With over 200 different kinds of viruses that make up the common cold, Science is struggling to find a cure.

Adults suffer this elusive, widespread, and infectious disease 2 to 4 times a year, and children up to 10 times.

Scientists to date have identified seven virus families that cause the majority of colds:

• rhinovirus
• the new 2019
• influenza
• parainfluenza
• adenovirus
• respiratory syncytial virus (RSV)
• metapneumovirus.

For Doctors, vaccines are preferable to drugs as they protect the host even before any infection.

For Pharmaceutical companies (Big Pharma), vaccines don't spell money, as much as over-the-counter drugs and treatment do.

Due to a low possibility of any success, and spectacular failures in the last 100 years, pharma companies are wary of investing time, resources and capital in any new research for the common cold.
