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.
The common cold is an upper respiratory tract infection of viral origin, usually caused by a rhinovirus (up to 40% of colds), or by Coronaviruses (about 20%). These are the more common viruses, but there are more than 200 different viruses (some say as many as 700) that can cause the common cold. There are a huge number of different viruses from a number of different viral 'families' that cause cold symptoms. This is the main reason there is no vaccine for the common cold - there are simply too many different viruses to develop vaccines specific to each virus, and before a vaccine can be developed for a new viral mutation, it can mutate again.
The first vaccine is the virus cowpox (the latin word for cow is vacca, hence vaccine). It produces a very mild and harmless infection in people but protects them from smallpox, one of the most deadly diseases in history. Today, smallpox has been eradicated from the wild due to a worldwide effort to vaccinate enough people to wipe it out.
There is no specific vaccine for viral pneumonia, but vaccines such as the influenza (flu) vaccine and the measles vaccine can help prevent some of the viral infections that can lead to pneumonia. It is important to practice good hygiene, get vaccinated, and seek medical attention if you develop symptoms of pneumonia.

Albert Sabin founded the oral polio vaccine and the vaccine was licensed in 1962.
Live attenuated influenza vaccine (LAIV) is a type of influenza vaccine in the form of a nasal spray that used to be recommended to prevent influenza.
Like all influenza viruses it has a roughly spherical shape.

One code is 90471. There is a 2nd code for the actual influenza vaccine, but we need to know the age of the patient.
Influenza A virus H5N1, is known as "bird flu". H5N1, is a subtype of the influenza A virus which can cause illness in humans and animals. A filtered and purified influenza A vaccine for humans is being developed.
Dr. Rosenow in 1918
Influenza vaccine, intramuscular
Intramuscular.
Adults should get seasonal influenza vaccine annually.
Vaccination is only a preventative measure, it will not cure influenza.
