Doctors say some Sask. adults might need measles booster shots

Saskatchewan adults are being urged to check their vaccination records in light of the recent measles outbreak in the province. The Saskatchewan Health Authority (SHA) has reported three cases of measles in March, highlighting the need for individuals to ensure they have sufficient immunity against the highly contagious virus.

One of the challenges faced by the SHA is the lack of childhood immunization records for individuals born before 1978. This poses a dilemma for those who may not have access to their vaccination history, making it difficult to determine if they are adequately protected against measles.

According to guidance provided by the SHA, adults born between 1970 and 1996 are advised to receive a booster shot to enhance their immunity. This is because the vaccination protocol during those years only involved one dose of the vaccine, whereas current recommendations call for two doses for optimal protection.

Dr. Ryan Meili, a family doctor in Saskatoon, emphasized the importance of getting the second dose of the vaccine to reduce the risk of contracting and spreading the virus. Studies have shown that two doses offer better protection compared to a single dose.

Furthermore, Joseph Blondeau, head of Clinical Microbiology at Saskatoon’s Royal University Hospital, highlighted the need for parents to ensure their children are up to date on their vaccinations. Only 75.5% of Saskatchewan children received both recommended doses of the Measles Mumps and Rubella (MMR) vaccine by their second birthday in 2024, falling short of the target needed to achieve herd immunity.

Individuals born before 1970 are generally considered immune to measles due to the widespread nature of the disease prior to public vaccination programs. However, those in high-risk groups, such as health-care workers or international travelers, may still benefit from a booster shot, according to Government of Canada guidelines.

It is recommended that individuals consult their family doctor to determine if they require a booster shot or blood work to assess their immunity. With the recent measles cases in Saskatchewan, it is crucial for older adults to verify their immunity status to protect themselves and others from the virus.

For those with no documented vaccination records, getting the MMR vaccine is considered safe and beneficial. The SHA offers resources for individuals to request childhood immunization records, although records for individuals born before 1978 may not be available.

Measles is a highly infectious virus that can lead to serious complications, including respiratory failure and brain swelling. Vaccination is essential in preventing the spread of the disease, and efforts to maintain high vaccination rates are crucial in protecting public health.

As measles outbreaks continue to pose a threat in Canada and globally, staying informed about vaccination recommendations and ensuring immunity against the virus is essential for individuals of all ages. By taking proactive measures to check vaccination records and receive booster shots as needed, Saskatchewan residents can help prevent the spread of measles and protect themselves and their communities.
