Detailed explanation-1: -It will be difficult to develop the vaccine because rhinovirus infects quickly and mutates, or changes quickly. In clinical trials that tested a cold vaccine with just one strain, results showed that it was not protective.
Detailed explanation-2: -A vaccine to prevent the common cold has been difficult to make, primarily because there are more than 200 different varieties of viruses that can cause colds.
Detailed explanation-3: -Colds are minor infections of the nose and throat caused by more than 200 different viruses. Rhinovirus is the most common cause, accounting for 10 to 40 percent of colds. Other common cold viruses include coronavirus and respiratory syncytial virus (RSV).
