§ Mr. Iain Macleod
The results of the trial of a new influenza vaccine carried out last winter have now been given preliminary study by a committee of the Medical Research Council. Over 12,000 individuals took part in the trial. Influenza was diagnosed in 3 per cent. of the group given the new vaccine and in 49 per cent. of the group given an older type of vaccine; 6,340 volunteers received the new trial vaccine of the virus A type, and 192 had influenza; 6,370 received an older type and 309 had influenza. These results are considered to be sufficiently encouraging to justify further research on the vaccine with a view to improving it.
