Vaccine monitoring systems, like the Vaccine Adverse Event Reporting System (VAERS), are important to flag potential vaccine-related safety issues. But data from VAERS is often misrepresented to scare people. Let us explain:

It’s normal to have questions about vaccines. Questions like: Are they safe? What are the side effects? What diseases do they prevent?

A misleading rumor is circulating online that Pfizer's COVID-19 vaccine can cause hantavirus. It is true that hantavirus is listed as an adverse event for the vaccine, but it is not a side effect. Vaccine side effects are things caused by the vaccine itself, like mild fever or sore arm.

Happy #MisinformationMonday! Today's topic: new vaccines. A new Lyme disease vaccine is sparking false claims online, including that it is unsafe, that mRNA vaccines are unsafe, and even that tick counts have increased because the vaccine maker released boxes of ticks into the wild to create demand.

A myth has been circulating claiming that the MMR vaccine that prevents measles is more dangerous than measles itself. This is false. Here are the facts:

It's #ScienceAppreciationDay! Immunize Colorado board member Angie is grateful for the science of vaccines because they help keep her daughter -- and those around her -- protected from diseases that might mean hospitalization or worse. Why do you appreciate science?

Some people claim the HPV vaccine is more dangerous than HPV itself. This is not true. Here are the facts:

Today is 3/17 -- a great day to tell Congress to support Section 317 funding! Section 317 is a federal program that supports public health programs across the U.S., including providing free vaccines to uninsured adults and responding to disease outbreaks. It has been severely underfunded for years.

🚨 A judge blocked HHS Secretary RFK Jr.'s recent changes to the childhood vaccine schedule. The changes, not based on any scientific evidence, sowed distrust and confusion for families. This ruling reinforces the importance of making public health decisions with evidence, not misinformation.

It's Monday! Time to tackle more vaccine misinformation. You might have heard the claim that vaccines can lead to an autism diagnosis in young children. Scientists have studied this question for decades and have always found the same answer: no, vaccines and their ingredients do NOT cause autism.

It's another #MisinformationMonday! Today's claim: the Tdap vaccine given during pregnancy is unsafe and can lead to negative outcomes for mom and baby. This is false!

As you read up on things that affect your child’s health, you may come across false rumors or outdated ideas that claim to improve kids' health—especially on the internet and social media. It’s important to find trustworthy, up-to-date information, which can be difficult on social media.

It's Monday! Time to tackle some misinformation. Today's topic? Vaccine safety. Some people claim that no childhood vaccines are tested in placebo trials. This is misleading. Here are the facts:

In January, the federal government announced changes to the recommended childhood vaccine schedule. The changes were made under the guise of restoring trust in vaccines, but were not actually based on new scientific evidence or data. The result has been increased confusion and uncertainty–not trust.

You may have heard that there are new childhood vaccine recommendations. This is only partly true, and there's a big "but."

George Washington required his troops be inoculated against smallpox — that decision helped win the Revolution! Public health leadership isn’t new. It’s presidential. Honoring George Washington this Presidents’ Day for leading with courage and vision.🦅#WeThePeopleVax

Happy ❤️ Day! Show your loved ones you care by making sure you're up-to-date with vaccines. By getting vaccines for yourself, you help protect those around you -- especially those who can't get vaccines or are at higher risk from illness like babies, older adults, and those with chronic illness.

Some vaccines on the federal schedule were recently changed from being universally recommended (meaning for all children) to "shared clinical decision making." This term is confusing, so let's talk about it.

Prenatal vaccines protect mom and baby, who are both at greater risk for complications from vaccine-preventable diseases. This fact sheet in English and Spanish explains which vaccines are needed during pregnancy and when to get them ➡️ buff.ly/tvHfxb0

You might have heard that insurance providers incentivize healthcare providers to give more vaccines. This is only partially true, but ignores the full picture. Here are the facts:

"This will endanger children; we know the consequences all too well." In a Colorado Politics Opinion, a mother and grandmother who lost children to meningitis share their stories and condemn the CDC's recent move to remove meningococcal disease vaccines from the recommended childhood schedule.

You might have heard someone claim that rotavirus vaccines don't work well to prevent infections, or that they're unsafe. This is not true. Here are the facts:

"I talk with Colorado parents regularly, and I know what they want: real information to make the best decisions for their children. They trust their doctors and nurses to give them recommendations backed by science. Elected leaders should be reinforcing that trust, not undermining it."

During the 2024-25 flu season, 289 children died from flu. This is the highest number of pediatric flu deaths since tracking began in 2004. Despite recent federal changes, pediatric and healthcare experts still recommend the flu vaccine for everyone 6 months and older.

“It's like we're going backwards. It's like we have decided we don't want a modern life. We want to be back in the 1950s where children are sick and dying."

Earlier this month, federal health officials unilaterally announced changes to the childhood immunization schedule, removing some vaccines from universal recommendation. You might think this means these vaccines aren't safe and that your child doesn't need them. This is false.

You might have heard that, because immunity from whooping cough vaccines wanes over time, getting immunity from an infection is better. This would be like saying that because you can still get seriously injured in a car wreck while wearing your seatbelt, it's better not to wear one at all.
