Answer:
In Lincoln Elementary School.
Explanation:
I advise them to send Jackson to Lincoln Elementary School which has 95% vaccination rate for MMR because there is less chances of having measles to Jackson as compared to Oak Crest Elementary School having 80% vaccination rate for MMR. Yes, Jackson is at risk of contracting measles because of no immunity acquire against measles disease by its body. The vaccine can provides immunity to Jackson from the disease but he can't take it due to allergy.
