in the u. s. the centers for disease control has a "catch-up" vaccination schedule (<link> but i am not sure if canada has a similar resource. i am a huge supporter of vaccines but realistically being vaccinated may not be protective against bronchitis (which is usually viral). influenza and pneumonia vaccines may help him however.
my 12 yr old brother has not had any vaccinations. how would he go about being immunized now? the immunization schedule. here in alberta begins at 2 months. for whatever reason my parents did not immunize my brother. he frequently gets acute bronchitis (for about a week) and always gets bronchitis when he gets sick. the last time i had taken him in for antibiotics the doctor asked if he had all his vaccinations. i told him that i thought he was up to date with his immunization schedule but later found out he had never been immunized. how would being vaccinated affect my brother frequently having bronchitis?
