It is said that at least 70% of people should receive vaccination to achieve herd immunity. We conducted an online questionnaire survey on risk perception and attitude formation of Covid-19 vaccine with total of 2,500 respondents in 5 areas of Japan, Hokkaido, Tohoku, Tokyo, Osaka, and Chugoku-Shikoku from 11 to 15 December, 2020. The results showed that about half of respondents would accept inoculation with the vaccine. Only about 30% perceived that the vaccine would have good effects as medicine, and about 30% were afraid that it would have any side-effects. We put the same questions about Covid-19 vaccine before and after questions about HPV vaccine and influenza vaccine and the answers were very stable. It seemed that people's attitudes to Covid-19 vaccine had already formed. The female and people in their 30s and 40s had relatively less positive perception of Covid-19 vaccine. Risk communication with correct information of the vaccine should be needed to achieve the herd immunity with it.}, pages = {137--150}, title = {2020年12月における新型コロナウイルスワクチンへの人々の認識と態度形成 : 2,500名を対象としたオンライン調査結果}, volume = {11}, year = {2021} }
