There may have also been unknown vaccine and supply shortages and it is possible that parents may have been uncomfortable with their child receiving multiple vaccinations on the same day, among many other potential reasons [ 16, 17].
On the other hand, with multiple vaccinations, such as the case with Hannah, there is also a risk of overtaxing the immune system, and likewise triggering regression into autism.
Two immunization protocols were followed: the immune response protocol, in which the mice received multiple vaccinations prior tumor challenge, and the therapeutic immunization protocol, in which the mice were challenged with C3 tumor cells before administration of the vaccines.
Details of model development, parameter calibration, stability analysis, and numerical simulations of multiple vaccinations are described in the following sections.
Impulsive stabilization using the Lyapunov method will be considered in the future to provide conditions on parameters such that the high-tumor equilibrium may be stabilized using impulsive control through manipulation of strength and frequency of the multiple vaccinations.
A review of eight studies found that multiple vaccinations had no effect on the incidence of the disease.
However these changes in multiple vaccinations have little impact on the magnitude of the clonal CD8 + T cell immune response and therefore have very little impact on reducing tumor growth.
Most schools had more than one class of girls in grade 6, so multiple vaccinations sessions were run on the day of vaccination.
In case of the need for multiple vaccinations against brucellosis and other diseases, injection of 19-BA vaccine should occur one month after or prior to administration of other vaccines.
Finally, we used the calibrated model to explore the impact of multiple vaccinations on tumor growth to improve anti-tumor immunity, a scenario that is difficult to test experimentally using pre-clinical mouse models but could be potentially used in the clinic to treat patients.
