Researchers at Tel Aviv University equip close to 5,000 Israelis with smartwatches and monitor their physiological parameters over two years. After monitor, 2,038 receive the booster dose of the COVID-19 vaccine, allowing the researchers to objectively compare measures before and after the participants took the vaccine, and confirm the safety of the vaccine.
The Researchers team also examin the safety of the booster by analysing the medical files of 2,50,000 members of Maccabi Health Services anonymously.
Researchers were able to evaluate safety of the vaccines from three perspectives: subjectively :
What the participant reports, objectively,
What the watch detects, and clinically,
What the doctor diagnoses.
Professor Dan Yamin from Tel Aviv University Said :
Researchers said the most surprising finding was that the watches were more sensitive than the people they were monitoring.
Many participants report for fatigue, headache, etc. after receiving the vaccine, and after two or three days report that they felt normal and well, they said.
Dan Yamin Said :
In the medical literature, 25 unusual side effects attribute to the COVID vaccine were report, and the researchers paid special attention to look for rare cases of inflammation of the heart muscle (myocarditis) and pericarditis.
