What shots do I need to take if I am traveling to Costa Rica for 4
days? I will specifically be in Playa Ocotal in the Guanacaste
Province in the northern pacific coast of Costa Rica. Thank you.

Hi andyssi:

There are no shots *required* to travel to Costa Rica:

Quote: "Q. Are immunizations required?
From a general health standpoint, Costa Rica is one of the safest
destinations in the developing world. This is largely due to high
health standards in our country. Thus, there are no required
immunizations when traveling to Costa Rica...However, it is always
wise to keep up your basic shots such as tetanus and diphtheria. Risk
of contracting malaria is minimal, but for itineraries that include
the Caribbean lowlands, travelers might wish to take the extra
precaution of prophylactic medicine such as chloroquinine.
Decisions about immunizations and anti-malarial medications should be
made on a personal basis after consultation with your personal
physician."

While no shot are required, the following site gives a very good
breakdown of immunizations *recommended* for travel to Costa Rica:
