Vaccines are very effective for preventing certain viral infections.
Currently, unfortunately, there is no vaccine for the common cold.
This is largely because more than 200 cold viruses can cause the cold, and it is hard to make a vaccine to target so many viruses.
Scientists are searching for better methods to produce the vaccine, and it will take many years to reach success.
Industry is not willing to invest such a great financial resource to develop the vaccine as the succssful rate is too low to “justify” the investment.
Then, what we can do? Performing nasal cleanse as a habit. No cold viriuses in your nose, no common cold diseases.
