Vaccinated twice against COVID-19, and that was supposed to be it. Now, according to expert recommendations, one should get another booster shot. Why this isn't a new concept and is common practice for many vaccinations will be briefly examined.

Boosters are recommended for most vaccines to maintain protection. For some vaccines, this happens sooner, like with the annual flu shot, while for others, it occurs later, such as tetanus, which only needs a booster every ten years. In Austria, it is currently recommended to administer a COVID-19 booster shot six months after the initial vaccination. For individuals vaccinated with AstraZeneca or Johnson & Johnson, a booster is recommended after four months. The purpose of these booster shots is to further strengthen the immune system and reduce the risk of infection. They play a crucial role in maintaining the vaccine's effectiveness and contribute to both individual and collective immunity against COVID-19. Moreover, vaccines are continually evolving, which is necessary as the virus also mutates and new variants constantly emerge.

And while we’re on the topic of booster shots, be sure to get a flu vaccine this year alongside the COVID-19 vaccination. The flu shot is another worthwhile investment in a strong immune system and offers numerous health benefits.
