Suspected Measles in Tucson Toddler Turns Out to Be Rare Vaccine Reaction

Pima County health officials announced on Tuesday that a one-year-old child previously suspected of having measles actually experienced a rare side effect from the MMR vaccination. The child is recovering well and has gained 93% protection against measles from the first vaccine dose.

The Pima County Health Department (PCHD), in conjunction with the Arizona Department of Health Services and a local hospital, took extensive precautions during the child’s treatment, initially treating it as a potential infectious case until tests ruled out active measles. Dr. Theresa Cullen, PCHD’s director, expressed relief, noting that this incident serves as a crucial reminder of the importance of vaccination.

Officials emphasized that vaccination is essential to prevent measles, especially amid outbreaks occurring in various states. They clarified that while side effects from the MMR vaccine can mimic measles symptoms like fever and rash, they are not contagious and occur in about 5% of cases.

Currently, Pima County is on high alert for potential measles cases following recent outbreaks that have affected over 400 individuals in Texas and New Mexico, leading to one child fatality in Texas. Other states, including California and Florida, have also reported measles cases, underscoring the need for increased vigilance in vaccination.

While no confirmed cases have emerged in Arizona this year, health experts caution that a decrease in the immunization rate among children poses a significant risk. Measles is highly contagious and can be transmitted through direct contact or even through the air. Officials state that unvaccinated individuals face a 90% likelihood of infection upon exposure.

The effectiveness of the MMR vaccine is significant, with two doses providing 97% immunity. To ensure community safety, vaccination rates must exceed 95%, according to health authorities. In Pima County, the kindergarten vaccination rate currently stands at 92.8%, indicating room for improvement.

Pima County health officials have limited available vaccine supplies, primarily administering shots to young children. Adults seeking the MMR vaccine are advised to consult their doctors or local pharmacies. Clinics like Walgreens and CVS have confirmed availability of MMR shots.

Legal requirements for kindergarten entry in Arizona mandate that children receive two doses of the MMR vaccine, along with several other vaccines. Parents can opt for personal belief exemptions or medical exemptions under certain circumstances.

Vaccine misinformation has contributed to a decline in vaccination rates in Pima County since 2019. Crystal Rambaud, PCHD’s immunization program manager, linked the drop to factors such as vaccine hesitancy and disruptions caused by the COVID-19 pandemic. Current data indicates that only 2% of measles cases nationwide involve individuals who have received two doses of the MMR vaccine.

Pima County’s MMR vaccination rates have fallen, highlighting the urgent need for increased community awareness and education about vaccination benefits. Measles remains one of the most contagious diseases, with symptoms including high fever, cough, and rash appearing one to two weeks after exposure.

Arizona’s MMR vaccination rate for kindergartners is currently among the lowest in the nation, raising concerns for public health officials. Detailed statistics show significant vaccination gaps in specific counties, where rates drop below 90% can significantly elevate outbreak risks.

In light of misinformation surrounding vaccines, health officials continue to advocate for accurate information and community awareness initiatives. Vaccination is vital not only for protecting individual children but also for safeguarding vulnerable populations who cannot receive vaccines for medical reasons.
