COVID-19 mRNA vaccines were tested in clinical trials, aren’t experimental

Clinical trials and ongoing vaccine monitoring efforts show that COVID-19 vaccines are effective at reducing a person’s risk of severe disease and death. Like any medical intervention, vaccines also come with risks. While COVID-19 mRNA vaccines are linked to a slight increase in the risk of myocarditis (inflammation of the heart muscle), COVID-19 itself is associated with a greater risk of heart inflammation and other health complications. On balance, the benefits of the COVID-19 mRNA vaccines outweigh their risks.

Modified RNA in COVID-19 vaccines aren’t linked to cancer development

The mRNA COVID-19 vaccines contain RNAs with chemical modifications that increase their stability and improve their ability to induce a potent immune response. Some results suggest that such chemical modifications make mRNA-based anti-cancer vaccines less effective. However, it doesn’t mean that COVID-19 vaccines increase the risk of cancer. There’s no evidence that COVID-19 vaccination increases the risk of cancer.

No evidence budesonide, clarithromycin, and aspirin combination is “silver bullet” for COVID-19, contrary to Texas doctor’s claim

Randomized controlled trials are considered the gold standard when it comes to testing the safety and effectiveness of a medical treatment. Unlike anecdotes, randomized controlled trials contain several safeguards, such as experimental controls, blinding, and randomization, which help to reduce the risk of bias and improve the reliability of a trial’s findings.

Virologist Geert Vanden Bossche makes unsupported prediction that mass COVID-19 vaccination will cause an immune “collapse”

Immunity from either COVID-19 vaccination or from infection, exerts selective pressure on a virus and can drive viral evolution, potentially leading to new variants. However, not vaccinating and allowing the virus to spread freely carries the risk of severe disease and death and would also increase the virus’ opportunities to mutate. COVID-19 vaccines, while imperfect, help reduce the spread of the virus and the risk of severe illness and death.

Country-to-country comparison doesn’t show that COVID-19 vaccines are ineffective, contrary to Facebook post by journalist Sharyl Attkisson

When comparing country-level COVID-19 data, care must be taken when drawing conclusions because such analyses come with a high risk of bias. It is important to account for many factors, such as COVID-19 testing policy, each country’s age distribution, and compliance with COVID-19 preventive measures, because these are all factors that affect COVID-19 outcomes reported in each country.

Are claims linking recent U.S. trends in cancer diagnoses to COVID-19 vaccines plausible? A look at the available data

Claims questioning COVID-19 vaccine safety have circulated continuously since COVID-19 vaccination campaigns began at the end of 2020. One such claim suggests that there has been an unprecedented rise in the number of cancer cases after the COVID-19 vaccine rollout, implying that the vaccines are responsible for this phenomenon. Science Feedback previously explained why this … Continued

No, a court didn’t rule that the FDA broke the law with advisory warning against using ivermectin for COVID-19

Ivermectin is approved for treating parasitic infections in people. During the COVID-19 pandemic, some promoted ivermectin as an effective drug to treat COVID-19. Some physicians also prescribed the drug “off-label” for COVID-19. However, there is a lack of reliable scientific evidence to support using ivermectin to treat COVID-19. Ivermectin isn’t approved or authorized by the U.S. Food and Drug Administration for treating COVID-19.
