“ Vaccines save lives. It is as simple as that. And they do so most effectively when a community achieves what is known as ‘herd immunity’: when roughly 80% of a population is vaccinated against a disease and is therefore immune to it, even the remaining 20% are protected against it because they are less likely to come into contact with an infected individual. This puts a huge responsibility on those of us who take seriously our obligations to ourselves, our families and our communities, to ensure that we are in the 80%.
