Gladstone Institutes discovers why COVID-19 omicron infection doesn't give you natural immunity against other variants like delta and alpha.
"People who are infected with omicron tend to get more upper respiratory disease. Nose, throat, more congestion in the upper air ways. People who had delta in previous infections had more systemic symptoms like fever, body aches," said Dr. Swartzberg.by UCSF researchers, the Chan Zuckerberg Biohub and the Latino Task Force found that the most common symptom during omicron were cough, followed by sore throat, congestion and very rarely loss of smell or taste.
"If you were boosted ironically you got more upper airway congestion like nose is stuffier. If you were boosted, you just had a couple of the mRNA jabs or if you weren't vaccinated at all you didn't get necessarily as much upper airway congestion, but you got more sick in terms of fever and bad body aches," said Dr. Swartzberg.
The Latino Task Force was key in gathering this data. They followed up with those who tested positive at their Mission test site and tracked their symptoms.
