Check Vaccine Requirements Eight Weeks Before You Go

If you plan to travel, you may need to be vaccinated against some diseases in other parts of the world. Some vaccines must be given well in advance to allow your body to develop immunity.

For some vaccines to become protective, several doses spread over several weeks or months.

According to the U.K. travel office on October 22, 2024, prospective international travelers should visit a G.P. or a private travel clinic at least 6 to 8 weeks before traveling bread in 2024.

In the U.K., the NHS routine immunization schedule lists vaccines that protect people against multiple diseases but does not cover all infectious diseases found overseas.

Furthermore, some countries require proof of vaccination (meningitis, polio, or yellow fever), which must be documented on an International Certificate of Vaccination or Prophylaxis (ICVP) before entering or leaving a country.

Even if an ICVP is not required, the U.K. recommends keeping a record of the vaccinations you have had with you, such as chikungunya, dengue, and measles.

In the United States, the CDC's travel advice website offers similar advice.
