I've come across a few heartbreaking stories recently about children tragically passing because of meningitis. I have a 2.5 year old who has received all his vaccines but it's making me think back to him moving around a lot during his one year vaccinations and I just had a horrible thought of them not being administered properly. I did ask the nurse if he had properly received them all and she said yes but it's making me wonder and if I should pay privately for boosters when he's of school age. I understand I am coming across paranoid but I read that men b immunity only lasts 3-5 years anyway.
