Booster jabs意思

"Booster jabs" is a term used to refer to additional doses of a vaccine administered to individuals who have already received the standard course of vaccination. These booster shots are given to enhance or renew the protection provided by the initial vaccinations, as the effectiveness of vaccines can wane over time.

The concept of booster jabs is not new; many vaccines, such as those for tetanus, diphtheria, and pertussis (whooping cough), include a schedule of booster doses to ensure ongoing immunity. With the introduction of COVID-19 vaccines, the term has become more widely used as public health authorities and governments discuss the need for booster shots to maintain immunity against the SARS-CoV-2 virus and its variants.

The specific timing, eligibility criteria, and types of vaccines used for booster jabs can vary depending on the country, the vaccine being administered, and the latest recommendations from health authorities. For example, some countries have started offering booster doses to certain populations, such as the elderly or those with compromised immune systems, to protect against severe COVID-19 disease.

It's important to follow the guidance provided by local health authorities and consult with healthcare professionals to determine if and when a booster jab is recommended for an individual.
