Eight COVID-19 vaccines are currently licensed in the Philippines. Severe vaccination reactions and anaphylactic events occur very rarely overall. However, in order to be able to react early, an interdisciplinary team has set up a concept for the different risk groups.
The data on the individual COVID-19 vaccines is constantly growing. In general, the current vaccines are considered to be well tolerated - always provided that appropriate precautions and recommendations are followed for the individual agents and patient groups.
With regard to undesirable side effects, a distinction is made between vaccination reactions (vaccine reactogenicity), which in most cases subside by themselves within a few hours to days, and allergic reactions, which sometimes require intensive medical treatment.
Allergic reactions are defined as follows:
In this context, the Philippine Society of Allergy, Asthma & Immunology (PSAAI) has established different recommendations for the individual risk groups in order to best avoid serious anaphylactic reactions. People with the following risk factors are classified as moderate-risk patients who should be vaccinated under increased emergency preparedness:
If at least one of the risk factors mentioned is present, it is recommended to consult an appropriate specialist in advance and to carry out the vaccination in a centre adequately prepared for intensive care emergencies.
If a severe anaphylactic reaction to one of the vaccines does occur, the PSAAI recommends the following course of action:
The emergency procedure for children and adolescents is the same as for adults, but with a reduced epinephrine dose according to body weight: 0.01 mg/kg/dose (1 mg/ml ampoule).
