Whether a runny nose can be vaccinated or not depends on specific analysis. Firstly, if the baby only has a runny nose, is in good spirits and has no other symptoms, such as fever, cough, vomiting and diarrhea, it is possible to get the vaccine. However, if your baby has a particularly runny nose, such as a very stuffy nose and a hoarse throat, or a fever or cough, or if he or she is in a bad state of mind, as if he or she has no energy or is wilting, it is recommended to hold off on vaccination and not to rush into vaccination. Why? Because babies in a state of illness should not be vaccinated as much as possible. The vaccines given are called vaccines in a good sense, but in a bad sense they are attenuated viruses or bacteria. So, in a normal state of the human organism, a small amount of attenuated, inactivated bacteria or viruses will induce the production of antibodies. However, if a baby is vaccinated in a pathological state, he or she may get sick, for example, hepatitis B may get hepatitis B or may have a higher chance of having a vaccine reaction. Therefore, whether or not a runny nose can be vaccinated depends on whether or not there are accompanying symptoms and how severe or mild they are. If the runny nose is mild and there are no other symptoms, it is possible to get the vaccine; if the runny nose is particularly heavy or even accompanied by other symptoms, such as cough, fever, nausea, vomiting and poor mental state, try not to get the vaccine and delay it for 1-2 weeks, as it will not affect the baby.
