COVID-19: Vaccine hesitant in the USA unlikely to change their minds

このほど実施された全国代表調査において、重症急性呼吸器症候群コロナウイルス2 (SARS-CoV-2)ワクチンの接種を望まない米国人の半数は、何があってもワクチン接種を受けたくない気持ちが変わることはないと回答したことを報告する論文が、Scientific Reportsに掲載される。

今回、Jeffrey Lazarusたちの研究チームは、2021年4月に、米国の成人6037人を対象としてSARS-CoV-2ワクチンの接種に対する態度を調査した。調査参加者の3分の2はニューヨーク、ロサンゼルス、ダラス、シカゴの住民が占め、残りの3分の1は、それ以外の米国各地の住民だった。



Half of those in the USA who are unwilling to be vaccinated against SARS-CoV-2 report that nothing will change their mind, according to a representative national survey reported in a study published in Scientific Reports.

Jeffrey Lazarus and colleagues surveyed 6,037 American adults in April 2021 to identify their attitudes towards vaccination against SARS-CoV-2. One third of the participants came from across the USA and two thirds were from New York, Los Angeles, Dallas or Chicago.

The authors found that 21.4% of participants from across the USA were unwilling to be vaccinated against SARS-CoV-2, compared to 19.7% in Dallas, 11.5% in Los Angeles, 11.2% in Chicago and 10.1% in New York. Of those unwilling to be vaccinated, half stated that nothing would convince them to receive the vaccine and the majority reported that their unwillingness was caused by concerns about vaccine safety. Unwillingness to be vaccinated tended to be higher among those who worked outside of the home, held conservative political views, had a lower household income and had not previously tested positive for COVID-19. Education levels, race, age and sex were not uniformly associated with unwillingness to be vaccinated. Although over 82% of participants agreed that COVID-19 is a dangerous health threat, over 18% did not believe that the dangers of COVID-19 exceeded those of the vaccine and over 15% did not believe that COVID-19 can be prevented by vaccination. Over 50% of participants were in favour of the government requiring vaccination against SARS-CoV-2 and over 68% supported vaccination requirements for international travel.

The findings suggest that, while vaccination mandates are likely to be broadly accepted, additional, targeted interventions are needed to increase SARS-CoV-2 vaccine uptake among those with conservative political views and low household income.
