The resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease, especially through vaccination.‘the level of vaccination needed to achieve herd immunity varies by disease’
- ‘The goal of measles control is to raise population immunity above herd immunity threshold and eventually to interrupt indigenous virus transmission.’
- ‘Of course, the issue of herd immunity is further complicated by the amount of cross protection afforded by commercial vaccines, as no vaccine will contain every strain or every possible antigen.’
- ‘Because of the herd immunity that exists because of mass vaccination, the unvaccinated are also protected.’
- ‘The vaccination is seen as a way to achieve herd immunity as it stops the spread of the illness from children to others that are vulnerable to flu.’
- ‘They found no evidence that vaccination prevents viral transmission, putting the whole herd immunity myth once again into question.’
- ‘As adolescents are the only group in which carriage rates have been studied, these data provide more robust evidence of herd immunity across the whole population.’
- ‘Uncertainty about the level of herd immunity generated by vaccination programmes limits modelling of the potential benefits of booster vaccination.’
- ‘The goal is herd immunity, where the proportion of people susceptible to infection in a physically interacting population is so low that transmission of infection is unlikely.’
- ‘A good herd immunity effect dramatically controlled the disease initially.’
- ‘Neither one really addressed the question of mandatory vaccination and its effect on mortality and herd immunity.’
- ‘Children whose parents opt not to vaccinate decrease herd immunity, which protects populations from communicable diseases.’
- ‘High immunisation rates may result in herd immunity, which increases protection for all residents, including the weakest patients.’
- ‘One correctly pointed out that if universal smallpox vaccination were offered, those who couldn't be immunized would be protected by herd immunity.’
- ‘There, public health officials have now documented mass HPV vaccination and the first glimmers of herd immunity.’
- ‘Thus herd effect is a reflection of both herd immunity and the inhibitory effect of vaccine-induced immunity on the shedding of the pathogen necessary for new infections to occur.’
- ‘The level of vaccination needed to achieve herd immunity varies by disease but ranges from 83 to 94%.’
- ‘The result has been outbreaks of measles - children have received ineffective injections leading to a breakdown in herd immunity.’
- ‘This group may also have reduced herd immunity and generally produce lower quantity and quality of colostrum, resulting in greater risk of disease and potentially reduced production in their offspring.’
