If you received Pfizer's coronavirus vaccine, you'll likely need a third dose within a year. 

Pfizer's CEO said people are likely to need a booster dose of the vaccine six to 12 months after their first round. 

From there, it will be an annual re-vaccination. 

Officials are still testing the timing of follow-up vaccine doses. 

Right now, data show the Pfizer vaccine is effective against a worrying variant of coronavirus first seen in South Africa.
