< BACK NEXT > 5 of 8 - Herd immunity breakdown by freeloaders
As we saw in the previous scenario, a small number of freeloaders are also protected by herd immunity.

As the number of freeloaders increases however, a critical point is reached where by herd immunity breaks down completely.

Both freeloaders and those that cannot be vaccinated for health or age reasons are no longer indirectly protected by herd immunity.

In this scenario that point has been reached.

The result is that very often all susceptibles are infected.

As this is a longer infection scenario, it's displayed at a faster rate.
