INAUDIBLE ] Including its first full batch of the vaccine. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3589257/bird-flu-h5n8-europe/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3589257/bird-flu-h5n8-europe/"},"headline":"The New Bird Flu Outbreak: Should You Worry?","datePublished":"2014-11-17T19:05:46.000Z","dateModified":"2026-08-04T08:00:22.202Z","description":"So far, bird flu cases in Europe have been identified as the H5N8 strain","url":"https://time.com/3589257/bird-flu-h5n8-europe/","keywords":["flu","Drugs","europe","Infectious Disease","Bird Flu","vaccine"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9864383f2d79d7f2/6987690ca988ca6b636aac35/birds.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt9864383f2d79d7f2/6987690ca988ca6b636aac35/birds.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"birds","caption":"birds","creditText":"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":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/flu/","name":"flu"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3589257/bird-flu-h5n8-europe/","name":"The New Bird Flu Outbreak: Should You Worry?"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"This Flu Shot Is Not Like the Others","description":"Some people may get a new flu shot that’s made with dog cells instead of chicken eggs","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/1thSi60s/poster.jpg?width=720","uploadDate":"2014-10-30T14:53:23.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/1thSi60s.m3u8","embedUrl":"https://time.com/3589257/bird-flu-h5n8-europe/","duration":"PT2M9S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3589257/bird-flu-h5n8-europe/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
