Various different types of immunizations/vaccines are available in the world at this point in time. Each of these immunizations are widely advertised, and supported by various groups making them seem as though they are the most important. Everyone has their own opinion on vaccines, and the best piece of advice we can give is to do your research before committing to any vaccine or immunization. Dr. McCall believes immunizations are most necessary when traveling somewhere new out of the country, that will expose your body to diseases it hasn’t been exposed too yet. Dr. McCall also recommends that if you are getting multiple immunizations it is necessary to get them spread out over time. The best immunizations are those without aluminum and mercury. It is best to research and find a specific doctor who removes aluminum and mercury from their vaccines.
