MMR Shots: Health Unit Urges Updates Before March Break Travel | Collingwood

As March break approaches, health officials are urging families to review and update their immunization records, particularly for measles, mumps, and rubella (MMR). This recommendation comes amid increasing measles activity both internationally and within Canada, raising concerns about potential exposure during travel and community gatherings.

The Simcoe Muskoka District Health Unit in Ontario is actively encouraging residents to ensure they are fully vaccinated against measles. February 20, 2026, the health unit issued a statement highlighting the importance of vaccination, especially given outbreaks occurring in popular travel destinations like Mexico and the United States.

Global Measles Resurgence

Measles cases are on the rise globally, with significant outbreaks reported in several countries. According to data released by Health Canada on February 16, 2026, a combined total of 192 measles cases have been identified in Alberta, Manitoba, Quebec, and Ontario so far this year. This increase is prompting heightened awareness and preventative measures.

The situation is particularly concerning in Mexico, which has reported over 2,700 new cases in 2026, primarily affecting infants and young children. In the United States, more than 900 new confirmed cases have been reported, with notable outbreaks in Florida and South Carolina. The outbreak in Florida is centered around a university near Naples, involving approximately 60 cases, while South Carolina is experiencing its largest outbreak in over two decades, with hundreds of infections reported.

Why Vaccination is Crucial

The MMR vaccine is considered highly effective, providing approximately 97% protection against measles after two doses. In Ontario, the standard immunization schedule includes MMR vaccinations at one year and four years of age. However, individuals who are not protected against measles, mumps, or rubella may face exclusion from childcare, school, or work if an outbreak occurs within the community.

Health officials emphasize that vaccination is not only a personal health measure but also a crucial component of community protection. By achieving high vaccination rates, we can significantly reduce the risk of outbreaks and protect vulnerable populations who may not be able to receive the vaccine, such as infants too young to be vaccinated or individuals with certain medical conditions.

Protecting Yourself and Others

Traveling internationally increases the risk of exposure to measles and potentially bringing the virus back home. Before embarking on any travel, particularly to regions experiencing outbreaks, it is essential to verify your vaccination status and ensure you are up-to-date with the MMR vaccine.

Individuals who are unsure of their vaccination history or require vaccination can contact their healthcare provider or book an appointment at a health unit immunization clinic. Clinics are available in Barrie, Collingwood, Cookstown, Gravenhurst, Huntsville, Midland, and Orillia within the Simcoe Muskoka District Health Unit region.

Understanding Measles

Measles is a highly contagious viral illness that can spread through respiratory droplets produced when an infected person coughs or sneezes. Symptoms typically begin with fever, cough, runny nose, and red, watery eyes, followed by a rash that spreads from the head to the body. Complications from measles can be severe, including pneumonia, encephalitis (inflammation of the brain), and even death.

While the measles vaccine is safe and effective, it’s important to remember that no vaccine provides 100% protection. However, even if a vaccinated individual contracts measles, the illness is typically milder than in unvaccinated individuals.

The current global increase in measles cases serves as a stark reminder of the importance of vaccination in preventing the spread of this potentially serious disease. By prioritizing immunization, individuals can protect themselves, their families, and their communities.

Health officials continue to monitor the situation closely and provide updates as needed. Staying informed and taking proactive steps to ensure vaccination coverage are essential in mitigating the risk of measles outbreaks and safeguarding public health.
