A new Illinois law requires any student considered a senior at LPHS to show proof of having had two doses of a meningococcal conjugate vaccine. If the first dose was given after age sixteen only one dose will be required. See the Illinois Department of Public Health website for further information. Please provide this information by the first day of the school year. Students who do not show proof of this vaccine may not be able to attend school at LPHS. A receipt of purchase will not be accepted, the proof will need to have the signature of person who gave the vaccine along with the date of administration.
