Vaccines are incredibly beneficial for two reasons. The first is the obvious one; for the individual receiving them they provide near-immunity to a whole range of horrendous diseases, many of which can prove fatal or have lifelong consequences for those who become infected. The risks associated with them are so small it’s hard to even connect them with the vaccines themselves and are far more likely to simply be the background noise than anything else. Secondly, when a majority of the population is vaccinated individuals who can’t be vaccinated (such as newborns) or those idiots who simply choose not to gain the benefit of herd immunity. This prevents most diseases from spreading within a community, providing the benefits of vaccinations to those who don’t have them. However there’s a critical point where herd immunity stops working and that’s exactly what’s starting to happen in northern California.
A recent study conducted by researchers working for Kaiser Permanente analysed the vaccination records for some 154,000 individuals in the Northern California region. The records cover approximately 40% of the total insured individuals in the area so the sample size is large enough for it to be representative of the larger whole. The findings are honestly quite shocking showing that there were multiple pockets of under-immunization (children not recieving the required number of vaccinations) which were signficantly above the regional mean, on the order of 18~23% within a cluster. Worst still the rate of vaccination refusal, where people declined any vaccinations at all, was up to 13.5%. It’s a minority of people but it’s enough to completely eradicate herd immunity for several horrible diseases.
For diseases like pertussis (whooping cough) and measles the herd immunity rate may only start kicking in at the 95% vaccination rate, mostly due to how readily they can spread from person to person. That means that only 5% of the population has to forego these vaccinations before herd immunity fails, putting at risk individuals directly in harms way. Other diseases still maintain herd immunity status down to 85% vaccination rates which some of the clusters were getting dangerously close to breaking. It’s clusters like this that are behind the resurgence of diseases which were effectively eradicated decades ago, something which is doing far more harm than any vaccine ever has.
It all comes down to the misinformation spread by several notable public figures that vaccinations are somehow linked to other conditions. It’s been conclusively proven again and again that vaccines have no link to any of these conditions and the side effects from a vaccination rarely amount to more than a sore arm or a fever. It’s one thing to make a decision that only affects yourself but the choice not to vaccinate doesn’t, it puts many other individuals at risk, most of whom cannot do anything to change their situation. You can however and the choice not to is so incredibly selfish I can’t begin to explain my frustration with it.
Hopefully one day reason will prevail over popularity when it comes to things like this. It’s infuriating to think that people are putting both themselves and others at risk just because some celebrity told them that vaccines were doing them more harm than good when the reality is nothing like that. I know I’ve beaten this horse several times since it died but it seems the bounds of human stupidity is indeed limitless and if I can make even just a small difference in those figures than I feel compelled to do so. You should to as the anti-vaxxers need a good and thorough flogging with the facts, one that shouldn’t stop until they realise the error of their ways.
