A child at my daughters school was confirmed to have german measles on tuesday. my daughter had her mmr and chickenpox vaccination on tuesday evening. the sister said she will not get a fever from either of the vaccinations but today she has a fever?

Some basics: About 5-15% of kids given the MMR & V will have fever 39.4c or higher 6-12 days after the vaccine. It is not unexpected or particularly worrisome as it indicated a reaction by the immune system. Any fever that occurs prior to this interval may represent an illness to which the child was exposed that has finally emerged. I would handle the fever with supportive care & report the reaction to her doc

Vaccine reaction: German measles is fairly benign and only moderately contagious. Your sister is wrong; fever is common after the MMR, which can also have many other side effects.See https://tinyurl.com/y8p638hu and https://tinyurl.com/y6nl6p35 Your daughter is now infected with 4 live viruses from these vaccines but should handle it. I advise not giving medicine to lower her fever as fever helps fight infections.
