Existing COVID-19 vaccines offer strong protection against hospitalization, serious illness and death.
However, they are not 100% effective against preventing COVID-19 infection. These cases are called “breakthrough infections” where fully vaccinated people, in most cases, develop a milder form of the virus.
Here’s what you need to know.
According to the ZOE COVID Symptom Study, the top five symptoms of a breakthrough case are:
- Headache
- Runny nose
- sneezing
- Sore throat
- Loss of sense of smell
Medical experts say it’s not unusual for a person to experience breakthrough COVID-19 symptoms for several weeks, but at the same time, the worst symptoms such as a headache or cough could go away in two. weeks or less, according to Roll Call.
The CDC says people vaccinated and tested positive must quarantine or isolate for 10 days. Once these 10 days have passed, the person is no longer contagious provided they have not been seriously ill, have not had a fever for at least 24 hours and the remaining symptoms improve. (not counting the loss of smell and taste).
According to NPR, a small Israeli study found that breakthrough infections may contribute to long symptoms of COVID.
The study followed 1,500 fully immunized health workers. Of those, 39 contracted a breakthrough infection and seven reported long symptoms of COVID that lasted more than six weeks, according to the study.
So yes, you can be at risk for COVID for a long time if you catch a breakthrough infection. But this is rare for a person who is fully vaccinated.
