Continuing mumps outbreak in Keralam leads to renewed demand for MMR vaccine
The demand has gained strength following studies from Keralam documenting immunity gaps among children, complications that can cause long-term disability, and genetic differences between the circulating mumps virus and the strain used in the vaccine, indicating how the continued exclusion of MMR vaccine from Universal Immunisation Programme represents an important gap in disease prevention
Keralam is currently experiencing a continuing mumps outbreak that has led to a renewed demand for the MMR vaccine, as documented by recent studies. The outbreak began in late 2023 and has persisted into 2026, causing the closure of schools and hostels in several districts including Alappuzha, Thrissur and Kottayam. The demand for the MMR vaccine has gained strength due to the documented immunity gaps among children, potential long-term disabilities caused by the disease, and genetic differences between the circulating mumps virus and the strain used in the vaccine.
These differences indicate that the exclusion of the MMR vaccine from the Universal Immunisation Programme (UIP) represents a significant gap in disease prevention.
