Adverse effects of COVID‑19 vaccines
and measures to prevent them
Kenji Yamamoto*
Recently, The Lancet published a study on the effectiveness of COVID-19 vaccines and the waning of immunity with
time.
The study showed that immune function among vaccinated individuals 8 months after the administration of
two doses of COVID-19 vaccine was lower than that among the unvaccinated individuals. According to European
Medicines Agency recommendations,
frequent COVID-19 booster shots could adversely affect the immune response
and may not be feasible. The decrease in immunity can be caused by several factors such as N1-methylpseudouridine,
the spike protein, lipid nanoparticles, antibody-dependent enhancement, and the original antigenic stimulus.
These clinical alterations may explain the association reported between COVID-19 vaccination and shingles. As a
safety measure, further booster vaccinations should be discontinued. In addition, the date of vaccination should be
recorded in the medical record of patients.
