Do you still remember when you were vaccinated[進(jìn)行預(yù)防接種] when you were a baby？ Chances are you have no clue about it， except that you may have bawled[大叫] during inoculation[接種]. Then one day， when youre old enough and you check your birth certificate， you learn back then you had received a range of shots to prevent tetanus[破傷風(fēng)]， polio[小兒麻痹癥]， meningitis[腦膜炎] and measles[麻疹]. Arent you thankful that youve lived in a good health？ I certainly am.

In China， together with several other immunization shots， measles vaccination is mandatory[強(qiáng)制的]. As it is in the United States. However， American parents seem to be more doubtful about the effects of vaccination than the Chinese. The recent Disneyland measles outbreak speaks for itself. A report found that most of the victims who had become infected measles were in fact unvaccinated.

I was shocked to learn that some American parents chose to forgo[放棄] vaccination given to their underage children based on their religious and unscientific concerns. Some of them fear immunization will be detrimental to their infantsfledgling immune system. And some others， like the religious Amish people， view immunization as putting faith in man over their god.

The opposition， however， blames the anti-vaccination parents for creating a public health risk. After all， the virus can live on a surface or hang in the air for as long as two hours after an infected person has coughed or sneezed. Even though the U.S. health authorities require infants at 12 months old to receive their first dose of the measles vaccine， there are still many who disobey across the country.

After the measles outbreak， amid heated debate， law makers finally started to make changes about vaccination. For example， in California where the outbreak started， new legislation is proposed to outlaw waivers[自動(dòng)放棄] that allow parents to exempt[免除] their children from receiving basic vaccinations for religious or personal reasons. In some states， kindergartens and lower-grade schools even ban kids who have not received a measles vaccination from classes.

Dont these measures come too late？ The Disneyland outbreak has already spread beyond the theme parks from the onset of 59 confirmed cases to over 100 cases around the country. But as the saying goes， its better late than never. American parents should really think twice when doing about vaccination for their kids. After all， it concerns more than the health of an individual but of the public.
