Hello, First of all thank you for your question. Your daughter has had a fever for 24 hours, and this is 7 days after she received her 1 year vaccines. First of all how high is your daughter's temperature? And is the temperature taken by rectal view Generally, if the immunization schedule she is following is for children born after June 1, 2019, several vaccines are given at 1 year of age which are Dcat-VPI-Hib (booster dose), pneu-c-13 (booster dose) and MMR-Var. MMR-Var (which protects against measles, mumps and rubella) can cause fever 4 to 12 days after vaccination. So it's possible that your daughter's fever is due to the vaccine, but it could also be due to something else, such as a viral infection. If your daughter seems to be feeling ill, Tylenol may help. Note that if the fever lasts 48-72 hours or her general condition changes (headache, pale complexion, irritability, etc.), it would be best to see the doctor. I will be available for any other questions if needed. Happy day to you, Justine Desharnais Familiprix Mont-Tremblant According to the fever thresholds presented by CHU Sainte-Justine, a child her age has a fever if her temperature is equal to or greater than 38.5°C (rectally). So good news if she does not have one on Saturday as well as today. Feel free to get back to us with any other questions you may have. Happy evening to you, Justine
