Canadian Vaccine Panel: Give the seasonal flu shot at the same time as H1N1

Laidback Al · Nov 2, 2009

Here at allnurses.com there has been some spirited discussion about whether or not seasonal influenza vaccination makes one more susceptible to novel H1N1 infection based on an unpublished Canadian study. In fact, health official in various Canadian provinces recommended skipping the seasonal vaccination and only getting the H1N1 vaccination based on the unpublished study. See this thread: https://allnurses.com/pandemic-flu-forum/higher-h1n1-flu-434777.html

Today, the National Advisory Committee on Immunization, a panel of Canadian vaccine experts, reversed that decision and recommended vaccinations of both the seasonal strains and the H1N1 strain.

It is unnecessary to delay giving seasonal flu shots this year because of concerns they might raise the risk of catching swine flu, and provinces and territories should offer the shots as soon as possible, a new recommendation from a panel of Canadian vaccine experts said Sunday.
The National Advisory Committee on Immunization did not criticize the decision by most provinces and territories to put off delivering seasonal shots until the new year - a move based at least in part on unpublished Canadian studies that show a possible link. . . . The move by most provinces and territories to delay seasonal vaccine programs this year was based on a series of as-yet unpublished Canadian studies which found people who had received a flu shot last fall were between 1.5 and two times more likely to catch H1N1 this spring.
The link, if real, was to mild disease. There was no suggestion the people who had had seasonal flu shots were more likely to end up in hospital with or dying from H1N1 infection.

And

But the committee, known as NACI, suggests even if the finding is real the risk of not vaccinating against seasonal flu is greater than the one identified by the studies.
And it is urging provinces and territories to move ahead with seasonal flu shots as soon as is feasible - even giving a thumbs up to the notion of delivering both at the same time, if that can still be arranged.
