Measles exposure warning issued for four New York counties

A traveler from Europe may have exposed people to measles in Chemung, Genesee, Livingston and Niagara counties, the New York state Department of Health warned Saturday. The traveler, who has a confirmed case of measles, visited multiple sites in upstate New York on April 30, and May 1-2. Anyone who visited the following locations on these dates and times could have been exposed:

  • Old Country Buffet, 821 Country Route 64, Elmira, between 1 and 4 p.m. April 30.
  • Ontario Travel Plaza on the New York state Thruway in Le Roy, between 4 and 6:30 p.m. April 30.
  • Sheraton Niagara Falls, 300 3rd Street, Niagara Falls, from 5:30 p.m. April 30 to 9:30 a.m. on May 2.
  • Niagara Falls Urgent Care, 3117 Military Road. Suite 2, Niagara Falls, between 3 and 6 p.m. May 1.
  • Exit 5 on Interstate 390 in Dansville, from 9:30 a.m. to noon May 2.

The times reflect the period that the infected person was in these areas and a two-hour period after the individual left the area. The virus remains alive in the air and on surfaces for up to two hours.

takyon: Measles outbreaks have been reported in Okinawa, Pennsylvania, and Missouri recently.

    Your explanation does not work because the Indian study measured immunity after *two* vaccinations. It is plausible that the first vaccination may have been neutralized by maternal antibodies, but the second one should have had the full effect. Look also at the result of the third dose: immunity was spread to 70%, up from 20%. The increase of 50 points appears to indicate initial vaccine effectiveness of over 50%, with immunity waning over time. This hypothesis would explain why in the US two full doses are sufficient to maintain 97% effectiveness at the time of testing (I was unable to find the numbers on the age at which the testing was done, if any test was done at all). Then, over, say, 5-10 years, immunity wanes and tends to disappear completely. So I still say that it would be best to assume that recurrent vaccination may be required.

    It is plausible that the first vaccination may have been neutralized by maternal antibodies, but the second one should have had the full effect.

    I think the first one given in the presence of maternal antibodies is supposed to still induce an "innate immunity" T-cell response which later "interferes" with the B-cell (antibody) response to the vaccine. I can't find a mention of it at the moment though...

    And sure, there is waning anyway (see other discussion in this thread about that) but that seems much quicker than usually reported.
