Risk of second allergic reaction to SARS-CoV-2 vaccines: a systematic review and meta-analysis.
The purpose of this systematic review and meta-analysis of case studies and case reports was to assess the risk of severe immediate allergic reactions to a second dose of SARS-CoV-2 mRNA vaccine in people who experienced an immediate allergic reaction to the first dose. The researchers evaluated the World Health Organization Global Coronavirus database, Web of Science, MEDLINE, and Embase from the date of inception through October 4th, 2021. The main outcomes and measures were a risk of severe immediate allergic reaction and repeated severe immediate allergic reactions with a second vaccine dose. The study found that among 22 studies of SARS-CoV-2 mRNA vaccines, 1366 individuals had immediate allergic reactions to their first vaccination. Of these, 87.8% were women with a mean age of 46.1 years. Six patients developed severe immediate allergic reactions after their second vaccination, 232 developed mild symptoms, and 1360 tolerated the dose. Among 78 persons with severe immediate allergic reactions to their first SARS-CoV-2 mRNA vaccination, 4 people had a second severe immediate reaction, and 15 had non-severe symptoms. There were no deaths. The study concluded that in a supervised setting equipped to manage severe allergic reactions, revaccination of individuals with an immediate allergic reaction to a first SARS-CoV-2 mRNA vaccine dose can be safe.

A risk prediction model to identify newborns at risk for missing early childhood vaccinations.
Approximately 30% of US children aged 24 months have not received all recommended vaccines. This retrospective cohort study aimed to develop a prediction model to identify newborns at high risk for missing early childhood vaccines. The investigators concluded that their prediction model using information readily available in birth hospitalization records consistently identified newborns at high risk for undervaccination.

Mining social media data to assess the risk of skin and soft tissue infections from allergen immunotherapy.
This study examined large social media databases including Facebook, Twitter, and Reddit to identify postings of rare incidents of contamination or infection from extracts for allergen immunotherapy (AIT). They used natural language processing (NLP) related to AIT from 2012 to 2016. They compared posts on adverse events for AIT compared to influenza vaccinations. The results showed that both types of posts are rare events.

Risk of herpes zoster in autoimmune and inflammatory diseases: implications for vaccination.
This study was undertaken to evaluate the age-stratified incidence of herpes zoster (HZ) in patients with autoimmune or inflammatory (AI) diseases as compared to older adults for whom the HZ vaccine is currently recommended by the US Centers for Disease Control and Prevention. The researchers found that systemic lupus erythematosus, inflammatory bowel disease, and rheumatoid arthritis are AI diseases associated with a higher risk of HZ compared to that in older adults for whom vaccination is currently recommended, suggesting that individuals with these conditions who are as young as age 40 years could potentially benefit from the HZ vaccine.
