A new study has tried to find out whether the opposite is true: a lack of side effects is equivalent to a weaker immune response.
To do their findings, the researchers examined 206 staff members of the Walter Reed National Military Medical Center for antibodies to the coronavirus before and after receiving the Pfizer vaccine.
Antibodies are proteins produced within the body’s immune response to infection.

Volunteers were all healthy, not having a weakened immune system, and were not infected with COVID-19 at the time of registration.
The team also had volunteers complete a questionnaire about their vaccine-induced side effects after each dose, measuring 12 symptoms’ duration and severity on a scale of 0 (not at all) to 4 (a lot).
They then performed antibody tests 37 days on average after their second jab.
When comparing participants’ antibody findings to their symptom scores, the authors highlighted.
They further added that the duration of side effects after the first and second Pfizer shots also “revealed no association” with antibody response.
They concluded by saying:
The finding has two key implications, the researchers noted.

The research was published medRxiv on July 2 and is yet to be peer-reviewed.
