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.
In all clinical trials, the typical process starts with a screening period. The screening period starts with the signing of the informed consent. During the screening period, inclusion/exclusion criteria for the study participation will be checked / tested. Subjects who meet all inclusion criteria and do not meet any exclusion criterion will be eligible to be randomized (in randomized trial) or to be dosed (in non-randomized trial).
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. These studies also may show which medical approaches work best for certain illnesses or groups of people.Clinical trials produce the best data available for health care decisionmaking.n later phases of clinical trials, researchers learn more about the new approach's risks and benefits. A clinical trial may find that a new strategy, treatment, or device. 1  improves patient outcomes; 2  offers no benefit; or. 3  causes unexpected harm.
