Approximately 5.1 million Israelis had been fully immunized against coronavirus disease 2019 (Covid-19) after receiving two doses of the BNT162b2 messenger RNA vaccine (Pfizer–BioNTech) by May 31, 2021. After early reports of myocarditis during adverse events monitoring, the Israeli Ministry of Health initiated active surveillance. We retrospectively reviewed data obtained from December 20, 2020, to May 31, 2021, regarding all cases of myocarditis and categorized the information using the Brighton Collaboration definition. We analyzed the occurrence of myocarditis by computing the risk difference for the comparison of the incidence after the first and second vaccine doses (21 days apart); by calculating the standardized incidence ratio of the observed-to-expected incidence within 21 days after the first dose and 30 days after the second dose, independent of certainty of diagnosis; and by calculating the rate ratio 30 days after the second dose as compared with unvaccinated persons. Among 304 persons with symptoms of myocarditis, 21 had received an alternative diagnosis. Of the remaining 283 cases, 142 occurred after receipt of the BNT162b2 vaccine; of these cases, 136 diagnoses were definitive or probable. The clinical presentation was judged to be mild in 129 recipients (95%); one fulminant case was fatal. The overall risk difference between the first and second doses was 1.76 per 100,000 persons (95% confidence interval [CI], 1.33 to 2.19), with the largest difference among male recipients between the ages of 16 and 19 years (difference, 13.73 per 100,000 persons; 95% CI, 8.11 to 19.46). As compared with the expected incidence based on historical data, the standardized incidence ratio was 5.34 (95% CI, 4.48 to 6.40) and was highest after the second dose in male recipients between the ages of 16 and 19 years (13.60; 95% CI, 9.30 to 19.20). The rate ratio 30 days after the second vaccine dose in fully vaccinated recipients, as compared with unvaccinated persons, was 2.35 (95% CI, 1.10 to 5.02); the rate ratio was again highest in male recipients between the ages of 16 and 19 years (8.96; 95% CI, 4.50 to 17.83), with a ratio of 1 in 6637. The incidence of myocarditis, although low, increased after the receipt of the BNT162b2 vaccine, particularly after the second dose among young male recipients. The clinical presentation of myocarditis after vaccination was usually mild.

Using an active nationwide surveillance system administered by the Israeli Ministry of Health, we previously found a higher incidence of myocarditis among persons 16 years of age or older who had received the BNT162b2 vaccine (Pfizer–BioNTech) than among historical controls and unvaccinated persons; the incidence was highest among young male recipients.1 The Food and Drug Administration recently granted emergency use authorization for the two-dose regimen of the BNT162b2 vaccine in adolescents 12 to 15 years of age. Here, we report the incidence of hospitalization for myocarditis between June 2 and October 20, 2021, among adolescents in this age group within 21 days after receipt of the first vaccine dose and within 30 days after receipt of the second dose.

Front-of-package labels (FOPL) are designed to simplify nutrition information and to help consumers make healthier food choices. The Israeli government has implemented new regulations requiring mandatory red warning FOPL for high levels of sodium, sugar, or saturated fats. A voluntary green positive FOPL for products fitting the national nutritional recommendations was concurrently encouraged. In order to characterise adult consumers' current use of Nutrition Facts Tables (NFT) and their attitudes towards the new FOPL, a nationally representative cross-sectional telephone survey was conducted. Most of the 1,042 survey respondents reported frequent NFT use (76.2%) and intentions to purchase fewer red-labelled (81.1%) and more green-labelled products (85.0%). Consumers with higher BMI and lower education expressed higher intentions to use the new FOPL, but not higher current use of NFT. This finding suggests that these high-risk groups, which the new labels are meant to target, may indeed benefit from the new policy.

Evidence on the association between dialysis facility accessibility and mortality in small countries is limited. This study evaluated the association between travel distance and one- and two-year mortality among Israeli end-stage renal disease (ESRD) patients. Data were obtained from the National Renal Replacement Therapy Registry, encompassing all Israeli ESRD patients aged ≥ 45 years who initiated hemodialysis in 2010–2021. Sociodemographic (age, sex, population group), treatment-related (hospital/community treatment, primary renal disease, incident-year cohort), and geographic (residency socioeconomic and peripherality indices) data were collected. Travel distances from the most recent address to the initial treating facility were categorized into three groups based on the 50th and 90th percentiles, excluding outliers (> 100 km). Adjusted Cox regressions assessed associations between travel distances and mortality, with incident-year cohort-specific models evaluating temporal hazard variations. Analyses included 15,606 patients. The long-distance group (> 26.39 km) was characterized by younger age, Arab ethnicity, peripheral residence, and lower socioeconomic status. Compared to the short-distance group (≤ 6.80 km), the hazard ratios (HRs) in the intermediate-distance group (> 6.80 and ≤ 26.39 km) were 1.216 (1.106–1.337) for one-year and 1.181 (1.093–1.275) for two-year mortality. In the long-distance group, the HRs were 1.718 (1.460–2.021) for one-year and 1.554 (1.351–1.787) for two-year mortality ( P-for-trend between travel distances <.001). Sensitivity and temporal analyses confirmed consistent associations across incident-year cohorts, alternative cut-offs, and outlier inclusion. The association between travel distance and mortality highlights the need to improve geographic accessibility to healthcare to reduce inequities, especially for life-sustaining chronic treatments such as hemodialysis.
