In our work fact-checking political claims and debunking viral deceptions, we have found a tremendous amount of misinformation on the coronavirus pandemic.
Here’s a guide to our coverage of the facts, including links to our latest stories, FAQs, political claims, videos and expert outside resources. Click on the headlines for the full stories and resources.
These are the most recent stories we published on COVID-19:
FDA Did Not Change Position on Ivermectin Use, Contrary to Online Claims
In response to a civil suit, lawyers for the Food and Drug Administration described the agency’s warnings about the unapproved use of ivermectin to treat COVID-19 as “recommendations.” Although that description doesn’t reveal new information, some conservative outlets have falsely claimed it’s an “outrageous” revelation and a change in the FDA’s position.
Post Omits Paxlovid’s Ability to Protect Against Severe COVID-19, Death
Paxlovid, Pfizer’s COVID-19 antiviral pill, has been shown to prevent severe COVID-19 and death. An online post alleging the drug is a “fraud” and “should be taken off the market” neglects to mention this important information, and falsely says ivermectin is superior.
RSV Surge in Children Likely Caused by ‘Immunity Gap,’ Not COVID-19 Vaccine
Hospitals across the country are seeing a spike of respiratory syncytial virus infections among children. Experts say the spike is most likely caused by an immunity gap created by the lack of exposure to the virus over the past couple of years. There’s no evidence the pediatric COVID-19 vaccine is the cause, as viral posts falsely claim. En español.
COVID-19 Vaccines Reduce, Not Increase, Risk of Stillbirth
There is no link between COVID-19 vaccination and an increased risk of stillbirth, despite such claims online. In fact, vaccination has been shown in multiple studies to reduce the risk of stillbirth by protecting pregnant people and their babies from the coronavirus. En español.
Bodybuilder Died from COVID-19, Not the Vaccine as Social Media Posts Claim
A 62-year-old bodybuilder who had heart disease died after contracting COVID-19. But vaccine opponents are falsely suggesting that he died from the COVID-19 vaccine. He didn’t. He’d been vaccinated 18 months before his death. En español.
Posts Distort Misleading Analysis of COVID-19 Vaccine Safety Data
A rigorous vaccine safety monitoring system has shown that the COVID-19 vaccines are safe and only rarely have serious side effects. But an article shared on social media falsely says that CDC data show more than 18 million people “were injured so badly” by a Pfizer/BioNTech or Moderna COVID-19 vaccine “that they had to go to the hospital.” En español.
Flu Vaccines Given to Prevent Disease, Not Just to Support Pandemic Vaccine Manufacturing
Seasonal influenza vaccines are recommended because they help prevent illness and death. Dr. Robert Malone incorrectly suggested that the annual shots are only given in the U.S. to support vaccine manufacturing in case of an influenza pandemic. En español.

Q&A on At-Home Rapid Test
The demand for at-home, rapid COVID-19 tests — sparked by the fast-spreading omicron variant in December — has continued in 2022. With that demand have come questions about the tests’ efficacy, how to use them and where to get them. We answer those queries and more. En español.
Early Data on Omicron
As many Americans and others around the globe prepare for holiday travel and get-togethers, the omicron variant continues to be a concern. While the available data on transmission, vaccine effectiveness and severity of disease are still preliminary, here’s what we’ve learned so far. En español.
Q&A on the Omicron Variant
On Nov. 24, South Africa told the World Health Organization that amid a recent increase in COVID-19 cases, it had identified a new variant — later named omicron — with a high number of mutations, raising concerns that it could spread more easily than other variants of the coronavirus.

Ongoing Clinical Trials Will Decide Whether (or Not) Ivermectin Is Safe, Effective for COVID-19
Studies on whether ivermectin is beneficial in treating COVID-19 patients haven’t been conclusive, and health officials have warned people not to self-medicate. But multiple large trials are continuing to assess the antiparasitic drug. Yet, Sen. Rand Paul reportedly said researchers were “unwilling to objectively study” it because of “hatred” for Donald Trump. He later acknowledged studies are being done. Here we review the research. En español.
CDC Data Thus Far Show COVID-19 Vaccination Safe During Pregnancy
Federal vaccine monitoring systems have identified no safety concerns with the COVID-19 vaccines for pregnant people. Preliminary Centers for Disease Control and Prevention data show that miscarriage is not more frequent than expected in vaccinated people. Online posts, however, falsely contend that such data, as reported in a CDC publication, show an 82% miscarriage rate. En español.

The Wuhan Lab and the Gain-of-Function Disagreement
A disagreement between Republican Sen. Rand Paul and Dr. Anthony Fauci has put $600,000 of U.S. grant money to the Wuhan Institute of Virology back into the spotlight, while making “gain-of-function” research a household term — all amid calls for more investigation into the origins of SARS-CoV-2. En español.
Evidence Points to Safety of COVID-19 Vaccines for Pregnant People
Clinical trials and medical studies have indicated that the COVID-19 vaccines are safe for pregnant people. But online posts misrepresent unverified reports submitted to vaccine monitoring systems in the U.S. and Europe to misleadingly suggest “920 women” lost babies because they received COVID-19 vaccines. En español.
So Far, Vaccines Remain Effective Against Variants
So far, COVID-19 vaccines have been effective against variants of the coronavirus. Scientists are monitoring the situation carefully, with updated or new vaccines a possibility in the future, if need be. En español.

Research Rebuts Claims Linking COVID-19 Vaccines to Male Infertility
A new study found there was no negative effect on sperm levels in men after receiving the COVID-19 vaccines, undercutting suggestions that the shots affect male fertility. But social media posts have made the baseless claim that vaccinated men “are effectively sterile.” En español.
Q&A on the Rare Clotting Events That Caused the J&J Pause
We look at what is known about the rare clotting conditions associated with the Johnson & Johnson vaccine, their frequency and the risks of COVID-19. En español.
The Facts on the Recommended J&J Vaccine ‘Pause’
So far, nearly 200 million doses of COVID-19 vaccines have been administered in the U.S., including 7.2 million doses of the Johnson & Johnson vaccine. In six cases there have been reports of “a rare and severe type of blood clot” in those who received the J&J vaccine, prompting the Food and Drug Administration and Centers for Disease Control and Prevention to recommend “a pause in the use” of the J&J vaccine “out of an abundance of caution.” We review the facts of this rare condition that caused the pause. En español.

A Guide to Pfizer/BioNTech’s COVID-19 Vaccine
The first COVID-19 vaccine to go into any American arms outside of a trial — and the first to be fully approved by the Food and Drug Administration — is Pfizer’s mRNA vaccine, which was designed and developed by the German biotech company BioNTech. Here, we give a rundown of basic facts about the vaccine and an overview of how it works. En español.
No Evidence Vaccines Impact Fertility
Q: Do the COVID-19 vaccines cause infertility?
A: There’s no evidence that approved vaccines cause fertility loss. Although clinical trials did not study the issue, loss of fertility has not been reported among thousands of trial participants nor confirmed as an adverse event among millions who have been vaccinated. En español.
The Evolving Science of Face Masks and COVID-19
Since the Centers for Disease Control and Prevention began recommending that members of the public mask up last spring, additional research has backed the use of face masks to combat the coronavirus. While knowledge gaps still remain, experts agree that masks should be used — and increasingly, they are emphasizing the use of better masks. En español.

Since the outbreak of the coronavirus, Trump has questioned the effectiveness of masks, touted unproven treatments and criticized his own health experts. Here is the timeline of the president’s comments on COVID-19.
Q&A on COVID-19 Antibody Tests
President Trump says antibody tests “will help us assess the number of cases that have been asymptomatic or mildly symptomatic, and support our efforts to get Americans back to work by showing us who might have developed the wonderful, beautiful immunity.” But so far, the tests are not widely available — and many of those that are available do not work as advertised.
The Facts on Coronavirus Testing
We explain how testing works, what happened with the CDC’s coronavirus test and what’s known about how many tests are available in the U.S.
No Evidence to Back COVID-19 Ibuprofen Concerns
There is no evidence that ibuprofen or other non-steroidal anti-inflammatory drugs can make COVID-19 cases more severe. You should consult your doctor before changing medications.
Does Vitamin D Protect Against COVID-19?
Some scientists have hypothesized vitamin D might be helpful, but there is no direct evidence that vitamin D can prevent COVID-19 or lessen disease severity. Nevertheless, it should be part of a healthy lifestyle.
No Evidence That Flu Shot Increases Risk of COVID-19
A claim being pushed on social media and by an organization skeptical of vaccines is using a military study to falsely suggest that the flu vaccine increases someone’s risk of contracting COVID-19. The study does not say that, and the Military Health System advises people to get the flu shot.
Baseless Conspiracy Theories Claim New Coronavirus Was Bioengineered
Several online stories inaccurately claim that the new coronavirus contains HIV “insertions” and shows signs of being created in a lab. But there is no evidence that the new virus was bioengineered, and every indication it came from an animal.

Some of our most popular stories on claims made by politicians include:
Biden’s False Claim on Trump’s Response to Coronavirus
Former Vice President Joe Biden was wrong when he said that the Trump administration made no effort to get U.S. medical experts into China as the novel coronavirus epidemic spread there early this year.
Trump’s H1N1 Swine Flu Pandemic Spin
The president made false and misleading comparisons between his response to the new coronavirus and President Barack Obama’s handling of the 2009 H1N1 influenza pandemic.
The Facts on Trump’s Travel Restrictions
The president has made a number of misleading statements about his decision on Jan. 31 to impose travel restrictions related to the novel coronavirus epidemic.
False Claim About CDC’s Global Anti-Pandemic Work
Democrats have said that the Trump administration cut the CDC’s anti-pandemic work in over 40 countries to just 10. The CDC told us that’s not true.
Trump Falsely Claims He Inherited ‘Empty’ Stockpile
More than once, President Donald Trump has falsely claimed that the federal stockpile of emergency medicine and supplies he inherited from his predecessor was an “empty shelf.”
Democrats’ Misleading Coronavirus Claims
Democrats have criticized President Donald Trump for his administration’s response to the new coronavirus, making claims about cuts to public health programs and the silencing of government experts. But they haven’t always gotten their facts right.
Trump’s Statements About the Coronavirus
President Donald Trump said on March 17, “I felt it was a pandemic long before it was called a pandemic.” While it’s not possible to know what Trump “felt,” there’s no doubt that Trump had minimized the threat of the new coronavirus for weeks in statement after statement.
Trump and the ‘New Hoax’
Democratic presidential candidates harshly criticized President Donald Trump for using the term “hoax” in connection with the coronavirus outbreak. There’s no question that the president described the disease as the Democrats’ “new hoax” at a political rally on Feb. 28 in South Carolina. But Trump said that when he used the word “hoax,” he was referring to Democrats finding fault with his administration’s response to coronavirus, not the virus itself.
