https://www.vetnurse.co.uk/f/clinical-discussions/21980/nobivac-l4 Has anyone moved from L2 to L4? MSD is claiming that more dogs (50%) have tested seropositive for serovars Copenhageni and Bratislava, than Ictero and Canicola (which make up L2) (34%). n = 953 tested positive altogether I don&#39;t know how commonen-USTelligent Community 10https://www.vetnurse.co.uk/thread/144099?ContentTypeID=1Mon, 08 Jul 2013 09:11:29 GMT1a0763ec-3885-442c-853e-6cef656dfec5:8a04036a-9d65-4e6d-9b4e-ce4566183604Mark Hedberg<p>The reason for this is that from the point of view of the 2 new serovars, it&#39;s a first vaccination. So they need that booster the very first time, after which it&#39;s annual boosters as normal.&nbsp;</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/144082?ContentTypeID=1Sun, 07 Jul 2013 15:17:45 GMT1a0763ec-3885-442c-853e-6cef656dfec5:ff123b5e-2129-4e5c-ba47-a06a127b29edNicola Smith<p>We have talked about it but from our understanding adult dogs cant just have a single booster including the new lepto they would have to have 2 injections for the new type to actually work and not sure how workable that would be - especially as it is twice the cost of the lepto 2. Think it could cause a lot of issues with people swopping vets as not everywhere will have it - try explaining that to clients!! We will be staying as we are for now.</p> <p>&nbsp;</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/143867?ContentTypeID=1Sun, 30 Jun 2013 10:49:06 GMT1a0763ec-3885-442c-853e-6cef656dfec5:1331ef0f-8b7f-4dfd-936f-64697cd6d7aaRachel Jayne<p>We are moving soon, vets wanna read up on all the bumph Will let you know..</p><div style="clear:both;"></div>
