From the Research
In Canada, individuals born before 1970, including those who are 88 years old, are generally considered immune to measles and do not require measles vaccination. This recommendation is based on the fact that measles was widespread in Canada before 1970, and most people born before this time were naturally infected with the virus, providing them with lifelong immunity 1. For this 88-year-old patient, no measles vaccination is typically necessary. The measles vaccine (MMR - measles, mumps, rubella) is primarily recommended for those born in or after 1970 who have not been previously vaccinated or who do not have evidence of immunity. Natural infection with measles virus typically confers stronger and more durable immunity than vaccination. However, if the patient is particularly concerned due to local outbreaks, has a compromised immune system, or plans to travel to areas with high measles transmission, they could discuss their specific situation with their healthcare provider. In such cases, antibody testing could be considered to confirm immunity, though this is not routinely recommended for individuals born before 1970.
Some key points to consider:
- Measles is a highly transmissible viral disease, and vaccination is the best way to prevent transmission and complications 1.
- The National Advisory Committee on Immunization (NACI) has updated recommendations for measles post-exposure prophylaxis, including the use of immunoglobulin products for susceptible individuals 2.
- Studies have shown that passive immunization with immunoglobulin products can be effective in preventing measles, especially in high-risk populations such as infants and immunocompromised individuals 3, 4, 5.
- However, for individuals born before 1970, the risk of measles is generally considered low, and vaccination is not typically recommended unless there are specific concerns or risk factors.
It's worth noting that while the provided studies offer valuable insights into measles prevention and treatment, the most relevant and recent study 1 supports the general recommendation that individuals born before 1970 are considered immune to measles and do not require vaccination.
