If 50% of all infections are fully asymptomatic, and most infections are in young people, the median cost of a COVID-19 infection might be as low as $100-$200 USD, which is still many times the cost of a vaccine 
Worth noting that this is also just the DIRECT medical cost (i.e. medications, hospital etc), if you included the INDIRECT costs of infections (time off work, social upheaval etc) infections would be even more expensive
