Anti-vaccine claims about the Alexis Lorenze case mislead on vaccine risks

Introduction In September 2024, multiple social media posts began appearing on Instagram, claiming that vaccination caused a 23-year-old woman named Alexis Lorenze to become severely ill. These posts commonly included graphic photos of Lorenze’s facial bruising and swelling. Several of these posts can be traced to accounts with large followings that previously spread health misinformation, … Continued

Decline in autism among high-income white households not caused by a decrease in childhood vaccination, vaccines don’t cause autism

Autism spectrum disorder (ASD) is a neurological disorder that usually becomes apparent in early childhood. It affects an individual’s ability to behave, interact, and communicate with others. Although the causes of ASD remain elusive at this time, medical and epidemiological studies have shown that vaccines don’t cause ASD. The prevalence of ASD may differ between groups of different wealth and race in the U.S. However, because evidence shows us that vaccines don’t cause ASD, a correlation between ASD prevalence and vaccine coverage is simply coincidental rather than an indication of a causal relationship.

Studies show flu vaccine reduces risk of flu-related illness and hospitalization; benefits of flu vaccine outweigh its risks

Flu viruses mutate constantly, making it necessary for new flu vaccines to be developed every year. Flu vaccine effectiveness heavily depends on how well the vaccine targets circulating flu viruses during the flu season. Data from multiple flu seasons show that the vaccine is generally effective at reducing flu-related risks and protecting people at a greater risk of flu-related complications., which is particularly critical for groups at a higher risk of flu-related complications, such as young children and pregnant women.

Facebook reel misinterprets patents for proposed therapies and vaccines as patents for viruses

Patents are often filed by individuals or groups to protect an invention. This prevents the invention from being commercially exploited by others without the patent owner’s consent. However, a patent can also be filed for products of nature like viruses and for other reasons apart from restricting the use of an invention. For example, public health agencies like the U.S. Centers for Disease Control and Prevention patent viruses to keep samples accessible to researchers, preventing a single party from monopolizing samples and restricting research efforts.

A cancerous tumor is a mass of cancer cells, not “toxins”; biopsies and mammograms don’t cause cancer

Many types of cancer produce solid tumors that are primarily made up of cancer cells, which are cells that multiply uncontrollably due to mutations. These tumors also contain blood vessels that carry nutrients and oxygen to the cancer cells, as well as other cells that support the growth of cancer cells. Biopsies and mammograms are useful tools for early cancer detection, but also carry certain risks that should be evaluated for each patient. However, they don’t cause cancer.

Preclinical studies cannot provide sufficient evidence that ivermectin helps treat cancer in people

Ivermectin is an attractive cancer drug candidate as it’s inexpensive and already clinically approved, albeit for parasitic infections. Some preclinical studies have indeed found promising results using ivermectin, but these studies were done in cell cultures and animals, not in humans. As such, they cannot provide sufficient evidence that ivermectin helps treat cancer in people. Further studies are needed to reliably determine ivermectin’s effectiveness and safety when used to treat cancer in humans.

False claims that pandemic treaty abolishes nations’ sovereignty and allows WHO to impose health policies circulate on social media

The COVID-19 pandemic exposed shortcomings in pandemic preparedness and response in countries around the world. In December 2021, WHO Member States established and are leading a process to write a pandemic accord to address these shortcomings and improve pandemic prevention and preparedness. Contrary to popular claims online, the accord affirms national sovereignty and the right of each country to enact its own health policies.
