Combat Incorrect Information with this Helpful Tool


Fake news on social media. Social media manipulation and disinformation. Man using laptop computer to post on social media.

Myth: Vaccines are linked to autism.  Truth: In 1998 there was a scientific paper that linked the MMR vaccine to autism. These claims were refuted, and the paper was retracted.

Linda Mota: Champion for Cancer Prevention and Research



On a late October night, Linda Mota woke with a start.  While her mind should have been consumed with choosing a family Halloween costume, her thoughts were elsewhere.  “I was laying down and something inside of me told me, check your side,” she said.   What Linda felt wasn’t overwhelming, but it was clear there was a small lump there, resembling the shape of a little ball.    She initially dismissed what she found, but her intuition continued to scream at her that something was amiss.  “Something inside of me told me, ‘No. you need to get checked, you need to get checked,’” she told herself.  It turned out she had breast cancer.  Linda Mota and Her Startling Breast Cancer Diagnosis and Treatment  Linda was diagnosed with breast cancer in the ...

Since their introduction in the early 1900s, vaccines have helped eradicate diseases.   For this reason, vaccines play a pivotal role in public health, especially for children, the elderly, and the immunocompromised.   However, with the invention of the internet and social media, incorrect information is quickly spread and disseminated, sowing seeds of mistrust in vaccine recommendations. This leads to questions over vaccine research, production, and administration.  What's more, the widespread misinformation about vaccines has caused outbreaks of previously eradicated diseases such as measles, making vaccine uncertainty a serious threat to public health.   In fact, in a recent survey conducted by KFF in collaboration with the Washington Post, 1 in 6 US parents have ...

National Latino Physician Day
