Baby Alba Moss was rushed to hospital after her fever soared to a life-threatening 107°F (approximately 42°C). What started as a “simple illness” quickly turned into every parent’s nightmare.

Her tiny body became swollen and unresponsive. Her eyes shut completely for days. She struggled to breathe and required oxygen support. At one point she did not react at all. Despite multiple hospital visits, her condition was initially misdiagnosed. It was only when the situation became critical that doctors confirmed the diagnosis: measles.

Alba, then about 11 months old and living in the London area with her parents Jilly and Richard Moss, was still too young to receive the first dose of the MMR vaccine. She had no personal immunity against the highly contagious virus. After developing a high fever and rash that spread across her body, she was admitted to Chelsea and Westminster Hospital, where she spent around eight days receiving intensive supportive care. This included oxygen, intravenous fluids, tube feeding, vitamin A to reduce the risk of eye complications, and close monitoring for serious complications such as pneumonia or encephalitis.

Her mother later described the experience as “absolutely horrific,” noting that Alba’s eyes remained swollen shut for four days and that the family feared they might lose her. Alba eventually recovered and was discharged, though the ordeal left a lasting impact on her parents, who shared photographs of her illness to highlight the dangers of measles for infants too young to be vaccinated.

Measles remains one of the most infectious diseases known. While most people recover, it can cause severe complications, particularly in babies, and is preventable through vaccination. Infants under 12 months rely on community (herd) immunity for protection until they are eligible for the MMR vaccine. Alba’s case, widely reported in 2019, underscored both the vulnerability of unvaccinated young children and the importance of maintaining high vaccination rates to protect those who cannot yet be immunized.
