Please use singular and plural forms correctly. For example, you should say “The most common sign is abnormal vaginal bleeding” (not “The most common signs and symptoms is abnormal vaginal bleeding”).
You should say “too late to be curable” (not “late to be curable”) and “protect against HPV infection” (not “protect HPV infection”).
Please use upper and lower case letters correctly. For example, you should write “In conclusion, vaccination....” (not “In conclusion, Vaccination....”).
