DISCUSSION CHAIRMAN ZHDANOV: Thank you, Dr. Horstmann. This paper is now open for discussion. DR. GEAR: I should like to ask Dr. Horstmann if she considers that her results are a recommendation for feeding trivalent vaccine, rather than monovalent vaccine? Feeding trivalent vaccine more than once gives an opportunity for the intestinal tract to become infected with the particular type for which antibodies are not present, and 1 would be grateful to have Dr. Horstmann tell us whether she thinks that her results are in favor of feeding triple vaccines, rather than monovalent vaccine. DR. HORSTMANN: I think the results have to be interpreted in relation to the environment, the age, and immune status of those to be vaccinated. On the basis of our findings, I would not recommend trivalent vaccine if one expects to accomplish rapid immunization of a triplenegative child with one dose of vaccine. Perhaps when we know more about optimum dosage level combinations for any particular preparation a single dose of trivalent vaccine will be more effective than is currently the case. In the meantime, my feeling is that if one wishes to use the trivalent vaccine, it should be given repeatedly, and at somewhat longer intervals than we used. DR. Cox: These results confirmed what we found out about our Type 2 strain. The Type 2 strain of course has been the most modified by laboratory manipulations of any of the strains we have. Actually, our Type 3 strain is the only one of our strains that has never been adapted to a foreign host. We think this may be partially responsible for its greater ability to infect the human gut. Furthermore, this particular batch of vaccine was made up in a considerable hurry and did not contain as much virus as we had intended. Data to be presented later will show results obtained with a vaccine containing more virus, namely, 6.1 logs of virus per strain. Actually, 121 in the Florida trials, where we apparently obtained our best results, we compensated somewhat for the Type 2 deficiency by actually putting in a bit more than 6.1 logs per dose. We have found, by asking people who have worked with monovalent versus trivalent, that it is much better to feed trivalent twice, and certainly at a longer interval than one month, than to carry out monovalent feedings. We believe that there is still resistance in the gut which may interfere with feeding trivalent vaccine at a one-month interval. But when it comes to practicality and expense, it is much easier to feed trivalent twice than it is to feed the monovalents separately. We have been considerably encouraged by what we have seen with the trivalent vaccine because I think the results Dr. Horstmann obtained are probably the poorest we have seen and certainly somewhat inferior to our other data. This may be due to the quantity of virus fed, and perhaps to some other factors we do not understand as yet. To be sure, they are sufficiently encouraging so that we feel it worthwhile to go ahead and solve this problem. There is no doubt in our minds that this can be done. DR. FLIPSE: I should like to ask Dr. Horstmann if she has, and if so could make available for comparison, the conversion data at the 1:4 level. There is considerable disagreement, obviously, as to its significance, but it would make it possible for those of us who are reporting data in terms of both 1:4 and 1:16 conversions to compare her data with other data. DR. HORSTMANN: As I indicated in our study, all of the homotypic negative children who became infected and converted, with one or two possible exceptions, developed antibody titers considerably greater than 1:16. Therefore, the conversion rates at 1:4 are virtually the same as at 1:16. Furthermore, we used the CPE tube neutralization method in testing the sera. This method measures high avidity antibody and gives lower titers than the pH colorimetric test which
122 Discussion 122 Discussion~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I assume was used in Dr. Flipse's work. The results are therefore not directly comparable because of the differences in technique. Titers of 4 or 8 by the pH method (which measures low avidity antibody) are apt to be
