Hello. Thank you for your question. It is not likely that your son's symptoms are due to the vaccines. His history of congestion for the past few days indicates that he probably has a viral illness. Eye symptoms like the ones you describe are commonly seen in combination with viral upper respiratory infections. The task is to keep the eye clean so that it does not become susceptible to bacterial infection. If in doubt, or if the symptoms worsen over the next 2-3 days, I recommend consulting with your doctor.
