The exceptions in this list are almost entirely due to possible allergic reactions. Take flu vaccines - most of them are created via eggs, so people allergic against eggs cannot use these vaccines, until especially prepared without using eggs. If no vaccine is available for your child, it should skip this especial vaccination. This also is the reason why it is so important that every child which can, should be vaccinated. If a small percentage of the population is not vaccinated, they are still safe&#x2F;no danger to society due to the protection given by the vaccinated part of the population. This is not a reason to skip vaccinations for non-medical reasons.
