What are the health implications of delaying the third and fourth dose?
Four doses of PCV7 provide the best protection, but children who have received three doses should also have a very high level of protection. Children who have had two doses should also have some protection, but the exact level is unknown. Delaying the third and fourth doses of PCV7 is not ideal. However, this step will help ensure that all children receive at least two doses of the vaccine.
