There is no vaccine for th4e common cold but yu can take precautions to slow the spread of cold viruses.
Wash your hands. Wash your hands thoroughly and often with soap and water for at least 20 seconds. If soap and water aren't available, use an alcohol-based hand sanitizer that contains at least 60% alcohol. Teach your children the importance of handwashing. Avoid touching your eyes, nose, or mouth with unwashed hands.
Disinfect your stuff. Clean and disinfect high-touch surfaces, such as doorknobs, light switches, electronics, and kitchen and bathroom countertops daily. This is especially important when someone in your family has a cold. Wash children's toys periodically.
Cover your cough. Sneeze and cough into tissues. Throw away used tissues right away, then wash your hands thoroughly. If you don't have a tissue, sneeze or cough into the bend of your elbow and then wash your hands.
Don't share. Don't share drinking glasses or eating utensils with other family members. Use your own glass or disposable cups when you or someone else is sick. Label the cup or glass with the name of the person using it.
Stay away from people with colds. Avoid close contact with anyone who has a cold. Stay out of crowds, when possible. Avoid touching your eyes, nose and mouth.
Take care of yourself. Eating well and getting exercise and enough sleep is good for your overall health.
If you have concerns, you should always consult your medical professional.
