ABSTRACT
During the COVID-19 pandemic, postexposure-vaccine-prophylaxis is not a practice. Following exposure, only patient isolation is imposed. Moreover, no therapeutic prevention approach is applied. We asked whether evidence exists for reduced mortality rate following postexposure-vaccine-prophylaxis. To estimate the effectiveness of postexposure-vaccine-prophylaxis, we obtained data from the Israeli Ministry of Health registry. The study population consisted of Israeli residents aged 12 years and older, identified for the first time as PCR-positive for SARS-CoV-2, between December 20th, 2020 (the beginning of the vaccination campaign) and October 7th, 2021. We compared "recently injected" patients-that proved PCR-positive on the same day or on 1 of the 5 consecutive days after first vaccination (representing an unintended postexposure-vaccine-prophylaxis)s-to unvaccinated control group. Among Israeli residents identified PCR-positive for SARS-CoV-2, 11 687 were found positive on the day they received their first vaccine injection (BNT162b2) or on 1 of the 5 days thereafter. In patients over 65 years, 143 deaths occurred among 1412 recently injected (10.13%) compared to 255 deaths among the 1412 unvaccinated (18.06%), odd ratio (OR) 0.51 (95% confidence interval [CI]: 0.41-0.64; p < 0.001). A significant reduction in the death toll was observed among the 55-64 age group, with 8 deaths occurring among the 1320 recently injected (0.61%) compared to 24 deaths among the 1320 unvaccinated control (1.82%), OR 0.33 (95% CI: 0.13-0.76; p = 0.007). Postexposure-vaccine-prophylaxis is effective against death in COVID-19 infection.
ABSTRACT
Introduction: To prevent rabies in animal bite victims, complete postexposure prophylaxis (PEP) with an anti-rabies vaccination (ARV) is essential. This study was done to determine the compliance rate of ARV in patients with animal bites who presented to the emergency department (ED) during the COVID-19 pandemic. Materials and Methods: This was a prospective observational study done on patients presenting to the ED with a history of animal bites over 1 year (May 2020-June 2021). Categorical variables were presented as percentages, and quantitative variables were summarized using mean and standard deviation (SD). Results: A total of 122 animal bite (World Health Organization [WHO] Category II and III) victims presented to the ED during the study. The mean age of the cohort was 38.12 (SD: 16.4) years with a male (n = 67: 54.9%) preponderance. Based on the physiological stability, a majority were triaged as priority III (n = 119;97.5%). Most patients presented with dog bites (n = 88;72.1%), followed by cat (n = 14;11.5%) and rat bites (n = 13;10.7%). Two-thirds were unprovoked (n = 82;67.2%) and were caused by stray animals (n = 62;50.8%). More than half (n = 65;53.3%) of the bites were WHO Category III bites. All Category II and III patients had received the first dose of ARV at our center and category III patients received immunoglobulin local injection as well. Noncompliance to ARV was seen in almost a quarter (n = 32;26.2%) of patients of which forgotten dates (n = 11;34.4%) were the most common cause. There was no significant statistical variable to determine the cause of noncompliance. Conclusion: Unprovoked bites by stray dogs were the cause of a majority of the animal bites. Compliance with PEP remains low at two-thirds of the total. The most common cause of noncompliance to ARV was due to forgotten dates.

ABSTRACT
BACKGROUND: Safe and effective hepatitis A vaccines have been recommended in the United States for at-risk adults since 1996; however, adult vaccination coverage is low. METHODS: Among a random sample of adult outbreak-associated hepatitis A cases from three states that were heavily affected by person-to-person hepatitis A outbreaks, we assessed the presence of documented Advisory Committee on Immunization Practices (ACIP) indications for hepatitis A vaccination, hepatitis A vaccination status, and whether cases that were epidemiologically linked to an outbreak-associated hepatitis A case had received postexposure prophylaxis (PEP). RESULTS: Overall, 74.1% of cases had a documented ACIP indication for hepatitis A vaccination. Fewer than 20% of epidemiologically linked cases received PEP. CONCLUSIONS: Efforts are needed to increase provider awareness of and adherence to ACIP childhood and adult hepatitis A vaccination and PEP recommendations in order to stop the current person-to-person hepatitis A outbreaks and prevent similar outbreaks in the future.
