I’m not going to beat around the bush much here: The situation in parts of Europe, including Austria, is dramatic. Due to the high incidence situation, I advise everyone who can to get a booster dose.
All those who have received the AstraZeneca or Johnson & Johnson vaccine should get boostered as soon as possible; all those who have received mRNA after 5-6 months (earlier makes no sense).
The vaccination you have already received still protects against severe disease and I am not worried about you.
However, the booster dose dramatically reduces the risk of asymptomatic or mild breakthrough infection. This also reduces the risk of passing the virus to unvaccinated (children, grandchildren) and probably saves trouble and problems with breakthrough infections. The full protection of the booster vaccination occurs within 7-10 days, so quite quickly.
People who have already had a breakthrough infection do not need a booster! The breakthrough infection has the same effect.
I have not yet had a third vaccination (but could for some time) because the incidence in New York is low. However, I will get boostered on November 22, so that I can come to Austria with optimal protection.
Stay healthy and reduce contacts. If you really haven’t been vaccinated yet, go get vaccinated.
