The Immunization Surveillance, Assessment and Monitoring program of the WHO monitors and assesses the safety and effectiveness of programs and vaccines at reducing illness and deaths from diseases that could be prevented by vaccines. [5] Vaccine-preventable deaths are usually caused by a failure to obtain the vaccine in a timely manner.
The Centers for Disease Control and Prevention support initiatives such as Health in All Policies and HI-5 (Health Impact in 5 Years), and collaborative efforts that aim to consider prevention across sectors [149] and address social determinants of health as a method of primary prevention for chronic disease.
The purpose is to reduce the risk of death and suffering, [1] that is, the disease burden, even when eradication of the disease is not possible. Vaccination is the chief type of such immunization, greatly reducing the burden of vaccine-preventable diseases. Immunity against infections that can cause serious illness is beneficial.
No, the flu shot can’t cause the flu. The flu shot contains either an inactivated virus (which means it’s no longer infectious) or a particle that’s designed to look like a flu virus to your ...
Numerous observational studies and randomised trials (RCTs) have found that the impact on mortality of live and inactivated vaccines differ markedly. All live vaccines studied so far (BCG, measles vaccine, oral polio vaccine (OPV) and smallpox vaccine) have been shown to reduce mortality more than can be explained by prevention of the targeted infection(s).

Symptoms typically appear 1–3 days after infection and include fever, lethargy, anorexia, weight loss, labored breathing, coughing, sneezing, and nasal discharge. In sows, pregnancy may be aborted.
