Remember that a virus is a living organism, and like all living organisims they are constantly growing and adapting to its environment. As time progresses, the virus that causes the flu is adapting, strengthening, and becoming immune to the vaccines that we created. Thus each year the vaccine must be adapted to match the development of the strain. However, there are different types of the flu and if we do not have a particular strain in the lab (remember the Swine Flu?) we cannot create a vaccine to counter it. Thus it becomes more difficult every year to produce larger quantities (as our population is ever increasing) of a new vaccine.
What else can I help you with?
Is there a vaccine for the common cold?
No. There is a vaccine for the flu and H1N1, but not for the common cold. But all you need for the common cold is TLC and a little bit of orange-flavored Delsum. :)
Why would it be difficult to find a vaccine to be used against the common cold?
Because such a wide-spread virus would be constantly mutating.
Why it is possible to develop a vaccine to prevent smallpox but it is difficult to develop a vaccine to prevent the common cold?
Developing a vaccine for smallpox was feasible because the virus, Variola, has a stable and well-defined structure, allowing for effective targeting by the immune system. In contrast, the common cold is primarily caused by a variety of viruses, predominantly rhinoviruses, which mutate rapidly and have numerous strains. This genetic variability makes it challenging to create a single vaccine that would be effective against all possible variants. Additionally, the common cold typically causes mild symptoms, reducing the urgency for vaccine development compared to more severe diseases like smallpox.
Why is there no immunisation for colds?
because there are too many types of the common cold to make a vaccine.
Why is vaccine developed for influenza but not for rhinovirus?
Because the rhinovirus (which is one virus that causes the common cold) mutates and changes its structure extremely frequently as do the other viruses that cause the common cold, such as Coronaviruses, and any of the others of hundreds of viruses that cause colds. While influenza strains also mutate, it is not as quickly as cold viruses that almost constantly are mutating, resulting in several dozen active viruses in any one locality. In addition, influenza has proven reasonably easy to grow in labs for study and for vaccine production, while cultivating rhinoviruses has proven very difficult.
Why is it that a new vaccination for the common cold needs to be made every year?
Common cold is caused by a virus. Viruses, when infecting people, constantly change, so scientists always have to make a new vaccine.
What is the cold sore vaccine?
At the end of 2013, there is no commercially available vaccine for herpes simplex, the virus that causes cold sores.
What is the differences between vaccine and injections?
Injections are given for treatment while vaccines are given to produce antbodies to protect the recipients from specific diseases
Do flu viruses have a high mutation rate?
Yes, viruses do mutate very easily. This is one reason the cure for the common cold is so elusive, before a vaccine can be created for the strain of rhinovirus or other virus that is causing the currently circulating common cold, the viruses will have often mutated to a new form making a vaccine ineffective.
Can viruses be cured by vaccines?
No. Vaccinations are for preventing infectious diseases, not treating or curing them.
Is there a vaccine to prevent s croup or cold?
the answer is no.
What is the most common respiratory system disease?
Quite simply because it is not "the" common cold. There are over 300 different 'common cold' diseases. That, by the way, is why you cannot create a vaccine for the cold. Once you have had one of the 300+ colds, you are immune to it, and will never catch it, again. Since there are over 300 common cold diseases, there are many more of them than any other respiratory ailments.
