There’s a simple COVID-19 symptom that indicates whether or not someone might have had the novel coronavirus despite being fully vaccinated — sneezing.

Is sneezing a COVID-19 symptom?

Researchers with the ZOE COVID Symptom Study have been researching various systems for those who have been fully vaccinated and those who have not. They found that sneezing is a common symptom among those who got COVID-19 and had been fully vaccinated.

  • “Our data shows that people who had been vaccinated and then tested positive for COVID-19 were more likely to report sneezing as a symptom compared with those without a jab,” researchers wrote, according to The Hill.

However, the researchers said, “it’s important to remember that the link between sneezing and COVID-19 isn’t very strong, so you should stay alert to the 20 symptoms of the disease, whether or not you’ve been vaccinated.”

  • In fact, researchers said sneezing is often a sign of a common cold rather than COVID-19. But if sneezing is coming out of the blue, you might want to get a COVID-19 test to make sure you’re not carrying around the infectious disease.
  • “If you’ve been vaccinated and start sneezing a lot without an explanation, you should definitely get a COVID test, especially if you are living or working around people who are at greater risk from the disease,” researchers wrote.

What are COVID-19 symptoms for vaccinated people?

As I wrote for the Deseret News, the Zoe COVID Symptom study found that there are five symptoms you’re most likely to suffer from if you get COVID-19 after being fully vaccinated. Those symptoms include:

  • Headache
  • Runny nose
  • Sneezing
  • Sore throat
  • Other (loss of smell, shortness of breath, fever, persistent cough)

The same study said fully vaccinated people who are infected with the delta variant may feel like they had a bad cold. Unvaccinated people will suffer the normal COVID-19 symptoms — if not worse — from the delta variant.
