Varicella (chicken-pox) vaccination is now included in the childhood vaccination schedule and we find folk are keen to have this vaccine. Folk are aware that chicken pox can be miserable illness and necessitates absence from school.
With vaccination measles, mumps and rubella are much less commonly seen and there is less awareness of how serious these can be and how effective the vaccine is at preventing these infections.
Herd immunity refers to when immunity in a population is high because of vaccination (or past infection) and infection is unlikely to spread rapidly. Unfortunately we need a vaccination rate of 95% or higher with two doses of the MMR (measles, mumps, and rubella) vaccine to prevent outbreaks and ensure herd immunity against measles. Because measles is extremely contagious, this high threshold is necessary to prevent the virus from spreading, as even small gaps in vaccination coverage can lead to outbreaks.
With a decreased awareness of what particularly measles looks like we have noticed that vaccination uptake has reduced and this means that unvaccinated children are no longer protected by herd immunity in our local population and an outbreak is possible. For more information have a listen to this podcast and any of our doctors or practice nurses will be happy to chat with you if you have any queries.
Measles, mumps and rubella are all serious illnesses. They are also all preventable. Vaccination is safe and effective. But take up of the vaccine is not what it should be.
