Is the applied behaviour analysis an appropriate method to teach individuals with developmental disabilities to protect themselves against COVID-19?

Hope this is helpful.

Thank you for your opinion.

Applied behaviour analysis (ABA) is a scientific approach to understanding behaviour change and not a method or procedure in and of itself. Therefore, any techniques derived from ABA may be beneficial for teaching and promoting any skills that require someone to do something different (e.g., washing hands, wearing masks, staying 6 feet apart etc.) due to COVID-19. I would consider strategies derived from ABA such as behavioural skills training (BST), chaining and backwards chaining and related ideas such as a task analysis.
