Vaccines ain’t perfect, but it would have been a lot worse without them

It seems to turn out that in a recent measles epidemic (by modern standards) in NYC, “patient zero” was, indeed, fully vaccinated. And some of the folk she infected were vaccinated or previously exposed as well.

So yup, vaccines aren’t perfect and neither are human antibodies. But it would have been a lot worse if more people would have been susceptible (that is, unvaccinated):
Results. The index case had two doses of measles-containing vaccine. Of 88 contacts, four secondary cases were confirmed that had either two doses of measles-containing vaccine or a past positive measles IgG antibody”

  1. Yes, this point is missed by most critics of vaccines. The critics ignore the benefits.

    Just like with summer heat and winter cold. Many more lives are saved by winter warmth than are lost by summer heat.

    Ditto practically every other cost and benefit from global warming. The only way the economists can show net economic loss from global warming is by ignoring the benefits.

    Same with vaccines and a lot of other junk science.

  2. Measles causes almost a million deaths a year in unvaccinated populations globally. Compare that to a few dozens in the U.S. who “have measles” annually.

    The funny thing is, measles is antigenically stable, so it is essentially the same measles our ancestors had a century ago, and the first ever measles vaccine still works. Controlling measles is child’s play compared to flu.
