I would suggest that its not necessarily an antivax site as suggested and it does cite sources within the body if was read  Nonetheless it raises interesting points such as efficacy being related to age and to a particular strainand does present the other side of the argument  With respect to purported antivax statements on websites this is against the standard of practice in most Canadian provinces and the CCO has fined members up to K for those shenanigans  Nonetheless we should not pick one example and make attributions for I can go to MD websites and show them endorsing questionable methods such as homeopathy  We need to be careful with giving fringe POVs too much weight here which seems to be an increasing concern
