  • for maximum protection from paralytic polio, three inoculations, the second given not less than two weeks after the first

  • A minority of parents believe that the most life-saving medical advance in history does

  • more harm than good.

  • This group has undermined progress against disease in Europe and the U.S., and health

  • officials worry about further setbacks, considering who has endorsed the discredited link between

  • vaccines and autism.

  • Two years, two years old.

  • a child, a beautiful child went to have the vaccine and came back and a week later got

  • very very sick and now is autistic.

  • Here's the situation

  • The vaccine backlash took off in 1998 when the medical journal the Lancet published what

  • turned out to be a fraudulent study linking the measles, mumps, and rubella vaccine to

  • autism.

  • The journal retracted the study in 2010, and UK authorities stripped its author, Andrew

  • Wakefield, of his medical license.

  • Preventable diseases are on the rise again in the U.S. and Europe.

  • The U.S. was measles-free in 2000.

  • The number of cases spiked to 667 in 2014 though.

  • It's worse in Europe, where there were 4,000 measles cases in 2016.

  • Whooping cough has remained at elevated levels in both places since 2012, when it killed

  • 20 people in the U.S. and 10 in the U.K.

  • The choice not to vaccinate doesn't just affect individual children.

  • Since unvaccinated kids often live in geographic clusters, groups can lose herd immunity.

  • That's when a community that is so protected against a particular pathogen that the pathogen

  • itself dies out in that area.

  • If communities lose herd immunity, those who can't be vaccinated either for medical reasons

  • or because they are too young become susceptible to infection.

  • So do those who are immunized, because no vaccine is 100% effective.

  • Now here's the argument

  • In the U.S., states set vaccine requirements for school attendance.

  • Many states offer exemptions for parents who cite religious or personal beliefs that their

  • children should not be vaccinated.

  • Some public health specialists support eliminating these waivers, and in some cases courts have

  • agreed.

  • In striking down a religious exemption, Mississippi's Supreme Court cited anoverriding and compelling

  • public interestin keeping children healthy.

  • Others worry that making vaccinations more compulsory for school attendance would just

  • harden the opposition.
