Associate Professor of the Department of Infectious Diseases in Children at Russian National Research Medical University, Doctor Ivan Konovalov—an infectious disease specialist at NI Pirogova—notes that vaccination does not always guarantee lifelong immunity. He emphasizes that checking antibody levels to measles remains a prudent step, even for those who were immunized years ago. The key reason is that antibody levels can wane over time, and when a vaccinated person encounters the virus, they may become asymptomatic carriers. This silent carriage can still prompt a booster in the immune system, helping to maintain protection for the broader community.
Konovalov explains that measuring measles antibodies is advisable for a broad audience, not just healthcare workers or teachers. People who are unsure whether they were vaccinated, or who are uncertain about their antibody status, should consider testing. In children, vaccination typically provides robust protection that lasts for many years, often extending close to adulthood. Yet the reality is that individual immune responses vary, and booster assessments can help confirm ongoing protection, especially in communities with rising measles exposure or outbreaks.
Public health observations in Dagestan in recent years recorded about 200 measles cases, underscoring the importance of monitoring immunity levels within populations and maintaining high vaccination coverage. The overall message from the medical community is clear: staying informed about one’s immune status, promptly updating vaccination when needed, and supporting routine immunization programs are vital steps in preventing outbreaks and safeguarding public health across Canada and the United States. Professionals advise regular antibody checks for those with uncertain vaccination histories, and healthcare systems continue to promote accessible testing and immunization services to ensure communities remain protected against measles and its complications.
