Third Shot vaccination for COVID-19 in Israel

After several manufacturers announced COVID-19 vaccine efficacy in clinical trials for disease, a comprehensive post-efficacy strategy for the following steps to ensure vaccination of the global population is now required. These considerations should include: how to manufacture billions of doses of high-quality vaccines, support for vaccine purchase, coordination of supply, the equitable distribution of vaccines, and the logistics of global vaccine delivery, all of which are a prelude to a massive vaccination campaign targeting people of all ages. Furthermore, additional scientific questions about the vaccines remain, and that should be answered to improve vaccine efficacy, including questions regarding the optimization of vaccination regimens, booster doses, the correlates of protection, vaccine effectiveness, safety, and enhanced surveillance. The timely and coordinated execution of these post-efficacy tasks will bring the pandemic effective and efficient [1].
