We continue (Ref. 1: Proc. Jpn. Acad. Ser. B 97, 22-49) to analyze the COVID-19 status. We concentrate on the following issues in this work:1. Effect of vaccination against the spreading of SARS-CoV-2.2. General landscape of the world situation concerning vaccinations.3. Some aspects of the new variants of SARS-CoV-2.Our findings include:1. With vaccinations, it is fair to say that we have entered a new phase in the fight against the virus SARS-CoV-2. We have analyzed some preliminary data to find how vaccinations can be effective against COVID-19 spreading. This analysis is based on, and is a continuation of, our first paper quoted in Ref. 1.2.

The strength (parameter β) of a new contagious variant can be estimated based on the initial data on the variant (Section 5).
