A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. [1] [2] The safety and effectiveness of vaccines has been widely studied and verified.
However, the concept of vaccine overload is biologically implausible, as vaccinated and unvaccinated children have the same immune response to non-vaccine-related infections, and autism is not an immune-mediated disease, so claims that vaccines could cause it by overloading the immune system go against current knowledge of the pathogenesis of ...
Vaccines are a major influence in the health industry towards preventing illness, highlighting the need to communicate on why it is important to have one. A study conducted by the Strategic Advisory Group of Exerts on Immunization (SAGE) worked to see if vaccine hesitancy was determined by poor communication given to the public.

The core items are deemed to be the most cost-effective options for key health problems and are usable with little additional health care resources. [4] The complementary items either require additional infrastructure such as specially trained health care providers or diagnostic equipment or have a lower cost–benefit ratio . [ 4 ]
Development and testing of more effective vaccines is underway. [228] Two registrational trials have evaluated vaccine candidates in active immunization strategies against S. aureus infection. In a phase II trial, a bivalent vaccine of capsular proteins 5 & 8 was tested in 1804 hemodialysis patients with a primary fistula or synthetic graft ...
A COVID-19 vaccine is intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus that causes coronavirus disease 2019 . Prior to the COVID-19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing diseases like severe acute ...
