Sample Size calculation for a survey

I want to calculate the sample size for a survey to evaluate maternal risk perception of disease and its association with vaccination status. So the outcome has two levels Fully vaccinated and partially vaccinated. The exposure variable is risk perception (high risk and low risk). I want the alpha level to be 0.05 and CI 95% with power 80%

One previous study found that among the high risk group the proportion of fully vaccinated was 62% and among the low risk group perception, the proportion of fully vaccinated children was 35% . The same study reports that the odds of being fully vaccinated in high risk grp is 1.81 compared to low risk.

I will greatly appreciate any help I can get on this.
