In recent months Israel has become the first country to implement booster doses of the COVID-19 vaccine to their vaccination certificates, and is requiring people to have had three doses of the vaccine to receive a vaccine pass for indoor venues, the so called “green pass”. Even though the country has had one of the highest vaccination rates in the world and has still seemingly not reached herd immunity, Israel is also considering a fourth jab moving forward. Meanwhile much of the world remains unvaccinated and variants of interest seem to keep cropping up beyond the current Beta, Gamma and Delta variants. are booster doses the way to go in the global fight against the pandemic?
