Respiratory medicine that used smartwatches to monitor heart rate. Nearly 5,000 Israelis were given smartwatches by Tel Aviv University researchers, who then tracked their physiological data over a two-year period.
2,038 of the people being watched received the COVID-19 booster dosage, enabling the researchers to impartially evaluate outcomes before and after the individuals received the vaccination and reaffirm the vaccine's safety.
The scientists also anonymously reviewed the medical records of 2,50,000 Maccabi Health Services subscribers to assess the booster's safety.
From three different viewpoints, they were able to assess the safety of the vaccines: subjectively based on what the participant says, objectively based on what the watch detects, and clinically based on what the doctor diagnoses.
According to Professor Dan Yamin of Tel Aviv University, "The smartwatches were used to track a range of indicators such as heart rate, change in heart activity, quality of sleep, number of daily steps done, and more."
"A return to the participant's baseline, or the pulse levels after vaccination returning to their pre-vaccination levels after six days, was one of the clear and significant changes we observed after the vaccine was administered, as evidenced by an increase in heart rate compared to the pulse rate measured before vaccination. Consequently, our research supports the vaccine's safety "said Yamin.
The most unexpected discovery, according to the researchers, was that the timepieces were more sensitive than the subjects they were watching. Following the vaccination, several participants complained of weariness, headaches, etc.; nevertheless, after two to three days, they indicated they felt normal and in good health.
Contrarily, Yamin noted, "by looking at their watches, we found distinct alterations in heart rate that persisted for many more days."
"Additionally, among the people who received the vaccination, some did not feel any adverse effects at all yet, according to data from their smartwatches, undoubtedly underwent physiological alterations. To put it another way, we discovered that the smartwatches were more responsive to shifts in mood than the individuals themselves, "Added he.
25 unique side effects associated with the COVID vaccination were recorded in the medical literature, and the researchers paid close attention to seek for uncommon occurrences of myocarditis and pericarditis.
A quarter of a million Maccabi members were examined for the prevalence of these unique side effects, and the researchers discovered no rise in significant events of any sort linked to vaccination.
