In fact, there is a chance that you could have been infected with coronavirus and even even knowledge.

In fact, new research has found that a particular vaccine reaction could indicate that you have already had Covid.

Researchers of the Translational Institute of Search Scripps in Californiareported on physiological responses For COVID vaccines, publishing an early version of their study 4 May on Medrxiv. Researchers collected data from more than 4,000 Americans using smartphone-based application that reports physiological activities from Smartwatches and found that some people undergo an increase in cardiac rhythm as a vaccine reaction. According to the study, the researchers found that the resting heart rate of some people increased up to 1.5 additional beat per minute (BPM) after receiving a dose of the Pfizer or the Moderna vaccine.

The researchers found that those who had already been infected with COVID had higher heart rates than those who had not been infected. However, it was only the case of the first dose. According to the study, people who had previously been infected had an increase in heart rate of more than 1.5 minute after the first dose between the first and fifth day after vaccination. However, those that had not been previously infected have experienced only one increase of less than 0.5 BPM in the same period after the first dose. For the second dose, those previously infected and those who did not have Covid saw an increase of more than 1.5 BPMs between the first and fifth day after vaccination.

"We have identified a rapid increase in heart rate the day after vaccination and a person who was more robust after the second dose, unless the participant had an earlier CVIV-19 infection," said researchers. in the study.

Although this vaccine response has been reported among participants who have received both Pfizer and Moderna vaccines, researchers have found more important heart rate changes in those with modern to the two doses. According to the study, Moderna participants experienced an increase in cardiac frequency of more than 0.5 BPM after the first dose, while the recipients of Pfizer experienced increases of less than 0.5 BPMs. For the second dose, the two increases were higher, but Moderna participants experienced an average increase of more than 2 BPMs while Pfizer participants recorded an average increase of more than 1 BPM.

According to the study, most vaccinated people with Moderna and Pfizer have increased their heart rate at rest within two days of vaccination, with 70% after the first dose and 76% the test after the second. Researchers have found that heart rate changes peaked on the second day after vaccination, but have always lasted several days after that. For the first dose, the cardiac rates of the participants did not return to normal until the fourth day after taking over. And for the second dose of vaccine, their cardiac rates did not return to normal until the sixth day after fire.
