US Adult Catholics Attitudes About Vaccination Mark M. Gray, PhD This report presents findings from a national survey of 1,050 self-identified Catholics from May 21 to June 4, 2021 regarding vaccine use during the pandemic. The survey was taken online and was available in English and Spanish. CARA programmed and hosted the online survey. The sample was provided by Qualtrics from actively managed, double-opt-in survey research panels. Self-identified Catholics were sampled randomly from these panels. Quotas and weighting for generation and ethnicity are used to ensure representativeness of the sample to the adult Catholic population relative to the most recent estimates in the General Social Survey (GSS). Because the survey did not use probability-based sampling, a traditional margin of error cannot be calculated. When opt-in panels are used, a credibility interval is used. For this survey, this is 3.5 percentage points. The United States Conference of Catholic Bishops announced their position on COVID-19 vaccination in "Moral Considerations Regarding the New COVID-19 Vaccines" in December 2020. This statement coincided with similar direction from the Congregation for the Doctrine of the Faith at the Vatican and preceded availability to the Johnson & Johnson vaccine in the US. Both statements measured the morality of vaccination with a product that was developed or tested using cell lines that were the result of abortion. The USCCB provided the following direction: In view of the gravity of the current pandemic and the lack of availability of alternative vaccines, the reasons to accept the new COVID-19 vaccines from Pfizer and Moderna are sufficiently serious to justify their use, despite their remote connection to morally compromised cell lines. In addition, receiving the COVID-19 vaccine ought to be understood as an act of charity toward the other members of our community. In this way, being vaccinated safely against COVID-19 should be considered [End Page 285] an act of love of our neighbor and part of our moral responsibility for the common good.1 At the time of the survey, 75% of US adult Catholics responding to the survey said they either plan to or have already received a COVID-19 vaccine. Among those most likely to have vaccinated or those planning to are older Catholics (96% of Pre-Vatican II Generation Catholics born before 1943 and 87% of Vatican II Generation Catholics born between 1943 to 1960). Similarly, female Catholics (81%) and those with a four-year college degree (81%) were also among the most likely to vaccinate. At the other end of the spectrum, the least likely to vaccinate were Millennials (60%, those born 1982 or later), those with less than a high school degree (60%), those residing in the western United States (70%), and men (70%). Seventeen percent say that their personal stance on abortion impacted whether they would choose to get the COVID-19 vaccine. Sixty-eight percent of those who say their stance on abortion impacted their choice have vaccinated or intend to. By comparison, 76% of those who were not affected by their stance on abortion have vaccinated or intend to. Catholics who support abortion and embryonic stem cell research are more likely than those who do not to have been vaccinated or plan on getting vaccinated. Eighty-two percent who support abortion are vaccinated or intend to be and 79% who support embryonic stem cell research are vaccinated or intend to be. Seventy-two percent who oppose abortion are vaccinated or intend to be and the same share who oppose embryonic stem cell research are vaccinated or intend to be. Twenty-three percent of adult Catholics say that statements from US bishops regarding the morality of the COVID-19 vaccines influenced whether they would or will get the COVID-19 vaccine. Seventy-seven percent of those who say these statements influenced them have vaccinated or intend to. By comparison, 74% of those who were not influenced by these statements have vaccinated or intend to. This shows that nearly a quarter of Catholics are aware of what bishops are saying regarding the vaccine. This awareness increases the more frequently Catholics attend Mass. Thirty-two percent of weekly attenders say they were influenced...
