4 COVID-19 Myths You Should Stop Believing

You’ve probably heard some theories about COVID-19 that sound outrageous. With a lot of unknowns about the virus, you may wonder about the truth behind these claims. It is important to know what is true and what is not. Here we set the record straight.
  1. Myth: COVID-19 is just like a cold or the flu.
    Fact: Since the early days of the pandemic, we’ve all heard many comparisons of COVID-19 to the flu or a cold. But, while most people with COVID-19 have mild symptoms, COVID-19 is far deadlier than the flu. The Centers for Disease Control and Prevention (CDC) estimates that the flu causes roughly 12,000 to 56,000 deaths per year in the United States. So far, in the U.S., COVID-19 has caused more than half a million deaths, with thousands more reported each day.
  2. Myth: If we just let the virus spread naturally, we can achieve herd immunity.
    Fact: The idea behind herd immunity is to abandon all preventative measures to stop a pathogen and just let it infect susceptible people or “run its course.” The rationale is that a large portion of a community becomes immune, making person-to-person spread unlikely. However, most scientists and medical experts say herd immunity won’t work for COVID-19 as it would result in a catastrophic loss of human lives. Also, it isn’t known if a COVID-19 infection results in immunity to future infection and how long immunity lasts.
  3. Myth: You can get COVID-19 from vaccines.
    Fact: Several vaccines currently available in the U.S., but none of the vaccines use live SARS-CoV-2, the virus that causes COVID-19. Vaccines work by teaching our immune systems how to recognize and fight SARS-CoV-2. Sometimes a vaccine recipient can have symptoms, such as a fever, after receiving the vaccine. This is normal and shows the body is building immunity. The Pfizer and Moderna vaccines each take two doses, and the Johnson & Johnson vaccine requires one dose. After a vaccination is complete, it usually takes a few weeks to build immunity and provide protection. During that time, it is possible a person could be infected with the virus that causes COVID-19.
  4. Myth: If you’ve already been infected with COVID-19, you don’t need the vaccine.
    Fact: Those who have already been infected with COVID-19 may still benefit from the vaccine. Experts don’t know how long someone is protected from getting sick again after recovering from COVID-19. It is possible to be re-infected, and severe health risks are associated with COVID-19, so the CDC is advising those who have been sick with COVID-19 in the past should still get vaccinated. Anyone getting the vaccine must be symptom-free and out of quarantine. Those treated with monoclonal antibodies or convalescent plasma during a COVID-19 infection should wait 90 days before vaccination.
