The most common type of flexible spending account, the medical expense FSA (also medical FSA or health FSA), is similar to a health savings account (HSA) or a health reimbursement account (HRA).
While some are still in the clinical trial stage, the following vaccines are currently available: Pediarix is a combination vaccine that combines the immunizations for Diphtheria, Tetanus and acellular Pertussis (DTaP), Hepatitis B and inactivated Polio (IPV), which used to require three separate shots. Pediarix is given to children as a three dose series at 2, 4, and 6 months. So instead of 9 shots for the series to get protection against Diptheria, Tetanus, Pertussis (Whooping Cough), Hepatitis B and Polio, you can now get the same protection for your kids in just 3 shots.
Twinrix is a vaccine that provides active immunity against both the hepatitis A and hepatitis B viruses. It is given in a series of 3 injections on the same schedule as the hepatitis B vaccine: an initial dose followed by doses at 1 month and 6 months.It can also be given in 4 doses, with the initial dose followed by doses at 7 days, 21 to 30 days, and 12 months.ow Well It Works. In clinical trials, 1 month after the last dose, 100% of people were immune to hepatitis A, while 99.7% were immune to hepatitis B. But in practice, immunity may not approach these levels. Hepatitis B vaccine usually does not provide immunity for more than 95% to 97% of people.
