Abstract:
After the administration of efficient and reliable vaccines many of the infectious diseases have declined dramatically. Measles in the developed countries has declined also dramatically since the introduction of measles vaccine, but still remains an important pediatric problem. When given at age 15 months or later, the live further attenuated virus vaccine provides durable immunity in over 90 percent. Measles vaccine failure has been associated with the use of inactivated measles vaccine vaccination before 1 year of age and errors of vaccine handling.
Insights
Measles vaccination, when administered at 15 months or later, offers durable immunity in over 90% of children. Vaccine failures are linked to early vaccination with inactivated vaccines or improper handling.
Area of Science:
- Pediatric infectious diseases
- Vaccinology
- Immunology
Context:
- Measles, despite widespread vaccination, remains a significant pediatric health concern in developed nations.
- The introduction of measles vaccines has led to a dramatic decline in measles cases.
- Challenges persist in achieving complete measles eradication due to vaccine failure factors.
Purpose:
- To summarize the efficacy and challenges associated with measles vaccination.
- To highlight the optimal timing and vaccine types for durable measles immunity.
- To identify factors contributing to measles vaccine failure.
Summary:
- Live-attenuated measles virus vaccines administered at 15 months or older provide durable immunity in more than 90% of individuals.
- Measles vaccine failure is associated with prior vaccination using inactivated measles vaccines before one year of age.
- Improper vaccine handling and administration errors can also compromise vaccine effectiveness.
Impact:
- Understanding optimal vaccination strategies is crucial for controlling and potentially eradicating measles.
- Identifying causes of vaccine failure can inform public health policies and clinical practice guidelines.
- Ensuring proper vaccine handling and timely administration are key to maximizing population immunity against measles.
