The article “Long-lasting flu vaccine could replace yearly shots”, by Alison Pearce Stevens, was published on January 10th. In the article scientists did an experiment that could determine if we needed to get yearly flu shots. Scientists were working on a vaccine which helps the immune system to recognize a virus, so that the body can destroy the infection before it takes hold of you. In the experiment scientists used 4 out of 18 subtypes of flu, which were the most common to cause diseases in people. After observing the strains researchers got the “average set of flu genes and put them into an artificial virus.”, for the second part of the experiment scientists modified the genes in the artificial virus so that they wouldn’t cause illness. After doing this they put it into another virus called a vector. They use the vector, which was a virus that causes colds, so that the DNA can be put into cells. This is how the scientists made a vaccine to the artificial virus. To see if it worked they tried it out on mice. They gave some mice varying amounts of the vaccine and then distributed other different types of vaccines equally. The vaccines were FluMist and FluZone. After a month the scientists noted that mice who got FluMist and FluZone died, and mice with a light amount of the new vaccine made it through 7 of the 9 viruses. The mice with a high does of it survived. Researchers concluded that this vaccine protected the mice very well, but it’s not ready for people to use. The reason for this is because of the vector they used, a common cold virus. When people get to the age of legally being an adult one-fifth to half of them will have already encountered the viruses. So even if the vaccine is in it the virus will be attacked before it has the opportunity to help them. Because of this CDC (Centers for disease Control and Prevention) wants to turn this vaccine into something that is used in folks childhood, so then by the time they are an adult they will have immunity to the virus for life. With this as the ultimate goal scientists continue to look at antibodies. This article is interesting because it’s current and it can draw anybody’s attention since it talks about the flu shot. I picked this article because it talked about health and better ways to improve the vaccine than it already is doing annually. News like this should be heard because young and old people have the weaker immune systems, and knowing that you can have immunity to the flu virus for a lifetime is a big deal. Ways that this topic can be spread is by telling parents and then letting kids know. By doing this scientists are able to achieve their goal by making it a vaccine used in childhood. By reporting it you keep us up to date with what’s happening in our bodies every year as the vaccine evolves. This should be something we pay attention to because we have to get the flu shot yearly and kids may not like that, so telling them about ‘just getting it once will have you secure’ will most likely make them want to tell everybody. Overall this is news everyone should talk about because it affects everyone and keeps us healthy.
