Do kills by healed / boosted teammates count as assists for the Field Medic?

This mechanic is something from games like Team Fortress 2.

As far as I know, medic healing has no effect on kills/assists. The skills

  • Adrenaline shot
  • Focus injection
  • Coagulant booster

are merely buffs, and unlike TF2 (etc), do not make assists etc count. Damaging Zeds is the only way to get kills/assists
