How many doses of Pfizer is required?

[devusr 41]

My wife got the 1st and 2nd dose of the Pfizer vaccine but she did not get any booster. Is the booster absolutely required? Is there any documentation stating that the booster is required?

Required for what?

It seem only the first 2 are required for travel and for the I-693 medical. No booster required. (At least that's what they told me when I traveled to Brazil recently and they stamped and signed my wife's I-693 with only the first two doses)

Sorry, this is for the CR1 medical exam.

If the applicant has not received any of the listed vaccinations and the vaccinations are age appropriate and medically appropriate, the applicant has a Class A condition and is inadmissible. Generally, all age appropriate vaccine rows of the vaccination assessment must have at least one entry before the assessment can be considered to have been properly completed. However, the COVID-19 vaccination (required as of October 1, 2021) differs in that the applicant must complete the entire vaccine series (one or two doses depending on formulation).^[4]

 

So 2 doses are enough
