CDC measles MMR vaccine possible side effects severe allergic reaction febrile seizure thrombocytopenia

Measles vaccine is usually given as MMR (measles, mumps, rubella) or MMRV vaccine.
Common, mild side effects
  • Pain, redness, or swelling at the injection site
  • Fever, often 7 to 12 days after the injection and lasting 1 to 2 days
  • Mild temporary rash, usually not contagious
  • Swollen glands or mild discomfort
Uncommon or rare side effects
  • Fever-related seizure in young children, about 1 per 3,000 to 4,000 MMR doses. These generally do not cause long-term problems.
  • Temporary low platelet count, which can cause easy bruising or small purple-red spots on skin
  • Temporary joint pain or stiffness, more often in adolescent/adult females receiving the rubella-containing vaccine
  • Severe allergic reaction, extremely rare
Seek urgent care immediately for trouble breathing, facial or throat swelling, widespread hives, collapse, persistent high fever, seizure, or unusual bruising/bleeding.
The vaccine does not cause autism. Overall, it is much safer than getting measles, which can cause pneumonia, encephalitis, hospitalization, and death. The CDC MMR safety guidance and CDC measles vaccine information provide current details.

CDC MMR vaccine rash 7 to 12 days after vaccination

A mild rash after the measles-containing MMR vaccine usually appears 7 to 10 days after vaccination. It can occur anytime around 7 to 12 days.
It is usually mild, lasts a few days, and the child is generally not contagious. If the rash is severe, occurs with breathing difficulty, or there was recent exposure to measles/travel to an outbreak area, contact a clinician. CDC guidance

CDC Epstein Barr virus infectious mononucleosis tonsillitis symptoms

Yes. Epstein-Barr virus (EBV) can cause tonsillitis, usually as part of infectious mononucleosis (glandular fever).
Typical features:
  • Severe sore throat with enlarged, red tonsils, often with white coating/exudate
  • Fever
  • Swollen neck lymph nodes
  • Marked tiredness
  • Sometimes enlarged liver or spleen
It can look similar to streptococcal tonsillitis, so a clinician may use a throat swab and/or blood tests. Avoid taking amoxicillin or ampicillin unless a clinician has ruled out EBV, because these antibiotics often trigger a widespread rash in people with EBV.
Seek urgent assessment for difficulty breathing or swallowing saliva, severe one-sided throat swelling, dehydration, or severe abdominal pain. CDC EBV information

CDC Epstein Barr virus children symptoms infectious mononucleosis

In young children, primary EBV infection is often asymptomatic or resembles a short, nonspecific viral illness.
Possible manifestations include:
  • Fever
  • Sore throat, pharyngitis, or tonsillitis with white exudate
  • Runny nose or cough may occur in younger children
  • Swollen lymph nodes, especially in the neck
  • Tiredness, poor appetite, irritability
  • Mild rash, sometimes more likely if amoxicillin/ampicillin was given
  • Enlarged liver or spleen, less commonly
  • Mild hepatitis with raised liver enzymes, sometimes jaundice
The classic infectious mononucleosis picture, with marked fatigue, exudative tonsillitis, generalized lymph-node enlargement, and splenomegaly, is more common in adolescents than in small children.
In young children, the Monospot test can be falsely negative, so EBV-specific antibody tests may be preferred if confirmation is needed. See the CDC EBV testing guidance.
Seek urgent medical evaluation if there is difficulty breathing, inability to swallow saliva, dehydration, severe abdominal pain, yellow eyes/skin, or unusual drowsiness.
