Canadian health groups say a new US rule on child vaccines is not supported by evidence. Canada's vaccine rules will stay the same.

US President Donald Trump signed a new order on vaccines for children. It suggests giving vaccines at separate doctor visits.

The Canadian Paediatric Society supports Canada's current vaccine schedule. It says this schedule is based on scientific evidence.

The society says giving all recommended vaccines on time is the best way to protect children from serious illnesses.

The Canadian Public Health Association is also concerned about Trump's order.

The association says the new US rules are not based on current evidence. It advises Canadian parents not to change their children's vaccine schedules.

The head of the World Health Organization criticized Trump's order. He said it does not align with decades of evidence on vaccines.

Delaying vaccines does not make them safer and can leave children unprotected.

In the US, children usually get their first MMR vaccine between 12 and 15 months old. The second dose is given between 4 and 6 years old.

Trump's new order suggests separating the MMR vaccine into three shots given at different visits.

The order also says one-year-olds should get their shots in five separate visits. But it's not clear which vaccines this applies to.

There are no separate measles, mumps, and rubella vaccines available in the US right now.

US states, not the federal government, decide if vaccines are required for schoolchildren. The order advises states to consider updating their laws.

MMR is a vaccine that protects against measles, mumps, and rubella.

In Canada, babies under 6 months are not vaccinated because their mothers' antibodies can interfere with the vaccine.

Babies under 12 months are not given measles vaccines in Canada.

Children between 12 months and 13 years should get two doses of measles vaccine.

The first dose should be given at 12 to 15 months, and the second dose at 18 months or later.

Children who missed their routine vaccines should also get two doses of measles vaccine.

Health Canada says Canada's vaccine recommendations will not change because of Trump's order.

Canada's vaccine recommendations are based on the best available evidence. Childhood vaccines are crucial for preventing illnesses.

Measles cases have increased in recent years, leading to changes in US vaccine policy.

As of August 1, 1,114 measles cases were reported in Canada.

Canada lost its measles elimination status in 2025 due to ongoing transmission of the virus.

Over 5,000 measles cases were reported in Canada in 2025, across many provinces.

Canada can regain its measles elimination status if it stops the current outbreak for at least a year.

The Pan American Health Organization warned countries to strengthen their vaccine and outbreak response measures.

Guatemala has the most measles cases in the Americas, followed by Mexico and the US.

The number of measles cases in the Americas is the highest since 2004.

As of July 18, 2026, the Americas reported 47,459 confirmed measles cases and 44 deaths.

The PAHO released a similar alert on February 3.

The US had a large measles outbreak that ended in April 2026, with nearly 1,000 cases reported.

There was another outbreak in West Texas, with over 760 cases and two deaths.

The US recorded over 2,000 measles cases in 2025, the most since 1992.

A total of 2,144 confirmed measles cases were reported in the US in 2025.

This is a 652% increase from 2024, when 285 cases were reported.

Most of the cases were in 45 US jurisdictions, and 25 were in international visitors.
