Je vous remercie beaucoup pour vos réponses, ça m'aide!Â
C'est super sympa! 
Une question persiste! A propos du vaccin "Gardasil". Si je veux devenir "permanent resident" un jour. J'ai trouvé ceci sur le site "Center for Disease Control and Prevention:
"Is the human papillomavirus vaccine (HPV) still required under the new vaccination criteria?
No. HPV does not meet the new vaccination criteria set by CDC and is not required for the immigrant medical exam.
HPV is not known to cause outbreaks. Also HPV is the most common sexually transmitted infection (STI) in the United States and is not close to being eliminated at this time.
CDC will use the new vaccination criteria for vaccines recommended by the Advisory Committee on Immunization Practices (ACIP) to decide which vaccines will be required for U.S. immigration. The criteria will be used at regular periods, as needed.
The criteria are:
  The vaccine must be age-appropriate* for the immigrant applicant
  The vaccine must protect against a disease that has the potential to cause an outbreak.
  The vaccine must protect against a disease that has been eliminated or is in the process of being eliminated in the United States.
*ACIP recommends vaccines for a certain age range in the general U.S. public. These ACIP recommendations will be used to decide which vaccines are age-appropriate for the general immigrant population.
Ici, je pense comprendre que le vaccin serait recommandé pour une certaine tranche d'âge. Est-ce correcte?
Sur un autre site "US Citizenship and Immigration Services" j'ai trouvé cela:
. I heard that the vaccine against herpes zoster (zoster) and the Human Papillomavirus (HPV) are required vaccines. Is this true?
A. From Aug. 1, 2008, until Dec. 13, 2009, the zoster and the HPV were required vaccines for immigration purposes. However, the zoster vaccine was not available from Aug. 1, 2008, through Dec. 13, 2009, and USCIS posted a message on the Web to inform civil surgeons they could annotate the vaccination record with "not available" if they were not able to obtain the vaccine. In 2009, CDC changed the vaccination requirements based on ACIP's recommendations. As of Dec. 14, 2009, the zoster and the HPV vaccine were no longer required.
Est-ce que quelqu'un pourrait me dire ce qu'il comprend avec ces articles, s'il-vous-plait?
