Allergies - immunity
[Guideline Summary] S3 guidelines on allergy prevention
Recommendations of the S3 guideline Allergy Prevention were revised to enable evidence-based and updated recommendations for preventing allergic diseases. They are for primary prevention of bronchial asthma, allergic rhinitis, food allergy and atopic eczema, applying to individuals at risk and those not at risk (unless explicitly stated otherwise. Below listed a brief summary.
[Consensus statements] COVID-19 vaccine allergy safety in Hong Kong
After accumulation of local and international experience on COVID-19 Vaccine Allergy Safety, the Hong Kong Institute of Allergy (HKIA) task force has reformed to update the Hong Kong consensus on COVID-19 Vaccine Allergy Safety.
[Literature library] Coronavirus Disease 2019 (COVID-19) mRNA-based vaccination and breastfeeding
This is the first study demonstrating the presence of anti-receptor-binding domain (RBD) antibodies in the faeces of breastfed newborns, whose mothers had received mRNA-based Coronavirus Disease 2019 (COVID-19) vaccines before or during lactation.
[Literature Library] Epitope-Specific Response of Human Milk sIgA in COVID-19 Recovered Women
This study analyzed the human milk samples from maternity patients who recovered from SARS-CoV-2 infection and found that N-protein secretory immunoglobulin A 1 (sIgA1) and sIgA2 responses were found induced in 100% and 33% of cases respectively. Overall, the authors concluded that such antibody immunological landscape may confer infants with a passive immunity against COVID-19.
[Guideline summary] Updated EAACI guideline on early life food allergy prevention
The European Academy of Allergy and Clinical Immunology (EAACI) has released an updated guideline in the prevention of food allergy in infants and young children.

Bioactive Nutrition - A focus on Osteopontin
In this, the latest in our series on bioactive nutrition, we discuss the role of the bioactive protein osteopontin. Osteopontin plays a role in several biological processes including immune function and is present in most tissues and bodily fluids, with the highest concentration found in milk.
