A study showed that people who experienced symptoms such as chills, fatigue, and headaches after receiving the coronavirus vaccine had more antibodies. What was thought to be side effects after vaccination are only temporary symptoms that occur during the antibody production process.
A research team at the University of California, San Francisco (UCSF) found that people who experienced side effects after receiving the coronavirus vaccine had antibodies that were nearly twice as high as those who did not experience side effects. Symptoms such as chills and headaches that occurred after vaccination were signs of a strong immune response. The research team said, “Symptoms that occur after vaccination may be unpleasant, but they actually disprove the effectiveness of the vaccine,” and added, “We hope that this study will alleviate concerns about symptoms that appear after vaccination.”
The research team recruited 363 adults who received the primary dose of Pfizer or Moderna’s mRNA vaccine immediately after the coronavirus vaccine was released in December 2020. Among the study participants, those who had symptoms of coronavirus infection were excluded. The research team measured the participants’ vital signs, such as body temperature, breathing, and heart rate, after receiving the mRNA vaccine. Symptoms after vaccination were monitored daily for 6 days after vaccination, and antibody levels were measured 1 month and 6 months after vaccination.
As a result of the study, study participants who experienced seven symptoms, including chills, fatigue, and headaches after vaccination, had antibody levels that were 140-160% higher than those who had no symptoms. Additionally, even if body temperature rose by just 1 degree after vaccination, antibody levels were found to increase more than three times six months after the second vaccination. Experts believe that although research was conducted focusing on the Wuhan variant of the virus in the early stages of the coronavirus epidemic, the same can be applied to the currently prevalent XBB variant.
The research team said, “The lack of a vaccine response does not mean that the vaccine is ineffective,” and “98% of people who did not experience a vaccine response also produced a large amount of antibodies.”
