While a slight majority (51%) of American likely voters say they will take the COVID-19 vaccine when available, 36% say no, leaving 14% unsure. In other words, exactly half of the population are unwilling and hesitant about getting the COVID-19 vaccine.

When asked about reasons for not getting the vaccine, the most common answer (59%) is "afraid of vaccine side effects."

A follow-up question asked respondents how safe they believe the COVID-19 vaccine would be when made available. While a slight majority (51%) believe it will be safe, 29% report unsafe, and 21% are not sure — keeping consistent with the divide over the question of taking the COVID-19 vaccine.

The most common answer among the nearly 3 in 10 Americans who believe the vaccine will be unsafe, cite "rushed/needs more testing" as a concern.
