IMPORTANCE

Herpes zoster infection after COVID-19 vaccination has been reported in numerous case studies. It is not known whether these cases represent increased reporting or a true increase in risk.

OBJECTIVE

To assess whether COVID-19 vaccination is associated with an increased risk of herpes zoster infection.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used a self-controlled risk interval (SCRI) design to compare the risk of herpes zoster in a risk interval of 30 days after COVID-19 vaccination or up to the date of the second vaccine dose with a control interval remote from COVID-19 vaccination (defined as 60-90 days after the last recorded vaccination date for each individual, allowing for a 30-day washout period between control and risk intervals). A supplemental cohort analysis was used to compare the risk of herpes zoster after COVID-19 vaccination with the risk of herpes zoster after influenza vaccination among 2 historical cohorts who received an influenza vaccine in the prepandemic period (January 1, 2018, to December 31, 2019) or the early pandemic period (March 1, 2020, to November 30, 2020). Data were obtained from Optum Labs Data Warehouse, a US national deidentified claims-based database. A total of 2 039 854 individuals who received any dose of a COVID-19 vaccine with emergency use authorization (BNT162b2 [Pfizer-BioNTech], mRNA-1273 [Moderna], or Ad26.COV2.S [Johnson & Johnson]) from December 11, 2020, through June 30, 2021, were eligible for inclusion. Individuals included in the SCRI analysis were a subset of the COVID-19-vaccinated cohort who had herpes zoster during either a risk or control interval.

EXPOSURES

Any dose of a COVID-19 vaccine.

MAIN OUTCOMES AND MEASURES

Incident herpes zoster, defined by International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes and a prescription of a new antiviral medication or a dose increase in antiviral medication within 5 days of diagnosis.

RESULTS

Among 2 039 854 individuals who received any dose of a COVID-19 vaccine during the study period, the mean (SD) age was 43.2 (16.3) years; 1 031 149 individuals (50.6%) were female, and 1 344 318 (65.9%) were White. Of those, 1451 patients (mean [SD] age, 51.6 [12.6] years; 845 [58.2%] female) with a herpes zoster diagnosis were included in the primary SCRI analysis. In the SCRI analysis, COVID-19 vaccination was not associated with an increased risk of herpes zoster after adjustment (incidence rate ratio, 0.91; 95% CI, 0.82-1.01; P = .08). In the supplementary cohort analysis, COVID-19 vaccination was not associated with a higher risk of herpes zoster compared with influenza vaccination in the prepandemic period (first dose of COVID-19 vaccine: hazard ratio [HR], 0.78 [95% CI, 0.70-0.86; P < .001]; second dose of COVID-19 vaccine: HR, 0.79 [95% CI, 0.71-0.88; P < .001]) or the early pandemic period (first dose of COVID-19 vaccine: HR, 0.89 [95% CI, 0.80-1.00; P = .05]; second dose: HR, 0.91 [95% CI, 0.81-1.02; P = .09]).

CONCLUSIONS AND RELEVANCE

In this study, there was no association found between COVID-19 vaccination and an increased risk of herpes zoster infection, which may help to address concerns about the safety profile of the COVID-19 vaccines among patients and clinicians.

OBJECTIVES

In the setting of a 50% increase in opioid overdose deaths, the coronavirus disease 2019 crisis opened housing opportunities in the form of Shelter in Place (SIP) hotels to homeless San Francisco residents. Many who entered SIP hotels had opioid use disorder. In fall 2020, Community Behavioral Health Services Pharmacy partnered with SIP hotel medical staff to launch a pilot project, where on-site SIP medical providers prescribed buprenor-phine (BUP) and clinical pharmacists hand-delivered BUP to SIP residents to increase BUP initiation and engagement.

METHODS

A retrospective chart review of 3 patients living in SIP hotels starting BUP to demonstrate the feasibility of a SIP hotel BUP delivery program.

RESULTS

In all 3 cases, patients were able to start and continue BUP with on-site medical staff visits and delivery of medications by pharmacists. Each case highlights different barriers that were overcome by this system.

CONCLUSIONS

Our findings suggest that this system of onsite medical care with pharmacist delivery is possible and has the potential to allow for greater outreach and increased ease of obtaining medications for patients.
