Prevenar against Invasive Pneumococcal Disease

Invasive Pneumococcal Disease (IPD) is an acute bacterial disease caused by Streptococcus pneumoniae.

Streptococcus pneumoniae is a leading cause of death and illness in infants, elderly and in patients with certain underlying medical conditions. It causes invasive infections like bacteremia (bacteria in the blood) and meningitis ( inflammation of the protective membranes covering the brain and spinal cord), pneumonia and other lower respiratory tract infections and upper respiratory tract infections including otitis media (ear infection) and sinusitis.

Prevenar ( pneumococcal conjugate vaccine, 7-valent) is thus recommended to prevent IPD for infants as early as 6 weeks old to 9 years of age.

For infants, 4 doses of Prevenar is recommended. Dose 1 is given at 2 months, Dose 2 at 4 months, Dose 3 at 6 months and Dose 4 at 12-15 months of age.

For previously unvaccinated children greater than or equal to 7 months of age the following schedule is followed:
1. If the infant is between 7 to 11 months old, 3 doses are recommended.
2. If the infant is between 12 to 23 months old, 2 doses are recommended.
3. If the child is more than 24 months old, 1 dose is recommended.

The most common adverse effects after vaccination are injection site reactions (swelling, redness, tenderness) and fever.

My nephew already received his 3 shots of Prevenar when he was less than 1 year old. His last dose will be given when he's around 15 months.
