HealthDay News — Most older US adults are prepared to roll up their sleeves to get an updated COVID-19 booster shot once one becomes available, a new poll shows. The poll, conducted in late July online and by phone, included a nationally representative sample of 1024 adults over 50.

About 3 in 5 people over 50 (61%) who have gotten at least one dose of COVID-19 vaccine say they would get an updated booster that offers protection against the new variants that have emerged, the University of Michigan poll found. And even more might get the booster if their doctors specifically recommend it, the National Poll on Healthy Aging suggests.

Groups especially hard hit by COVID-19, people older than 65, Black adults over 50, people with low incomes, in particular are interested in the booster. About 68% of people in each of those groups said they are likely to get a booster.

How people felt about getting a booster depends a lot on their current vaccination status. Only 24% of people who have been vaccinated but not boosted said they are very likely to get a fall booster, compared with 56% of those who have gotten one booster and 88% of those who have had 2. The poll shows that only 19% of 50- to 64-year-olds and 44% of people over 64 have gotten the full course of vaccination with 2 booster doses. On the other hand, 17% of people over 50 have not been vaccinated at all.

A doctor’s advice also matters. About 77% of older adults say their health care provider’s recommendation about COVID-19 vaccination is very or somewhat important to their decision to get vaccinated. A doctor’s advice was most important for those over 65 (56%), Black people (79%), retirees (56%), or those with incomes under $30,000 (56%).
