12 August 2021 - On July 8, 2021, Pfizer and BioNTech announced they would be seeking US and European authorisation for administration of a third booster dose of their COVID-19 vaccine.
The same day, the US FDA and the Centers for Disease Control and Prevention emphasised that current evidence does not suggest a need for this booster dose.
Other countries, such as Israel, the UK, France, Germany, Sweden, and the UAE are not waiting for further evidence of the efficacy of booster vaccination and will imminently begin offering boosters to large segments of their populations.
