According to the Centers for Disease Control and Prevention, COVID-19 vaccines are the best way to protect people from serious illnesses caused by the virus, as well as to prevent extended hospital stays and death.
However, no vaccine is 100% effective, and although rare, fully vaccinated people can contract the coronavirus. These cases, known as breakthrough infections, can cause COVID-like symptoms – or no symptoms at all.
The researchers behind the ZOE COVID Symptom Study found that the five most common symptoms reported by people vaccinated against the virus are:
Loss of sense of smell
The study, which examines symptoms of COVID-19 and tracks the spread of the virus, is the idea of doctors and scientists at Massachusetts General Hospital, Harvard TH Chan School of Public Health, King’s College London and Stanford University School of Medicine, according to its website.
The researchers also teamed up with health science company ZOE for the report.
The study found that those vaccinated had symptoms of COVID-19 similar to those reported by people who had or had not received the vaccine. However, those vaccinated had fewer symptoms within a shorter time frame, “suggesting that they fell less seriously ill and improved more quickly,” the researchers wrote.
The report also found that certain symptoms – including a persistent cough – were more likely to appear in people who had received only one dose of the two-shot Pfizer or Moderna vaccine or had not been vaccinated with the vaccine. all.
“Oddly enough, we noticed that people who had been vaccinated and then tested positive for COVID-19 were more likely to report sneezing as a symptom than those who had not received a vaccine,” the study authors wrote. “If you’ve been vaccinated and start sneezing a lot without an explanation, you should get tested for COVID. “
Sneezing is not among the COVID-19 symptoms noted by the CDC, but the updated list includes fever or chills, cough, fatigue, new loss of taste or smell, and pain throat. Symptoms usually appear two to 14 days after exposure, the public health agency said, and can be mild or severe.
Asymptomatic cases are also possible among those who are fully vaccinated, which means there is a small chance that they could pass the virus on to others.
Although breakthrough infections are rare, those vaccinated should always watch for possible symptoms of COVID-19, the CDC said.
