Vaccination programs against COVID-19 have been implemented all over the world since December 2020. Beside the common side effects of vaccines, there are also increasing reports of herpes zoster (HZ) activation. In this report, we describe three cases of HZ, one of them with post-herpetic neuralgia (PHN) after receiving inactivated COVID-19 vaccine. The first two patients developed HZ 8 and 10 days after vaccination, respectively. When pain could not be controlled with paracetamol and non-steroidal anti-inflammatories, the patients received weak opioid codeine. In addition, the first patient received gabapentin, and the second patient was applied erector spinae plane block. The third patient was admitted 4 months after the diagnosis of HZ and considered to have PHN and pain palliation was provided with tramadol. Although the exact cause has not yet been fully resolved, increased reports of HZ after vaccination suggests a link between vaccines and HZ. Considering that receiving COVID-19 vaccines will going on, HZ and PHN cases will continue to be seen. More epidemiological studies are needed to further evaluate the relationship between COVID-19 vaccines and HZ.

Due to COVID-19, vaccinations dropped in 2020 and 2021. We estimated the impact of reduced recombinant zoster vaccine (RZV) use on herpes zoster (HZ) cases, complications, and quality-adjusted life-year (QALY) losses among older adults. Various scenarios were compared with Markov models using data from national sources, clinical trials, and literature. Missed series initiations were calculated based on RZV distributed doses. In 2020, 3.9 million RZV series initiations were missed, resulting in 31,945 HZ cases, 2,714 postherpetic neuralgia cases, and 610 lost QALYs. Scenarios further projected disease burden increases if individuals remain unvaccinated in 2021 or the same number of initiations are missed in 2021. Health professionals should emphasize the importance of vaccination against all preventable diseases during the COVID-19 era.
