Knowing how much we travel internationally, a friend told us we might want to consider getting a polio booster! I said we both have all of our shots but she told me the CDC is encouraging fully vaccinated people to get a booster for international travelers! I spoke with my doctor and she agreed. Even if your destination is not on the list of countries, you could come into contact with someone who has this highly contagious disease just connecting through Heathrow on the trams and shuttles. Also, Medicare completely covered the cost! https://www.vaccineadvisor.com/news/going-abroad-cdc-warns-travelers-about-polio-risk-in-several-countries/
