The vaccination requirements are set by USCIS based on guidance from the Center for Disease Control (CDC), not Dr. Wingo.  All required vaccines must be as up to date as possible, including a Covid-19 vaccine approved by the World Health Organization (WHO), unless you have a well-documented reason you cannot take the vaccine signed by your physician.  Dr. Wingo is NOT able to help you get out of this requirement.
