With 100% immunization, and 100% efficacy of the vaccines, one out of seven deaths among young children could be prevented, mostly in developing countries, making this an important global health issue. [3] Four diseases were responsible for 98% of vaccine-preventable deaths: measles, Haemophilus influenzae serotype b, pertussis, and neonatal ...
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.
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).

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.
As of Sunday, at least 16,183 people had filed complaints with the Centers for Disease Control and Prevention that they'd developed tinnitus, or ringing in their ears, after receiving a Covid vaccine.
Assuming a vaccine is 100% effective, then the equation used for calculating the herd immunity threshold can be used for calculating the vaccination level needed to eliminate a disease, written as V c. [2] Vaccines are usually imperfect however, so the effectiveness, E, of a vaccine must be accounted for:
