Pretzel Aye, and
that’s (part of) the rub.
The video touches on the concept of “herd immunity” without delving into it. Let’s use COVID as an example. For COVID prevention by herd immunity (which is really just breaking the chain of transmission by having enough of the population immune either by prior infection of the virus or immunization) you need 90-95% of the population immune. This just decreases the risk of encountering someone who is shedding the virus and is therefore a source of infection.
Lack of herd immunity increases the vulnerability of high risk patients like the elderly, those with co-existing risk factors, young children, etc.
However, for COVID, the vaccines do not completely eliminate the chance of being infected in all patients. But they are very effective in reducing the severity of the disease, decreasing hospital admissions, and lessen the likelihood that those breakthrough cases infect others.
This varies from viral strain to viral strain.
Places like
classrooms are like a buffet of susceptible people to viruses. The vaccine deniers are just setting their children up for multiple vaccine preventable diseases such as measles.
At this moment, the two most concerning are the measles and whooping cough viruses and we are seeing outbreaks in multiple states.
