immunization

While the vaccine was first developed in 1963, it wasn’t until 1980 that all 50 states had laws that required measles immunization for school enrollment.

The study also found no adverse effects on lung tissue following immunization, highlighting the vaccine's safety.

Federal health authorities have consistently maintained the immunizations are safe, effective and reduce the risk of severe illness and death.

Health care workers are battling a lack of immunizations compounded by a sanitation crisis.

The immunizations are widely available, and the best time to get vaccinated is in September and October, the CDC says.
