A survey conducted by public health experts in India revealed that side effects after vaccination against Covid-19 are more likely to occur in 66 per cent of health care workers, and may subside within a day of their onset.
The survey, which gathered the responses of 5,396 respondents, all of them healthcare professionals, who had received Covid vaccines, among all health care workers, nearly 66 percent of them reported at least post-vaccination symptoms, according to thehealthsite. .
Side effects after vaccination against Covid-19
According to the study, survey respondents reported that the most common symptoms they experienced after vaccination were muscle pain (44 percent), fever (34 percent), headache (28 percent), localized pain at the injection site (27 percent), Joint pain (12 percent), nausea (8 percent), and diarrhea (3 percent) while fatigue (45 percent), is the most common.
Other symptoms such as sore throat, insomnia, severe dizziness, allergic rash, chills, vomiting, and fainting were reported of 1 percent or less.
The study also noted that the symptoms reported by the respondents were not severe in nature or required hospitalization. Besides, the survey indicated that in 90 percent of cases, symptoms were either milder than expected or met the expectations of the vaccine recipient.
Meanwhile, the research showed that the side effects in most of the respondents did not persist 24 hours after their onset, as 37 percent (1225) of the respondents revealed that their symptoms did not last longer than a day, while 31 percent showed that their symptoms lasted for 48 hours, Only 6 percent claimed that their symptoms extended beyond 48 hours.
Vaccines are safe
According to Dr Rajiv Jayadvan, former president of the Indian Medical Association, one of the researchers of the survey, one of the key points from the survey is that vaccines are safe and there is no need to fear that they will be harmful.
He reiterated that if more than 5,000 people had been vaccinated, and had not reported any serious problem, this was a major confirmation that the general public could get the vaccine.
The other main finding of the survey is the association between age and post-vaccination symptoms, which indicates that the vaccine reaction decreases with age; This means the chance that symptoms will decrease with age.
Which group experienced the most side effects?
The highest rate of symptom recurrence, 81.34%, was found in respondents aged 20-29 years, followed by 30-39 years (79.57%), 40-49 years (67.94%), 50-59 years (58.23). Percent), 60-69 years old (44.76 percent), 70-79 years old (33.73 percent), 80-89 years old (7.43 percent).
Jayadavan said that young people produce a lot of inflammatory cytokines that trigger a reactivity (symptoms from the average person’s perspective) and that is why they have a strong response to vaccines, while there is less in the elderly, however, he added that the reaction is not a reliable marker of antibody production.
Everyone responds differently to vaccines
“There is a misconception among people and even healthcare professionals who believe that the reaction is related to the development of antibodies. Each person responds differently to vaccines and raises different levels of reaction according to age and other influencing factors. It cannot be considered a marker to determine that the body is producing an immune response.” For vaccines.
