Purpose of review This review summarizes herd immunity, focusing on conceptual developments with application to vaccination programs. Recent findings The conventional idea of herd immunity is based on the relationship between the transmission dynamics of infectious agents and population immunity. However, there have been some recent conceptual developments in vaccine ‘herd immunity’ or ‘herd protection’ that address the complexities of imperfect immunity, heterogeneous populations, nonrandom… 

Vaccination exemptions: implications of decline in vaccination rates.

The implementation and widespread use of vaccines has resulted in a dramatic decline in morbidity and mortality due to preventable diseases, particularly among those for whom vaccination has been routinely recommended for use in children before 1990.

The Role of Herd Immunity in Control of Contagious Diseases

The concepts regarding herd immunity; the diseases which can be accounted with it; its link with vaccination strategies and part of the disease eradication are tried to enlighten.

Dissecting the indirect effects caused by vaccines into the basic elements

The necessary conditions for achieving optimal herd protection, including high quality vaccine-induced immunity, substantial effect on the force of infection, and appropriate vaccine coverage and distribution are discussed, as well as the conditions under which age shifts are likely to occur.

The best understanding of herd immunity therefore comes primarily from previous epidemics, and a greater proportion of immune individuals among health care workers can help prevent spread of infectious agent to nursing home patients, which is why influenza vaccination is required for staff at some hospitals.

Analysis of Herd Immunity Using Vaccination and Recovery Data Sets

The Covid-19 pandemic that created a situation of public health emergency worldwide called for an urgent requirement of vaccine to prevent further spread of the disease. Successful vaccines started

Pneumococcal Vaccination Strategies. An Update and Perspective.

Continued efforts are needed to address the vaccine efficacy in the waning immunity of the ever-aging population, the implementation of vaccines using two different vaccines under very specific schedules and their real world clinical and cost effectiveness, and the development of next generation pneumococcal vaccines.

Prospective Promising Signs of Herd Immunity in COVID-19 Transmission Suppression Via Vaccination

This review is intended to make the perception herd immunity needs to play in COVID-19 transmission concealment inferable from its circumspect viability for the destruction of numerous maladies and give the premise to vaccines and their applications serving as a proviso for immune individuals that will prompt a huge decrease in disease event and spread.

Vi conjugate vaccine was conjugated to rEPA, a recombinant exoprotein A from Pseudomonas aeruginosa, which showed higher and longer lasting anti-Vi IgG in adults and children than Vi alone in high endemic areas and showed no interference with the routine vaccines.



Vaccine herd effect

The herd effect has had a major impact in the eradication of smallpox, has reduced transmission of pertussis, and protects against influenza and pneumococcal disease.

Meningococcal vaccines and herd immunity: lessons learned from serogroup C conjugate vaccination programs

The magnitude of the herd effects following MCC vaccination was largely unanticipated, and has important consequences for the design and evaluation of new meningococcal vaccines.

Herd immunity: recent uses in vaccine assessment

Human communities defend themselves against specific infectious agents in a way that extends beyond the simple sum of the immune status of its individuals. By analogy with individual immunity to

Estimation of measles vaccine efficacy and critical vaccination coverage in a highly vaccinated population

Analysis of a large outbreak in a German public school to show how estimates of key epidemiological parameters such as the basic reproduction number (R0), vaccine efficacy (VES) and critical vaccination coverage (pc) can be obtained from partially observed outbreaks in highly vaccinated populations.

Acellular Pertussis Vaccine Safety and Efficacy in Children, Adolescents and Adults

DTaP vaccination appears to establish herd immunity after sufficient uptake within communities and countries, and the economic impact of pertussis and transmission from adults to vulnerable infants provides a cost-benefit justification for widespread use of DTaP vaccines in all age groups with routine boosting every 10 years.

Updated Postlicensure Surveillance of the Meningococcal C Conjugate Vaccine in England and Wales: Effectiveness, Validation of Serological Correlates of Protection, and Modeling Predictions of the Duration of Herd Immunity

Modeling suggested that protection against carriage persists for at least 3 years and predicted the stabilization of serogroup C disease at low levels (fewer than 50 cases per year) up to 2015-2016.

Direct and indirect effectiveness of influenza vaccination delivered to children at school preceding an epidemic caused by 3 new influenza virus variants.

LAIV delivered to elementary-school children before an epidemic caused by 3 new variant influenza viruses generated significant cross-protection for the recipients and indirect (herd) protection for the community.
