It has been just revealed that the people who are at greater risk for COVID-19 vaccine side effects are females and young adults. Check out the latest reports about this below.
Risks of COVID vaccines
According to a Japanese study published in November on Scientific Reports, females and young adults may have a higher risk of experiencing side effects after receiving COVID-19 vaccinations. Additionally, the study found that people who receive three doses instead of two may experience different side effects.
The study involved 272 hospital employees who received the Pfizer vaccine as their second dose between January and June 2022.
None of the participants had a previous history of COVID-19 infection, and their symptoms were examined and diagnosed by doctors at the hospital.
They found “higher frequencies of COVID-19 vaccine-related side effects” and “worse outcomes with longer recovery from side effects” among females and younger adults compared to males and elderly adults, the authors wrote.
The study conducted by the authors revealed that different dosages of the vaccine were associated with different side effects.
Furthermore, the side effects experienced after the third dose were found to be more severe and long-lasting compared to those occurring after the second dose.
In particular, axillary pain was found to be much more common in people who received three doses as opposed to two.
Headaches and joint pain were also reported to be more prolonged after the third dose compared to the first or second dose.
Common symptoms experienced after the second dose include asthma symptoms, ear fullness, numbness in the upper arm, and injection site discomfort. The authors of the study linked these symptoms to an allergic response.
On the other hand, headaches and joint pains after the third dose were associated with inflammation and immune dysregulation.
Studies and doctors have reported that patients who report post-vaccination symptoms share similar demographics.
The 2022 post-vaccine survey by REACT19 revealed that females between the ages of 30 to 50 are at a higher risk of experiencing symptoms after vaccination.
Dr. Keith Berkowitz, an internist who has treated over 200 patients with long COVID and post-vaccine symptoms, suggests that additional vaccines can have a cumulative effect, meaning that people who have taken more shots are at a greater risk of experiencing worse symptoms.
