A common cold vaccine, including those for many other types of rhinoviruses, is achievable. Since it is caused by hundreds of different viruses, creating a vaccine for colds was previously viewed as quixotic.
Rhinoviruses are the most common agents of viral infections and the predominant cause of common cold. Other viruses that cause common cold include respiratory syncytial virus (a lungs and respiratory tract infection), parainfluenza virus and adenovirus (cause of illnesses like colds, sore throat, diarrhea, and bronchitis to name a few.)
Idealistic Search For Vaccine?
Because of the many varieties of rhinoviruses, the search for a vaccine was not a priority since there are more illnesses that need a vaccine more. And according to the researchers at Emory University School of Medicine and Children’s Healthcare of Atlanta, our body’s immune system can take care of the viruses.
A couple of years back, creating a common cold vaccine also faced the challenge of rhinoviruses’ diversification as it is too hard to create a vaccine for almost 250 types of colds. In the 1960s, however, researchers found that people can be vaccinated to fight off one type of rhinovirus.
Emory School of Medicine’s associate professor of pediatrics Martin Moore, Ph.D., said it is “surprising” that no one has found or tried to create a “simple solution over the last 50 years.”
Moore and a group of researchers found a way of creating a vaccine for 50 variants of rhinoviruses by mixing enough of each variant into the vaccine.
Nonetheless, the total amount of protein is the same with one dose of vaccine.
The variants, according to Moore, is “like a bunch of slightly different Christmas ornaments” and not like a mixture of 50 absolutely different vaccines.
The study posted in Nature Communications is underway of having “human challenge models with volunteers.” This would easily be doable since the virus is not that pathogenic.
Creating a common cold vaccine may not be urgently important to some medical point of views but it is still valuable to fight off over 200 virus strains that may cause complications.
