The members of the television crew most likely had antibodies against the influenza virus as they have probably contracted it in the UK before. Moreover, they may have received flu jabs, which strengthened their immune system against the influenza virus. In addition to this, British individuals most likely have a stronger immune system then Indian tribe members as there are a lot of medicinal drugs in the UK. Indian tribe members had probably never come into contact with the influenza virus and so had no antibodies. Therefore, when they were infected, their body had little protection against it, causing some to die and leaving others seriously ill.
