In the latest Economist/YouGov poll, nearly half of vaccinated respondents (49%) say they have been injected with the Pfizer vaccine, and 40% have received the Moderna vaccine. Just one in 11 (9%) have gotten the Johnson & Johnson vaccine.
Three-quarters of vaccinated Americans experienced no side effects (75%). Some did, however, and more people who received the two-dose Moderna vaccine report side effects (28%) than those who have been injected with either the two-dose Pfizer-BioNTech (19%) or the single-dose Johnson & Johnson vaccines (16%).
Vaccinated adults over 65 (17%) are less likely than 30-to 44-year-olds (31%) and those under 30 (27%) to report experiencing side effects to the shot.
