    Correcting this week’s misinformation: week of July 25, 2024

    How significant were medical visits after vaccination?

    The Claim:

    In a video of a congressional hearing, lawyer Aaron Siri claims the government’s V-SAFEdata showed that 7.7% of participants needed medical care, often emergency or urgent care, after  COVID vaccination.

    The Facts:

    V-SAFE is designed to monitor safety and collect a wide range of health impact data, providing a comprehensive look at post-vaccination health. It collects data on any health events after vaccination, regardless of whether they are related to the vaccine. It’s not solely focused on severe adverse events and does not establish causality. The reported medical visits could be coincidental and not caused by the vaccine.

    The 7.7% figure includes any type of medical care, not just serious cases requiring hospitalization. These could encompass minor issues and precautionary visits.

    Published analyses of V-SAFE data have shown that fewer than 1% of participants reported receiving medical care in the first week after vaccination, and only a very small proportion reported serious outcomes like hospitalization.

    How big are childhood vaccines?

    The Claim:

    leaked video between two presidential candidates makes claims that vaccines given to children are so large that they could be given to horses and that they contain 38 vaccines in one injection.

    The Facts:

    Many of the vaccines given to babies contain about 0.5mL per dose. (Hep BDTaPMMR, etc). The influenza vaccine contains between .25mL and .5mL for those up to 3 years old, 0.5mL for those older than 3, and 0.7mL for those receiving the high-dose version. If you measured out a 0.5 mL dose in a teaspoon, it would only be 1/10 of a teaspoon.

    But to be fair, the horse influenza vaccine contains a dose of 1.0mL, so when you’re looking at quantities that small (1mL is about 20 drops), it’s hard to see that humans do not receive the same amount.

    There are several combination vaccines available; however, 38 is a bit of a wild claim, considering there are only 19 diseases we protect against on the schedule. The vaccine with the most diseases protected against is Vaxalis, which protects against six diseases (Diphtheria, tetanus, pertussis, polio, hepatitis B, and Hib).

    Children today receive far less antigen to protect against more diseases than kids even 30 years ago when the vaccine schedule used 3,000 antigens to protect against 8 diseases by age two. Today, the vaccine schedule uses 305 antigens to protect against 14 diseases in the same timeframe.

    To put this in perspective, children fight off 2,000-6,000 antigens every day just by eating, breathing, and playing.

    Do COVID vaccines cause heart failure?

    The Claim:

    A case study is being used by anti-vaxxers to claim that using endomyocardial biopsy (EMB) reveals COVID vaccines are causing fatal heart failure. 

    The Facts:

    To the best of our knowledge, this is the first reported case of biopsy-proven iDCM following mRNA-1273 immunization.

    The report acknowledges that it has some limitations. First, the researchers couldn’t completely rule out the possibility that the patient had a COVID infection, which might have contributed to her symptoms. Second, they point out that the tests used to diagnose heart inflammation (myocarditis) aren’t always precise or reliable, meaning that some cases might be missed or incorrectly identified. These limitations highlight the challenges in making a definitive diagnosis.

    Additionally, the woman was treated and was stable at follow up with no recurrences a year later. To claim that the case report proves that “fatal cases of heart failures to surge throughout the globe” because of COVID vaccines is false.

    COVID infection itself can cause heart failure or heart attack. Rates of heart disease surged starting in the year 2020, before COVID vaccines were available.
