For a trip to Costa Rica, the recommended vaccines include Hepatitis A and B, as well as rabies if you are going on excursions and at risk of bites, and COVID among others. It is also advisable to ensure your basic vaccination schedule is up to date. Malaria prevention may be recommended depending on the regions you will be visiting. It is best to make an appointment with your pharmacist to check if they offer vaccination services and have the necessary vaccines in stock. Additionally, you should inquire about whether the regions you plan to visit require malaria prophylaxis.
