LETTER: Vaccinations should be required of citizens and visitors

It now appears that diseases such as measles are being imported by infection carriers from other countries that do not insist on immunization.

The only answer is to inoculate anyone entering the United States that does not have a certificate of immunization, much like what was demanded of anyone having an immunization for smallpox.

All nations were supposed to comply, and its success was proven 100 percent.

So must all nations deal with the several childhood diseases such as measles, whooping cough, mumps, scarlet fever and anything else the wisdom of doctors call proper.

Parents in the United States that refuse to inoculate their children should be charged with public endangerment and made to pay the penalty.
